Ответ:
2.5 m/s²
Explanation:
You can solve the following equation: F=ma for acceleration.
You'll be left with this:
a=F/m
And then you substitute the force and the doubled mass
a=500N/200kg
a=2.5 m/s²
Ответ:
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
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
