What are the two goals of the Artemis Mission?

Answer:

60

Explanation:

(hint: speed = distance/time)

The average speed for this trip will be \(\rm 60 mile\ hr^{-1}\). The ratio of the total distance and time is average velocity.

The total distance traveled by an object divided by the total time taken is the average speed.

The average speed of an object indicates the pace at which it will traverse a distance. The metric unit of speed is the meter per second.

The given data in the problem is;

t is the time taken = 5 hour

d is the distance tyravelled=300 miles

The average velocity is found as;

\(\rm v_{avg} = \frac{d_{total}}{t{total}} \\\\\ \rm v_{avg} = \frac{300}{5} \\\\ \rm v_{avg} = 60 mile\ hr^{-1}\)

Hence the average speed for this trip will be \(\rm 60 mile\ hr^{-1}\)

The forces acting on free rolling body are friction force and force of gravity.

Gravity is the force exerted by a planet or other body on objects to attract them toward its center. The force of gravity is responsible for keeping planets in orbits.

The earth also exert force of gravity on all object which are freely falling. A rolling object is rolling downward along the slope because of force of gravity.

Force of friction acts on an object when it moves on the surface of another object. This force always opposes motion. This acts as reaction force of motion.

Explanation:

The definition of velocity and the graphical analysis allows to find the correct answer for the velocity of a body moving in the negative direction is:  

     c) A downward-sloping line segment

Kinematics studies the movement of bodies, establishes relationships between position, velocity and acceleration.

Velocity is defined as the change of position in the time interval.

      \(v= \frac{\Delta x}{\Delta t}\)  

In a graph of this expression, time is placed on the x-axis and the position on the y-axis.

In general, if the final position is greater than the initial position, the speed is positive and the slope must be upward sloping.

If the final position is less than the initial position, the velocity is negative and the slope of the graph is downward sloping, in the attachment we can be this type of graph.

Let's review the different answers:

a) False. This velocity is positive.

b) False. In this case the speed is vertical.

c) True. The final position is less than the initial position, therefore the velocity is negative.

d) False. In that case there is no change in position, therefore the velocity is zero

In conclusion, using the definition of velocity and graphical analysis we can find the correct answer for the velocity of a body moving in the negative direction is:

Answer:

energy transfer electric to heat

Answer:

At the point of dropping the object, by Newton's first law due to gravitational force \(F_g\) = m × g, accelerates

By Newton's Second law the object reaches impacts on the air with the gravitational force resulting in changing momentum of m×(Final Velocity - Initial Velocity)

As the velocity increases, the rate of change of momentum becomes equivalent to the gravitational force and by Newton's third law, the action action and reaction are equal and opposite hence they cancel each other out

The body then moves at a constant uniform motion down according to Newton's first law

Explanation:

At the point the object of mass, m, is dropped from the height of the tower, the only force acting on the object is the gravitational force such that the object has an acceleration which is the acceleration due to gravity, g, and the gravitational force is therefore = m × g

As the speed of the object increases while the object is falling with the gravitational acceleration the rate at which the object cuts through layers of air which (by Newton's first law of motion, are at rest ) has some buoyancy effect also increases therefore, the object is constantly increasingly changing the momentum of the air which by Newton's second law results, at an high enough velocity, and by Newton's third law, in a force equal to the applied gravitational force

Therefore, the force of the air drag becomes equal to the gravitational force, cancelling each other out and the object then moves according to Newton;s first law, in uniform motion of a constant speed while still falling down.

Energy  is a quantitative property given to a body or physical system, identifiable in the performance of work or in the form of heat and light. Standard mechanical size. Energy is Conserved - The law of conservation of energy states that energy can be transformed into form, but cannot be created or destroyed. The unit of measure for energy in the International System of Units (SI) is the joule (J). Common forms of energy include the kinetic energy of moving bodies, the potential energy stored in bodies (due to their position in the field, etc.), the elastic energy stored in fixed bodies, the chemical energy associated with chemical reactions, Radiant energy carried by electromagnetic radiation and internal energy contained in thermodynamic systems. All living things absorb and emit energy all the time.

Energy = Power x Time

  Time = 25 minutes

            = 25 x 60 sec = 1500 sec

Power = 75 watt

Energy = 75 x 1500

The centripetal force that must be exerted against the wings to keep the plane moving in a circle is 3.71 × 10⁴ N.

Given that,

Time = 30 min = 30 × 60 sec = 1.8 × 10³ s

Radius = 50 km = 50× 10³ m = 5× 10⁴ m

We know the expression for velocity as,

v = 2πr/(T) = (2π×5× 10⁴) /(1.8 × 10³) = (π×10⁵)/(1.8 × 10³) = (100× 3.14)/1.8 = 174.44 m/s ≈ 175 m/s

Mathematically, centripetal force can be written as,

F = mv²/r = (60,500× 175²)/(5× 10⁴) = 3.71 × 10⁴ N

Thus, required centripetal force is 3.71 × 10⁴ N.

When a wheel which initially at rest, has a moment of inertia of 2.0 kg-m2 and then a torque is applied on the wheel, then the wheel would have have turned by 750 rad.

In physics, moment of inertia is a quantitative measure of the rotational inertia of a body, that is the opposition that the body exhibits to having its speed of rotation about an axis changed by the application of torque.

Given torque, τ = 30 N-m

Moment of inertia, I = 2kg-m²

time = 10sec

As we know that , τ = l α

So,  α = τ/I

= 30/2

α = 15 rad/s²

As wheel starts from rest, so initial angular velocity,ω₀ = 0

Now, displacement,Ф = ω₀t + 1/2 α t²  

= 0 * 10 + 1/2 * 15 *10²

Answer:

(a) 477 m

(b) 44.6 s

(c) 21.16 m

(d) 19.24 m

Explanation:

initial speed, u = 77km/h = 21.4 m/s

acceleration, a = - 0.48 m/s2

final speed v =  0  

(a) let the stopping distance is s.

Use third equation of motion

\(v^2 = u^2 + 2 a s\\\\0 = 21.4^2 - 2 \times 0.48\times s\\\\s = 477 m\)

(b) Let t is time.

Use first equation of motion

v = u + at

0 = 21.4 - 0.48 t

t = 44.6 s

(c) Let the distance is s in first second.

Use second equation of motion

\(s = u t + 0.5 at^2\\\\s = 21.4\times 1 - 0.5\times 0.48\times 1\\\\s = 21.4 - 0.24 = 21.16 m\)

(d) distance traveled in 5 th second is given by

\(s = u + 0.5 a (2 n - 1) \\\\s = 21.4 - 0.5\times 0.48 \times (2\times 5 -1)\\\\s= 21.4 - 2.16 = 19.24 m\)

To prove that rock layers in one area match rock layers found in another area, geologists use the principles of stratigraphy, including fossil, lithologic, and chemical correlation techniques.

One way to prove that rock layers in one area match rock layers found in another area is by using the principle of stratigraphy, which is the study of rock layers (strata) and their relationships. Geologists can use several techniques to correlate rock layers between different locations, including:

Fossil correlation: If a particular fossil is found in two different rock layers at different locations, it is a good indicator that the layers are of the same age. This is because certain fossils only existed during specific time periods, and so if the same fossil is found in two different rock layers, it can be inferred that those layers were deposited during the same time period.

Lithologic correlation: Rocks can have unique characteristics that allow geologists to match them to other rocks of the same type. For example, sandstone can have unique grain sizes or shapes that can help identify it as coming from a specific location.

Chemical correlation: Some rocks have unique chemical compositions that can be used to match them to other rocks of the same type. For example, volcanic rocks can have unique isotopic signatures that can help identify them as coming from a specific volcano.
