Answer:
mechanical thermal chemical
Explanation: because you use mechanical energy to turn it on
Evaporation? im not positive but im almost certain that's the answer
Explanation:
a) It will weigh less because of its distance from the block.
b) torque = W1×d1 = (10N)(0.25m) = 2.5 N-m
c) torque = W2×d2 = W2×(0.50m)
d) W2×d2 = W1×d1
W2 = (d1/d2)W1
= 5 N
