A gas undergoes two processes. In the first, the volume remains constant at 0.230m3 and the pressure increases from 3.00×105Pa to 5.50×105Pa . The second process is a compression to a volume of 9.00×10?2m3 at a constant pressure of 5.50×105Pa .
Find the total work done by the gas during both processes.
A startled armadillo leaps upward rising 0.550 m in the first 0.203 is. (a) What is its initial speed as it leaves the ground? m/s (b) What is its speed at the height of 0.550 m? m/s (c) How much higher does it go?
At this time it has reached a height of 420 metres above launch pad and attained an upward velocity of 50 ms-1. From this time on, the rocket has constant upward acceleration -10 ms-2 (due to the effect of gravity alone).
