#1). Anthony does the same amount of work as Angel, with <em>more power</em>.
#2). Power = (Work)/(Time) = 41,000 J / 500 s = <em>82 watts .</em>
#3). Power = (Work) / (Time) = 83 J / 3 sec = <em>27.7 watts</em>
Answer:
<h2>
Work done by the gas is given as</h2><h2>

</h2>
Explanation:
As we know that the process is isothermal so here work done is given as

here we know that


now we have

so we have

A. 90km/h = 25 m/s
W=1/2mv^2
=1/2* 650* 25^2
= 203125(J)
b. v’= 90-50= 40km/h
= 100/9 m/s
W=1/2mv^2
=1/2*650*(100/9)^2
= 40123,45679
Answer:
- The displacement is 33.2 cm in direction to the joint.
Explanation:
The displacement can be obtained as the vector pointing from the starting position to the final position. The nearby joint give us an frame of reference. Putting the starting of the coordinate system at the nearby joint, the vector for the starting position is:

where
is the unit vector pointing from this position to the joint. The final position is:
.
So, the displacement vector
will be




This is 33.2 cm pointing to the joint.
