The image distance is negative, this means the image is formed behind the mirror, at a distance of 13.33 cm behind the sunglasses.

Since the sunglasses have a convex surface, we can use the mirror equation:

1/f = 1/do + 1/di

where f is the focal length of the mirror, do is the object distance (the distance between the object and the mirror), and di is the image distance (the distance between the mirror and the image).

In this case, f = -20.0 cm (since the mirror is convex), do = 40.0 cm (since your face is 40.0 cm from the sunglasses), and we want to find di.

Substituting these values into the mirror equation, we get:

1/(-20.0 cm) = 1/(40.0 cm) + 1/di

Simplifying this equation, we get:

-0.05 = 0.025 + 1/di

Subtracting 0.025 from both sides, we get:

-0.075 = 1/di

Dividing both sides by -0.075, we get:

di = -13.33 cm.

Answer:D. Jupiter is the closest outer planet to the Sun.

\(\tt \: \pink {Option \: D}\)

\(:\implies\)Jupiter is the closest outer planet to the Sun.

A star is considered circumpolar if it remains above the horizon throughout the entire night. The greatest distance that a star can be from Polaris, the North Star, and still be circumpolar is 50°.

Circumpolar stars are those that do not set below the horizon but instead appear to revolve around the celestial pole. In the northern hemisphere, Polaris serves as the North Star, located very close to the celestial north pole.

For a star to be circumpolar as seen from Philadelphia (latitude 40.0°), it must remain above the horizon at all times during the night.

The distance between Polaris and the celestial pole is equivalent to the observer's latitude. In this case, since the latitude of Philadelphia is 40.0°, any star within 40.0° of Polaris will be circumpolar.

Therefore, the greatest distance a star can be from Polaris and still be circumpolar is 40.0° + 10.0° (as the North Star is approximately 10.0° away from the celestial pole), giving a total of 50.0°.

Any star within this range, up to 50.0° from Polaris, will never dip below the horizon and will remain visible throughout the entire night as a circumpolar star.

In order to meet up at the trailing edge, the molecules going over the top of the wing must travel faster than the molecules moving under the wing. Because the upper flow is faster, then, from Bernoulli's equation, the pressure is lower. The difference in pressure across the airfoil produces the lift.

Airplane wings are shaped to make air move faster over the top of the wing. When air moves faster, the pressure of the air decreases. So the pressure on the top of the wing is less than the pressure on the bottom of the wing. The difference in pressure creates a force on the wing that lifts the wing up into the air.

Bernoulli's Principle, states that pressure decreases when air moves faster. Air moves faster over the top of a wing, which results in an area of lower pressure. Meanwhile, the bottom of the wing experiences higher pressure. Camber increases the difference in air pressure between the top and bottom surfaces.

Newton's first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. This tendency to resist changes in a state of motion is inertia.

A force is an effect that can alter an object's motion according to physics. When a mass-containing object increases its velocity, such as when it travels away from rest, a force can cause it to accelerate. A push or a pull is a straightforward method to explain force.  

A force is a vector quantity since it has both magnitude and direction. It is calculated using the newton SI unit (N). Force is denoted by the letter F. (formerly P).

Explanation:

Given that,

Initial position, h₀ = 50 m

A rock is tossed straight up into the air with a velocity of 20.0m/s

(a) When the rock reaches its maximum height, its final velocity, v = 0. Using equation of kinematics as follows :

v=u+at

here, a = -g

\(t=\dfrac{u}{g}\\\\t=\dfrac{20\ m/s}{10\ m/s^2}\\\\t=2\ s\)

(b) Let h is the maximum height reached by the toss. It can be given by :

\(h=h_0+ut-\dfrac{1}{2}gt^2\\\\h=50+20\times 2-\dfrac{1}{2}\times 10\times 2^2\\\\h=70\ m\)

(c) Let T is the time it takes the rock to reach the ground. It is equal to the sum of time reaches to its maximum height and the remaining time. It can be calculated as follows :

\(T=t+\sqrt{\dfrac{2h}{g}}\)

Putting all the values,

\(T=2+\sqrt{\dfrac{2\times 70}{10}}\\\\T=5.74\ s\)

Answer: 35 m/s

Explanation: Gravitational acceleration only affects the vertical component of motion meaning the horizontal component never changes. This means 35 m/s is the correct answer.

A projectile is fired horizontally at an initial horizontal speed of 35 meters per second from a height of 65 meters, after falling 25 meters, the projectile's horizontal speed is 35 m/s.

The distance traveled in relation to the time it took to travel that distance is how speed is defined. Since speed simply has a direction and no magnitude, it is a scalar number.

Speed is calculated using the formula s=d/t, where s is the speed in m.s⁻¹, d is the distance in m, and t is the time in s.

Variable speed is when an object travels a different distance at the same time intervals, whereas uniform speed is when an item travels the same distance at the same time intervals.

1) Determine the mass of the expelled CO2, 2) Calculate the acceleration of the CO2 using Newton's second law, and 3) Multiply the mass by the acceleration to obtain the force exerted by the CO2 on the system.

Newton's second law states that the force exerted on an object is equal to the mass of the object multiplied by its acceleration. To apply this principle to predict the force exerted by expelled CO2 on a system, the following steps can be followed:

Determine the mass of the expelled CO2: This can be achieved by measuring the mass of the CO2 or using known properties such as the molar mass of CO2 and the quantity of CO2 expelled.

Calculate the acceleration of the CO2: The acceleration can be determined by considering the forces acting on the CO2. In this case, the main force acting on the CO2 would be the expulsion force. Other factors such as air resistance can be taken into account if necessary.

Multiply the mass by the acceleration: Once the mass and acceleration are determined, multiply them together to obtain the force exerted by the CO2 on the system. The unit of force is typically Newtons (N).

By following this method and applying Newton's second law, it is possible to predict the force exerted by the expelled CO2 on the system. It is important to ensure accurate measurements and consider all relevant forces to obtain a reliable prediction.

Answer:

To keep everyone safe

Explanation:

Without rules people could get hurt

The handle of a metal spoon submerged in boiling soup feels hot due to the process of heat transfer. Heat energy travels from the hot soup to the metal spoon through a process called conduction. In this process, the hot molecules of the soup transfer their energy to the metal molecules of the spoon, which then vibrate rapidly and increase in temperature.

As the spoon gets hotter, some of the heat energy is conducted through the handle, making it feel hot to the touch. Additionally, metals are good conductors of heat, meaning they can easily transfer heat energy from one area to another. This makes the handle of the metal spoon particularly susceptible to becoming hot when submerged in a hot liquid.

In summary, the handle of a metal spoon submerged in boiling soup feels hot because of the transfer of heat energy from the hot soup to the metal spoon through the process of conduction, and the good heat conductivity of the metal material.

1. i.  The Final Velocity at the end of first interval is  53.33 m/s    

ii.  The Final Velocity at the end of second interval is -6.67 m/s

  iii. The Final Velocity at the end of third  interval is 41.73 m/s 2. The graph is attached

Distance traveled in the first time interval (12 sec) = 320 m

Distance traveled in the second time interval (12 sec) = 300 m

Distance traveled in the third time interval (12 sec) = 180 m

Time interval for each segment = 12 sec

First time interval (12 sec, distance = 320 m):

Distance = (Initial Velocity × Time) + (0.5 × Acceleration × Time²)

320 = (0 × 12) + (0.5 × Acceleration × 12²)

320 = 0.5 × Acceleration × 144

Acceleration = (320 × 2) / (144)

Acceleration = 4.444 m/s²

Using the equation: Final Velocity = Initial Velocity + (Acceleration × Time)

Final Velocity = 0 + (4.444 × 12)

Final Velocity = 53.33 m/s

Second time interval (12 sec, distance = 300 m):

Distance = (Initial Velocity × Time) + (0.5 × Acceleration × Time²)

300 = (53.33 × 12) + (0.5 × Acceleration × 12²)

300 = 639.96 + (0.5 × Acceleration × 144)

Acceleration = (300 - 639.96) / 72

Acceleration = -5 m/s²

Final Velocity = Initial Velocity + (Acceleration × Time)
Final Velocity = 53.33 + (-5 × 12)

Final Velocity = -6.67 m/s

Third time interval (12 sec, distance = 180 m):

Distance = (Initial Velocity × Time) + (0.5 × Acceleration × Time²)

180 = (-6.67 × 12) + (0.5 × Acceleration × 12²)

180 = -80.04 + (0.5 × Acceleration × 144)

Acceleration = (180 - (-80.04)) / 72

Acceleration = 4.45 m/s²

The acceleration due to gravity on the planet Htrae is 20 m/s², thus  the correct answer is D. 20 m/s.

The acceleration due to gravity is the acceleration an object experiences due to the gravitational force acting on it. The acceleration due to gravity is denoted by the symbol 'g'. It is a vector quantity that is always directed towards the center of the planet or celestial body.

The formula for calculating the acceleration due to gravity is given as: g = (GM)/R² where G is the gravitational constant, M is the mass of the planet or celestial body, and R is the distance between the center of the planet or celestial body and the object. The acceleration due to gravity is expressed in meters per second squared (m/s²).

Given that the weight of the object on Earth is 450 N, and on planet Htrae, it is 900 N. We know that the weight of an object is the product of its mass and the acceleration due to gravity. Therefore, we can write: Weight = Mass * acceleration due to gravity.

On Earth, the weight of the object is 450 N. Thus, Mass * acceleration due to gravity on Earth = 450 N. On planet Htrae, the weight of the object is 900 N. Thus, Mass * acceleration due to gravity on Htrae = 900 N.

Dividing the second equation by the first equation, we get: (Mass * acceleration due to gravity on Htrae) / (Mass * acceleration due to gravity on Earth) = 900 N/450 N. Cancelling out the masses, we get: Acceleration due to gravity on Htrae / Acceleration due to gravity on Earth = 2.

Solving for the acceleration due to gravity on Htrae, we get: Acceleration due to gravity on Htrae = 2 * Acceleration due to gravity on Earth. Given that acceleration due to gravity on Earth is 9.8 m/s², the acceleration due to gravity on Htrae is: Acceleration due to gravity on Htrae = 2 * 9.8 m/s²= 19.6 m/s² ≈ 20 m/s².

Thus, the acceleration due to gravity on the planet Htrae is 20 m/s².

When a process is said to be at a certain sigma level, it refers to its level of process performance or capability.

Sigma (σ) is a statistical term that represents the standard deviation of a process, which measures the variability or spread of data within that process. In the context of process improvement methodologies like Six Sigma, sigma level is used as an indicator of process quality and defect rate.

A process at 4 sigma level means that it exhibits a level of performance where the process variation is such that there are about 6.68 defects per million opportunities (DPMO), or a defect rate of 0.000668%. This level of performance indicates that the process has a relatively higher variability and there is room for improvement to reduce defects and improve quality.

On the other hand, a process at six sigma level represents a higher level of process performance. It means that the process exhibits a very low level of variation, with only about 3.4 defects per million opportunities (DPMO), or a defect rate of 0.000034%. A six sigma level process is considered to be highly capable and aims to achieve near-perfection in terms of quality and minimizing defects.

Comparing a process at 4 sigma level to a process at six sigma level, the key difference lies in the level of process performance and the associated defect rates. A process at six sigma level has significantly lower variation and defect rate compared to a process at 4 sigma level. The six sigma level represents a higher standard of quality and is more reliable and consistent in delivering products or services with minimal defects. The 4 sigma level, while still considered good, has a higher potential for improvement and may benefit from further efforts to reduce variation and defects to achieve higher levels of quality and process capability.

In astronomy, the eccentricity aspect of the astronomical theory refers to the shape of an object's orbit around another object. Specifically, it measures how much an orbit deviates from a perfect circle.

The eccentricity of an orbit is defined as the ratio of the distance between the two foci of the ellipse that describes the orbit to the length of the major axis of the ellipse. An orbit with an eccentricity of 0 is a perfect circle, while an orbit with an eccentricity of 1 is a parabola, and an orbit with an eccentricity greater than 1 is a hyperbola. In the context of the Solar System, the eccentricity of a planet's orbit determines how close it comes to the Sun at its closest approach (perihelion) and how far away it gets at its furthest point (aphelion).

For example, the eccentricity of Earth's orbit is about 0.0167, which means that its distance from the Sun varies by about 3.1 million miles (5 million kilometers) between perihelion and aphelion. The eccentricity of an orbit can have important effects on the object that is orbiting. For example, objects with highly eccentric orbits may experience significant changes in temperature or gravitational forces as they move closer to or further away from the object they are orbiting.

This can have important consequences for the object's physical and chemical processes, and may even contribute to the development of life in some cases.
