What statement is true? A. interia causees bodies to slow in their motion, unless they're pushed by a force.
B. Interia resist changes to the state of motion of a body.
C. Interia decelerates a body.
D. Interia is due to friction.

B. Inertia resist changes to the state of motion of a body.

Explanation:

The force of inertia is an inherent property of matter in which it allows a body to resist changes to the state of motion of the body.

According to Newton's first law of motion "a body will remain at rest or in constant motion unless if an external force acts on it".

This is the law inertia.

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
