Answer:
the gas does no work.
Explanation:
An isochoric process is a process in which the volume of a gas is kept constant.
The work done by a gas during a transformation is given by:
where
p is the gas pressure
is the change in volume of the gas
For an isochoric process, the volume of the gas does not change, so
and so, according to the previous equation, the work done by the gas is zero:
W = 0
Answer:
The value is 
Explanation:
From the question we are told that
The mass of the Ping-Pong is 
The terminal speed is 
The drag force is 
Generally the resultant force on the Ping- Pong is mathematically represented as
when terminal velocity is attained , the resultant force is zero so
=> 
=> 
=>
Answer:
average velocity = displacement/time
The jet stream winds blow storms from west to east
