A box slides down a frictionless incline, gaining speed. The work done by the normal force n is _______.
jeka57 [31]

The work done by the normal force n when the box slides down a frictionless incline and gaining speed is zero.

<h3>What is normal force?</h3>

The force of contact is called the normal force. When the two surfaces are in contact with each other, then the normal force acts.

This force is applied by the solid bodies on each other in order to prevent the passing through each other.

A box slides down a frictionless incline, gaining speed. For this box, the value of work done by normal force has to be found out. Let's analyze the given condition.

  • The body is gaining the speed, which means there is a change in kinetic energy.
  • The change in kinetic energy is equal to the work done.
  • The friction force is the product of coefficient of the friction and normal force.
  • The friction force for the given case is zero. Thus, the normal force must be equal to the zero.

Thus, the work done by the normal force n when the box slides down a frictionless incline and gaining speed is zero.

If a system absorbs 155.0 kJ of heat from its surroundings and the system does 45.0 kJ of work on its surroundings, what is the
Ede4ka [16]

The change in the internal energy of the system is 110 kJ.

<h3>What is internal energy?</h3>

Internal energy is defined as the energy associated with the random, disorder motions of molecules.

calculate the change in internal energy, we apply the formula below.

Formula:

  • ΔU = Q-W.................... Equation 1

Where:

  • ΔU = Change in internal energy
  • Q = Heat absorbed from the surroundings
  • W = work done by the system

From the question,

Given:

  • Q = 115 kJ
  • W = 45. 0 kJ

Substitute these values into equation 1

  • ΔU = 155-45
  • ΔU = 110 kJ

Hence, The change in the internal energy of the system is 110 kJ.

A train is travelong at 22 m/s when the condutor gets a radio call about a car stalled on the tracks. He hits the emergancy brak
mylen [45]

Answer:

final velocity = 0

because the train stoped

so,

  • acceleration = (v - u) ÷ t
  • acceleration = (0 - 22) ÷ 135
  • acceleration = -22 ÷ 135

  • acceleration = -0.162 m/s²
