We can solve the problem by using the first law of thermodynamics:
where
is the variation of internal energy of the system
Q is the heat added to the system
W is the work done by the system
In this problem, the variation of internal energy of the system is
While the heat added to the system is
therefore, the work done by the system is
Answer:
33.73 lb to the left
Explanation:
You need to exert a force with the same magnitude, but opposite direction. You can visualize it in this way: When you push an object, the object will follow your path, but if there is another person opposing the force you are exerting, the object will just not move. If the force that the other person exerts were higher, then the object would move in the opposite direction. So, you need them to have the same magnitude.
Answer:
Discrimination
Explanation:
As a society, there are people who treat men different from women. Back in time, men got paid more. Men were more likely to get a job.
a = ( v(2) - v(1) ) ÷ ( t(2) - t(1) )
2 = ( v(2) - 10 ) ÷ ( 6 - 0 )
2 × 6 = v(2) - 10
v(2) = 12 + 10
v(2) = 22 m/s
