A block is released from rest, at a height h, and allowed to slide down an inclined plane.
There is friction on the plane. At the bottom
of the plane, there is a spring that the block
will compress. After compressing the spring,
the block will slide up the plane to some maxi-
mum height, ha, after which it will again slide
back down.
How much work is done on the block be-
tween its release at height h and its ascent to
its next maximum height?

its c its is a mixture of gases

if you answer my question i will answer yours

radiation warms things up temp rises convection currents air circ windy weather

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
