Answer: acceleration can be calculated when a known force is acting on an object of known mass. Newton’s law can be represented by the equation F net = m x a, where F net is the total force acting on the object, m is the object’s mass, and a is the acceleration of the object.
Explanation:
Answer:
The position x, is ± 0.4 m.
Explanation:
The total mechanical energy of the oscillatory motion is given as;
When the kinetic energy (E) is half of the elastic potential energy (U);
Equate (1) and (2)
Thus, the position x, is ± 0.4 m.
Answer:
bumper cars colliding- inelastic
man jumping in a cab- perfectly inelastic
mud sticking to car - perfectly inelastic
hat being sat on door being slammed- inelastic
ball bouncing- elastic
Explanation:
In a perfectly inelastic collision, the objects stick together after collision and move with a common velocity. Maximum kinetic energy is lost during such collision.
For an inelastic collision, kinetic energy is partly lost and the colliding objects move apart at different velocities. This is often encountered in real life situations.
For an elastic collision, both momentum and kinetic energy are conserved. The object rebounds with the same relative velocity with which it approached.
Answer:
An electromagnet is a magnet that runs on electricity. Unlike a permanent magnet, the strength of an electromagnet can easily be changed by changing the amount of electric current that flows through it. The poles of an electromagnet can even be reversed by reversing the flow of electricity.
Answer:
5953.42 J
Explanation:
Given:
Initial volume, 
= 100 in³
Final Volume, 
= 10 in³
Initial pressure = 50 psia
Temperature = 100° F = 310.93 K
For isothermal reversible process, work done is given as:
Work done = 
Where,
R is the ideal gas constant = 8.314 J/mol.K
or
Work done = 
or
Work done = 5953.42 J
