Stells [14]3 years ago

Explanation:

The problem deals with a phase transition from solid to liquid. To the left we have ice and to the right we have liquid water.

For such change to take place, the process of melting must occur. During melting, a solid changes state from solid to liquid by taking energy from the environment.

  • In solid state, the molecules of the water are in a fixed state about their fixed lattice.
  • As the solid ice gains energy from the environment, it begins to melt.
  • Energy increase causes the molecules of the water to start flowing to form a liquid.

The maximum kinetic energy of a box sliding from the top of a ramp to the bottom is A) at the top. B) at the bottom. C) at the e
Readme [11.4K]

Kinetic energy of an object can be expressed in terms of its mass m and velocity v as:

KE = 1/2 * m* v²

Thus higher the velocity, greater will be the Kinetic energy. Now, as the box moves along a ramp from top to bottom, its velocity increases and so does the KE. Hence, kinetic energy is maximum at the bottom

Ans B) at the bottom
