To solve the problem we must know about potential energy and kinetic energy.

What is Kinetic Energy?

It is the type of energy an object has due to its motion. it is directly proportional to the product of mass and the square of the velocity of the object. It is given by the formula,

$K.E. = \dfrac{1}{2}mv^2$

What is Potential Energy?

Potential energy is defined as the energy stored on the object which is relative to its position.

For example, the potential energy of a steel ball at a particular height is more than the steel ball at the ground.

Its potential energy decreases, and kinetic energy increases.

Given

A box slides down a ramp.Explanation

As the box is sliding down the box's kinetic increase will increase due to the increase in its motion while the potential energy of the box will decrease.

Hence, Its potential energy decreases, and kinetic energy increases.

As the box slides down the ramp, its potential energy decreases
and, if there's not too much friction, its kinetic energy increases.

Stars are born within the clouds of dust and scattered throughout most galaxies. a familiar example of such as a dust cloud is the orion nebula. turbulence deep within these clouds gives rise to knots with sufficient mass that the gas and dust can begin to collapse under its own gravitational attraction. as the cloud collapses, the material at the center begins to heat up. known as a protostar, it is this hot core at the heart of the collapsing cloud that will one day become a star. three-dimensional computer models of star formation predict that the spinning clouds of collapsing gas and dust may break up into two or three blobs; this would explain why the majority the stars in the milky way are paired or in groups of multiple stars.therefor, i would say the answer is: dust and gases contract.i hope this ! < 3

In a system with only a single force acting upon a body, what is the relationship between the change in kinetic energy and the work done by the force? answers: work is equal to the change in kinetic energy. work depends on the square of the change in potential energy. work is equal to the negative of the change in kinetic energy. work is equal to the square of the change in kinetic energy

Now that we have a feel for the state of the circuit in its steady state, let us obtain the expression for the current in the circuit as a function of time. note that we can use the loop rule (going around counterclockwise): e−vr−vl=0. note as well that vr=ir and vl=ldidt. using these equations, we can get, after some rearranging of the variables and making the subsitution x=er−i, dxx=−rldt. integrating both sides of this equation yields x=x0e−rt/l. use this last expression to obtain an expression for i(t). remember that x=er−i and that i0=i(0)=0. express your answer in terms of e, r, and l. you may or may not need all these variables. use the notation exp(x) for ex.
