Mechanical energy – It is the sum of microscopic kinetic and potential
energies.
92.
Momentum is conserved in elastic collision but not in inelastic collision
93.
On earth, a moving body ordinarily comes to rest by itself because of the ---
Forces of friction
94.
If the momentum of a certain body is increased by 50% then increases in the
Kinetic energy of the body will be------- 125%
95.
If a force F is applied on a body and it moves with Velocity V, the power will
be ------- F*V.
96.
One kilowatt hour is equal to ---------- 36, 00,000 joules (3.6 mega-joules)
97.
The hydraulic brakes used in automobiles is a direct application of ------
Pascal’s Law
98.
A liquid rises in a capillary tube when the angle of contact is ---------- an
acute angle
99.
The rise of liquid in a capillary tube has a meniscus. If the angle of contact
is 900 the shape of the meniscus is------------Concave
100.
The kinetic theory of gases ------- explains the behavior of an ideal gas
