The tilt can lead to darkness, for the sun is away from the Earth. The sun will reach the Earth at different times, and if it is further away, it will cause the temperature to change.
The change in the internal energy of the gas during the process is 25 J.
Explanation:
In an adiabatic process, no heat is gained or lost by the system. According to the first law of thermodynamics,
Q= dU + dW
Here, Q is heat gained or lost by the system,
dU is the change in the internal energy of the system,
dW is the work done,
As the process is adiabatic, Q=0 we get,
dU= ₋ dW = ₋ 25 J
The negative sign shows that there is a decrease in the temperature of the system.
Answer:
Acceleration is zero
Explanation:
if the acceleration is zero, then the velocity-time graph is a horizontal line (i.e., the slope is zero). If the acceleration is positive, then the line is an upward sloping line (i.e., the slope is positive).
