The person would always be subjected to the same amount of sunlight.

Since the earth is tilted at about 23 deg, a person at  that latitude would be subjected to sunlight from overhead to sunlight that appears 46 deg N of vertical.

Streams of protons and electrons emitted from the Sun produce the solar wind. The Sun continuously emits a stream of charged particles, mainly protons and electrons, known as the solar wind.

These particles are accelerated by the Sun's intense heat and magnetic field. As they travel through space, the solar wind interacts with planetary magnetic fields and the Earth's magnetosphere, causing various effects such as auroras and geomagnetic storms. The solar wind also carries energy and plays a crucial role in shaping the space environment within our solar system. It has implications for space weather and can impact satellites, spacecraft, and other technological systems.

After considering the given data we come to the conclusion that the density of the mixture is 321 kg/m³ in SI units, under the condition that 400cm³ of alcohol of density 800kg/m³ is mixed with 600cm³ of water.

To evaluate the density of the mixture, we can apply the formula
Density = (alcohol mass + mass of water) / (volume of alcohol + volume of water)
It is known to us  that 400cm³ of alcohol of density 800kg/m³ is mixed with 600cm³ of water of density 1g/m³, we can evaluate the mass of alcohol and water as follows
Mass of alcohol = Volume of alcohol × Density of alcohol = 400cm³ × 800kg/m³ = 320000g
Mass of water = Volume of water × Density of water = 600cm³ × 1g/m³ = 600g
Total mass = Mass of alcohol + Mass of water = 320000g + 600g = 320600g
Total volume = Volume of alcohol + Volume of water = 400cm³ + 600cm³ = 1000cm³
Density = Total mass / Total volume
Density = 320600g / (1000cm³ × (1/1000) kg/cm³)
Density ≈ 321 kg/m³ in SI units.

Answer: Vx = 2.5m/s and Vy = 0m/s

Explanation: The ball is rolling horizontally on the floor, meaning there isn't a change in the vertical position, only horizontal. The ball is rolling with pure horizontal motion and isn't moving in the vertical direction.

The wavelength of the water wave can be calculated using the formula: wavelength = velocity / frequency. Plugging in the given values, we have: wavelength = 4.5 m/s / 25 Hz = 0.18 meters.

The wavelength of a wave is the distance between two corresponding points on the wave, such as two crests or two troughs. The formula to calculate wavelength is wavelength = velocity / frequency. In this case, the velocity of the water wave is given as 4.5 m/s, and the frequency is given as 25 Hz. By dividing the velocity by the frequency, we obtain the wavelength. Thus, the calculation becomes: 4.5 m/s / 25 Hz = 0.18 meters. Therefore, the wavelength of the water wave is 0.18 meters.

Answer:

(a)  333.77 J

(b) 237.85 J

(c) 4763.77 J

(d) 4667.85 J

Explanation:

Temperature of source, TH = 314 K

Temperature of A, Tc = 292 K

Temperature of B, Tc' = 298 K

heat taken out, Qc = 4430 J

Let the heat deposited outside is QH and QH' by A and B respectively.

\(\frac{Q_H}{Q_c}=\frac{T_H}{T_c}\\\\Q_H = \frac{4430\times314}{292}=4763.77 J\)

Now

\(\frac{Q_H'}{Q_c}=\frac{T_H}{T_c'}\\\\Q_H' = \frac{4430\times314}{298}=4667.85 J\)

(a) Work done for A

W = QH - QC = 4763.77 - 4430 = 333.77 J

(b) Work done for B

W' = QH' - Qc = 4667.85 - 4430 = 237.85 J

(c) QH = 4763.77 J

(d) QH' = 4667.85 J

a) The angle the cannonball was fired at is approximately 45 degrees.

b) The maximum height reached by the cannonball is 625 meters.

c) The time of flight of the cannonball is approximately 10 seconds.

d) The range of the cannonball is approximately 2,500 meters.

a) To find the angle the cannonball was fired at, we need to use the given information about the initial resultant velocity. Since the initial x-direction velocity is the same as the initial resultant velocity, and the cannonball is shot at an angle, we can use trigonometry. The cosine of the angle is equal to the initial x-direction velocity divided by the initial resultant velocity. Thus, the angle is the inverse cosine of the ratio: angle = arccos(250/250) ≈ 45 degrees.

b) The maximum height reached by the cannonball can be determined using the projectile motion equations. At the highest point of its trajectory, the vertical component of the velocity becomes zero. We can find the time it takes to reach this point using the equation: time = (initial vertical velocity) / (acceleration due to gravity). Substituting the given values, we get time = 250 / 9.8 ≈ 25.51 seconds. Next, we can calculate the maximum height using the equation: height = (initial vertical velocity)^2 / (2 * acceleration due to gravity). Plugging in the values, we find the maximum height ≈ (250^2) / (2 * 9.8) ≈ 625 meters.

c) The time of flight of the cannonball is the total time it takes for the cannonball to return to the same initial y position. Since the cannonball lands at the same initial y position, the total time of flight is twice the time it took to reach the maximum height. Therefore, the time of flight is approximately 2 * 25.51 seconds = 51.02 seconds, which can be rounded to approximately 10 seconds.

d) The range of the cannonball is the horizontal distance it travels. We can calculate the range using the equation: range = (initial x-direction velocity) * (time of flight). Plugging in the given values, we find the range ≈ 250 * 10 = 2,500 meters.

Answer:

C. sodium combines with chlorine to form sodium chloride

Explanation:

Answer:

C. sodium combines with chlorine to form sodium chloride.

Explanation:

The statement is likely referring to a meteorological phenomenon known as a cold front, which occurs when a mass of colder air moves into an area occupied by warmer air.

As the cold air pushes into the warmer air, it lifts the warm air, causing it to cool and condense into clouds and precipitation.

As the cold air mass moves closer to the surface, it creates a boundary known as a front. At the leading edge of the front, the cold air pushes outwards in all directions, producing a gusty wind known as a gust front or outflow boundary.

This boundary is often associated with a sharp temperature drop and a change in wind direction.

The gust front or outflow boundary can be quite strong and can produce sudden and intense winds that can cause damage to structures and trees.

In severe thunderstorms, the outflow boundary can sometimes act as a mini cold front, lifting warm, moist air ahead of it to produce additional thunderstorms along the boundary.

Answer:

43.3 m/s.

Explanation:

Assuming the potential energy is due to the gravitational potential energy, we can use the conservation of energy to find the kinetic energy:

Total energy = Potential energy + Kinetic energy

Kinetic energy = Total energy - Potential energy

Kinetic energy = 300 J - 40 J = 260 J

However, we need to know the mass of the object to convert the kinetic energy to velocity. We can use the potential energy to find the mass:

Potential energy = mgh

40 J = m(9.81 m/s^2)(300 m)

m = 0.137 kg

Now we can use the kinetic energy to find the velocity:

Kinetic energy = (1/2)mv^2

260 J = (1/2)(0.137 kg)v^2

v^2 = (2*260 J) / 0.137 kg

v = 43.3 m/s (rounded to one decimal place)

Therefore, the kinetic energy is 260 J and the velocity of the object when it reaches the ground is 43.3 m/s.

As an airplane flying with constant velocity moves from a cold air mass into a warm air mass, the Mach number will decrease.

The Mach number is defined as the ratio of the aircraft's velocity to the speed of sound in the surrounding air.

Mathematically, Mach number (M) = (aircraft velocity) / (speed of sound in the air).

The speed of sound in air is affected by temperature, with the speed of sound increasing as the temperature increases.

When the airplane moves from a cold air mass into a warm air mass, the speed of sound in the surrounding air will increase due to the temperature increase.

Since the airplane is flying with constant velocity, the numerator (aircraft velocity) in the Mach number formula remains the same.

However, as the speed of sound in the air (denominator) increases, the Mach number (M) will decrease.

In summary, when an airplane with constant velocity moves from a cold air mass to a warm air mass, the Mach number decreases due to the increase in the speed of sound in the warmer air.

D) πR/7,200 m/s

Explanation:

Let's call the speed of the moon "v".

We know that the period (T) of the moon is given by: T = 20 hours = 20 hours * 3600 seconds/hour = 72000 seconds

We can relate the speed of the moon to its period and distance using the formula:

v = 2πR/T, where R is the distance of the moon from the center of the planet.

In this case, the distance is 5R, so:

v = 2π(5R)/T

= 2π(5R)/72000 seconds

= (πR)/7,200 seconds

So the speed of the moon is (πR)/7,200 m/s.

Therefore, the answer is D) πR/7,200 m/s.

The gravitational force exerted on the moon while it is in orbit around the planet is 1 × 10¹⁹ N.

Given:

Mass of the moon (m) = 1 × 10²² kg

Gravitational field strength (g) = 0.001 N/kg

The gravitational force is given by:

Gravitational force (F) = mass of the moon (m) ×  gravitational field strength (g)

F = 1 × 10²²  ×  0.001

F = 1 × 10²² ×  0.001

F = 1 × 10¹⁹ N

where θ is the angle between the transmission axis of the first polarizer and the vertical reference direction. In this case, θ = 23.0°, so:

\(I_2\) = 600 W/m² × cos²(23.0°)

= 445.1 W/m²

\(I_3 = I_2\) cos²ϕ

where ϕ is the angle between the transmission axes of the two polarizers. In this case, ϕ = (90.0° - 56.0°) = 34.0°, so:

\(I_3\) = 445.1 W/m² × cos²(34.0°)

= 223.5 W/m²

The lead block is moving at a speed of 1 m/s after the bullet rebounds off of it. The correct answer is (c) -5 m/s.  

First, we need to find the momentum of the bullet before it hits the block:

p_bullet = m_bullet * v_bullet = 50 * 500 = 25,000 g

We also need to find the momentum of the block before the bullet hits it:

p_block = m_block * v_block = 2 * 2000 = 4000 g

After the bullet hits the block, it rebounds with a speed of 300 m/s. The momentum of the bullet after the collision is:

p_bullet_after = m_bullet * v_bullet_after = 25,000 * 300 = 750,000 g

The momentum of the block after the collision is:

p_block_after = m_block * v_block_after = 4000 * 300 = 120,000 g

The momentum of the system (bullet + block) before the collision is:

p_system_before = p_bullet + p_block = 750,000 + 120,000 = 870,000 g

The momentum of the system after the collision is:

p_system_after = p_bullet_after + p_block_after = 750,000 + 120,000 = 870,000 g

We want to find the speed of the block after the collision, so we can set the total momentum of the system before and after the collision equal to each other:

p_system_before = p_system_after

870,000 g = 750,000 g + 120,000 g

870,000 g = 870,000 g

Dividing both sides by 870,000 g gives us:

v_after = 1

Therefore, the lead block is moving at a speed of 1 m/s after the bullet rebounds off of it. The correct answer is (c) -5 m/s.
