List three methods of energy transport in nature and explain how the energy is being transferred in each of those methods. Which two are means by which energy is transported inside the Sun?

This question is for my college astronomy class!

Answer:

V = S / d = 60 m / 1.5 sec = 40 m/s

Note 40 m/s = 40 * 3.28 = 131 ft/sec

131 ft/sec =  131 ft/sec / (88 ft/sec / 60 mph) =   89 mi/hr

Option "C" is your answer!

The kinetic energy of the object depends on its mass and velocity

The graph of the straight line shown in option C is the correct representation of the relationship between mass and KE of the object.

What is kinetic energy?

The kinetic energy of an object is the energy that an object or a particle has by reason of its motion. Kinetic energy is a property of a moving object or particle and depends not only on its motion but also on its mass.

The kinetic energy of an object is given by the expression.

[tex]KE = \frac{1}{2} {mv}^{2} [/tex]

Where KE is the kinetic energy, m is the mass and v is the velocity of the object.

The above expression of the kinetic energy shows that it is directly proportional to the mass of the object.

KE x m

If we show this relation of mass and KE on a graph, then it would be a straight line showing the direct proportionality between mass and KE of the object.

Hence we can conclude that the graph of the straight line shown in option C is the correct representation of the relationship between mass and KE of the object.

The net force acting on the wagon when it is pulled at a constant speed is zero (0).

The net force acting on an object is the sum of all the forces acting on the object. The net force on an object is determined by applying Newton's second law of motion as shown below;

F(net) = ma

where;

Constant speed is a situation where the speed of the object does not change with time.

At constant speed, the acceleration of the object is zero (0).

F(net) = m x 0

F(net) = 0

Thus, the net force acting on the wagon when it is pulled at a constant speed is zero (0).

Explanation:

Since the acceleration is constant, we use the big four equations.

[tex]x = x _{i} + vt[/tex]

[tex]x = \frac{1}{2} a {t}^{2} + v _{i}t + x _{i}[/tex]

[tex]v {}^{2} = (v _{i}) {}^{2} + 2a(x - x _{i})[/tex]

[tex] \frac{1}{2} (v + v _{i})t = x - x _{i}[/tex]

Next. identity the variables.

We know

t=9.2

change in position or (x- x_i) is 428.8

Initial Velocity is 0.

We need to solve for the final velocity, so we use the fourth equation.

[tex] \frac{1}{2} (v - v _{i})t = x - x _{i}[/tex]

Subsitue

[tex] \frac{1}{2} (v - 0)(9.2) = 428.8[/tex]

[tex] \frac{1}{2} (v)9.2 = 428.8[/tex]

[tex]v = 93.22 \frac{m}{s} [/tex]

Answer:

Explanation:

When the balls meets, the time should be the same, let say t.

For the first ball (released from a loom):

[tex]\bar{h}=\frac{1}{2}gt^{2}[/tex] (Free fall motion) ([tex]\bar{h}[/tex] = the distance travelled by the first ball, measured from the loom)

So, we can find that [tex]\bar{h}=\frac{1}{2}(10t^{2})=5t^{2}[/tex]

For the second ball (which is thrown directly upwards):

[tex]y=v_{o}t-\frac{1}{2}gt^{2} = 25t-5t^{2}[/tex]

Because the height of the loom is h :

[tex]h=\bar{h}+y[/tex]

[tex]h=25t[/tex]

So, the time when two balls meets is : [tex]t=\frac{h}{5}[/tex] (In this question, the height of the loom h is not declared). When the height of the loom is known, you can calculate the time and the value of [tex]\bar{h}[/tex] or y

For an airplane whose speed is 60 m/s is flying at an altitude of 500 m over the ocean toward a stationary sinking ship, the horizontal distance  is mathematically given as

x=606m

Generally, the equation for the y axis distance  is mathematically given as

y=vt+0.5gt^2

Therefore

The period (T) of the right pendulum for small displacements in s is equal to 1.49 seconds.

Mathematically, the time taken by this pendulum to undergo a small displacement is given by this formula:

[tex]T=2\pi \sqrt{\frac{L}{g} }[/tex]

Where:

Scientific data:

Acceleration due to gravity (g) = 9.8 m/s².

Assuming a randomized variable for the length of the rope to be 1.2 meter. Also, we know that the right pendulum has a radius of 1/2L.

1/2L = L/2

L/2 = 1.1/2

L/2 = 0.55 meter.

Substituting the parameters into the formula, we have;

[tex]T=2\times 3.142 \sqrt{\frac{0.55}{9.8} }\\\\T=6.284 \times \sqrt{0.0561} \\\\T=6.284 \times 0.2369[/tex]

Given:

v = 50m/s

u = 0 m/s

a = 5.44 m/s

t = ?

Substitute values into the equation v = u + at

v = u + at

50 = 0 + 5.44 x t

t = 50/5.44

t = 9.19 seconds

Time is in seconds as the velocity and acceleration are in metres per second instead of kilometres per hour

meteor impact this ecological processes is most likely responsible for the formation of the crater. Hence option D is correct.

A collision between celestial objects that has quantifiable effects is called an impact event. The most frequent impact events involve asteroids, comets, or meteoroids and have little impact. However, impact events have been shown to occur often in planetary systems and have physical repercussions. However, many surface impacts are reduced by atmospheres through atmospheric entry when massive objects strike terrestrial planets like the Earth. Nonetheless, there may be major physical and biospheric effects. The majority of the solid objects in the Solar System are covered with impact craters and structures, which provide the best empirical evidence for their frequency and size. Since the birth of the Solar System, impact events appear to have had a substantial impact on how the Solar System has changed. Significant impact events have impacted Earth's history and have been linked

Answer:

Explanation:

Because we assume the pendulum is a "mathematical pendulum" (neglecting the moment of inertia of the bob), we can find:

[tex]T=2\pi\sqrt{\frac{L}{g}} \rightarrow 4=2\pi\sqrt{\frac{L}{9.81}} \rightarrow \frac{4}{\pi^{2}}=\frac{L}{9.81} \rightarrow L \approx 3.97 m[/tex]

By using the [tex]y=A\sin(\omega t) \rightarrow v = \frac{dy}{dt}=\omega A \cos\omega t = \omega\sqrt{A^{2}-y^{2}}[/tex]

The mean position is the position when y = 0, so:

[tex]\omega = \frac{2\pi}{T}=\frac{2\pi}{4}=0.5\pi[/tex] rad/s

and [tex]v = \omega A \rightarrow A=\frac{40}{0.5\pi}=\frac{80}{\pi}[/tex] in centimeters (cm).
