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

Explanation:
Using kinematics,
t = 10s
v = 0m/s
a = -9.8m/s^2
Therefore u = v - at = 0 - (-9.8)(10) = 98m/s.
Answer:
w = 6.325 rad/s
Explanation:
Given the following data;
Mass = 2kg
Radius, r = 10m
Centripetal force = 800N
To find the angular velocity of the car;
First of all, we would use the following formula to solve for the speed of the car;
Centripetal force = mv²/r
800 = 2*v²/10
Cross-multiplying, we have;
8000 = 2v²
4000 = v²
Taking the square root of both sides, we have;
v = √4000
v = 63.25 m/s
Next, we find the angular velocity, w using the formula below;
w = v/r
w = 63.25/10
w = 6.325 rad/s
