Answer:
K'=4K
Explanation:
The electric potential energy is given by :
Where
k is spring constant
x is compression or extension in the spring
If the displacement of a horizontal mass-spring system is doubled, x'= 2x
New elastic potential energy :
So, new elastic potential energy 4 times the initial elastic potential energy.
Answer:
The tendency of undisturbed objects to stay at rest or to keep moving with the same velocity is called inertia. This is why, the first law of motion is also known as the law of inertia.
<em><u>Example</u></em><em><u>.: A ball at rest on the ground continues to be at rest unless someone kicks it or any external force acts on it.</u></em>

<span>One half-life produces (1/2) of the decaying substance.
There would still be 48 atoms. But 24 would have thrown off
particles from their nucleuses, and only 24 would still be radioactive.</span>
Answer:
If the Kelvin temperature of a gas is increased, the volume of the gas increases. This can be understood by imagining the particles of gas in the container moving with a greater energy when the temperature is increased.
Explanation:
If you heat a gas you give the molecules more energy so they move faster. This means more impacts on the walls of the container and an increase in the pressure. Conversely if you cool the molecules down they will slow and the pressure will be decreased.
To calculate a change in pressure or temperature using Gay Lussac's Law.
Explanation:
According to newtons first law of motion:
'' a body will continue in its state of rest or uniform motion along a path unless it is acted upon by an external force".
A body in equilibrium that is floating will be stable and not move in any direction. Even if it moves, the motion will be constant wouldn't change.
- To move the body in any direction, one has to swim.
- Swimming is the application of an external force to counter the balanced forces at equilibrium on a body.
- This works when the net external force is greater than that the balanced forces.
