B) 7.87 m/s
The gravitational pull is the rate of change of velocity which is the acceleration. Formula for acceleration is;
Given:
• Initial velocity = 0m/s; I dropped the ball, and didn't throw it, so it was at rest firstly
• Time taken = 2.40s
• Acceleration = 3.28m/s^2
We're require to find the final velocity, at which the ball hit the ground with. Ignoring air resistance, keep in mind that the velocity of an object increases as it comes closer to the ground.

Answer:
The pressure is
Explanation:
From the question we are told that
The initial pressure is
The temperature is
Let the first volume be Then the final volume will be
Generally for a diatomic gas
Here r is the radius of the molecules which is mathematically represented as
Where are the molar specific heat of a gas at constant pressure and the molar specific heat of a gas at constant volume with values
