C. Both A. and B.
Explanation:
Statement A. Reducing the volume is true because of Boyle's law, which states that for a gas at fixed temperature, the pressure p and the volume V are inversely proportional:
Therefore, when the volume V is reduced, the pressure p increases.
Statement B. Adding more gas is also true: in fact, if we add gas into the container, we will have more molecules of the gas hitting the wall of the container. But the pressure of a gas is exactly given by this: by the collision of the molecules against the wall of the container, so the more the molecules of gas, the greater the pressure.
Answer:
Explanation:
Given
speed of Electron
final speed of Electron
distance traveled
using equation of motion
where v=Final velocity
u=initial velocity
a=acceleration
s=displacement
acceleration is given by
where q=charge of electron
m=mass of electron
E=electric Field strength
Answer:
Increasing the length of the pendulum quantitatively increases the time period of oscillation.
Explanation:
Given data,
A grandfather's clock keeps time by making 60 swings in 60 seconds.
After two hours the clock is slow by 1.5 minutes.
The time period of oscillation is given by the formula,
<em> </em>
Where 'l' is the length of the pendulum clock.
Increasing the length of the pendulum quantitatively increases the time period of oscillation.
Answer:
The Gravitational force is the answer.
Im pretty sure it’s a because it makes more sense you know?.
