Answer:
The answer would be A. - the temperature remains constant
Explanation:
An isothermal process is a change of a system, in which the temperature remains constant: ΔT = 0
Answer:
c. 40200 J
Explanation:
Assume gravitational constant g = 9.8m/s2. The weight of the 2000kg vehicle is
In addition to the friction averaging at 500N, the total force is
F = 20000 + 500 = 20100 N
The work required to generate this force over a distance of 2m would be
F*s = 20500 * 2 = 40200 J
So c.40200 J is the correct answer
Answer:
The maximum height of the ball will be "16.53 m".
Explanation:
Given that,
As we know,
The initial as well the final height on the ball will be same after it reaches it's maximum height.
then,
⇒
where,
hence,
The max height of the ball will be:
⇒
