<h2>From kinetic theory of gases, the pressure exerted by a gas is given by velocity of gas molecules. m = Mass of each molecule of a gas. But by assumptions of the kinetic theory of gases the average kinetic energy of a molecule is constant at a constant temperature.</h2>
Answer:
Part(a): The required change in angular displacement will be .
Part(b): The angular displacement will be increased by a factor of 2.
Explanation:
If , , and represents the initial angular velocity, the final angular velocity , the angular acceleration and the change of angular displacement s, then from angular kinematic equation, we can write
Part(a):
Given, , and . Substituting ll the values in the above equation, we have
So the angle through which the parts rotates before reaching the final speed is .
Part(b):
Given, , and . So,
Therefore, the angular displacement will be changes by a factor of 2.
The specific heat of a metal or any element or compound can be determined using the formula Cp = delta H / delta T / mass. delta pertains to change. That is change in enthalpy and change in temperature. From the given data, Cp is equal to 343 cal per (86-19) c per 55 grams. This is equal to 0.093 cal / g deg. Celsius
Answer:
50.0543248872 ft
Explanation:
F = Load = 20 ton =
d = Diameter = 1.25 in
= Initial length = 50 ft
= Final length
A = Area =
Y = Young's modulus =
Young's modulus is given by
The length during the lift is 50.0543248872 ft
