Explanation:
Inertia is a physical quantity that expresses the tendency of body to be in a state of rest or continue with uniform motion along a straight path.
- Newton's first law of motion is famed as the law of inertia.
- The law states that "an object will continue in a state of rest or along a path with uniform motion unless acted upon by an external force".
- The reluctance of a body to change its state is simply inertia.
Inertia of a body is function of the innate force it possesses that helps its to resist change.
Inertia is often a function of the mass or the amount of substance it contains.
Sentence use:
Despite the raging storm the rock boulder remain fixed due to a high inertia.

Answer:
V= 4999.5 m/s
Explanation:
Given that
mass ,m= 605 gm
Length ,L= 0.75 m
width ,b= 0.01 m
height ,h= 0.03 m
frequency ,f= 3333 Hz
We know that
2 Length = Wavelength
λ= 2 x L
λ = 2 x 0.75 m
λ= 1.5 m
The speed V
V= f x λ
Now by putting the values
V= f x λ
V= 3333 x 1.5 m/s
V= 4999.5 m/s
I think the answer should be c. vaporizing

From the question we are told that
The length of the solenoid is
The number of turns is
The magnetic field of the earth is
Gnerally magnetic field is mathematically represented as

A nucleus undergoing radioactive decay means that this nucleus is relatively large and contains many neutrons leading to instability in the naturally occurring state.
Therefore, this large nucleus emits radiations in the form of alpha, gamma or beta particles. During this process, the nucleus is actually emitting a part of itself in order to reach a more stable element.
Example:
carbon-14 emits radiations and decays forming nitrogen.
