No, it will not fall. The pencil will remain at zero speed relative to the spacecraft and will orbit the earth with the spacecraft.
Answer:
Explanation:
As we know that at isochoric conditions if pressure of the gas is tripled then the temperature also becomes 3 times
So heat given in this process is given as
Now it is expanded to initial pressure again by adiabatic process
So in this part there is no heat exchange
Also we know that
Now in the last process we compressed the gas to original volume
Now total heat in the process is given as
Answer:
SI is used in most places around the world, so our use of it allows scientists from disparate regions to use a single standard in communicating scientific data without vocabulary confusion
Answer: 1224 joules
Explanation:
Given variables are:
Power (p) = 68 W
Time taken (t) = 18 seconds
work done (w) = ?
Recall that power is the rate of work done per unit time i.e Power is obtained by dividing the work done by the time taken.
Hence, Power = work / time
Make work the subject formula
work = power x time
work = 68 watts x 18 seconds
work = 1224 joules
Thus, 1224 joules of work is done.
