Aforce does work on a 50 g particle as the particle moves along the following straight paths in the xy-plane: 25 j from (0 m, 0 m) to (5 m, 0 m); 35 j from (0 m, 0 m) to (0 m, 5 m); -5 j from (5 m, 0 m) to (5 m, 5 m); -15 j from (0 m, 5 m) to (5 m, 5 m); and 20 j from (0 m, 0 m) to (5 m, 5 m).
is this a conservative force?
if the zero of potential energy is at the origin, what is the potential energy at (5m, 5m)?
yes that is true good luck
the train flies 350 miles in the first hour, another 350 miles in the 2nd hour, and a final 350 miles in the 3rd hour.
the total distance covered is (350 + 350 + 350) = 1,030 miles
all i can say is: that i would like to see !
answer : (c) 0.12 c°
it is given that all the gravitational potential energy is converted to thermal energy.
so, the thermal energy is balanced by gravitational potential energy.
gravitational potential energy,
and amount of heat is,
where, c is specific heat.
hence, this is the required solution.
correct option is (c) 0.12 c°.
