Answer:
restoring force is 2 N
Explanation:
given data
angle pulled = 5°
force = 1 N
pulled = 10°
to find out
restoring force
solution
we know here force
force = m×g×sinθ ..........1
so here θ is very small so sinθ = θ
1 = mg(5)
mg = 1 /5 ..................2
and
now for 10 degree
we know here θ is small so sinθ = θ
so from equation 1
force = m×g×sinθ
put equation 2 here
force = 1/5 × 10
force = 2 N
so restoring force is 2 N
Answer:
C. the net force on the object
Explanation:
That is because Force= mass x acceleration. The question says that we know the mass and acceleration, which means that it would be the force that resulted in the acceleration of the mass.
Zinc plate used in the simple cell is not pure so impurities present in it provides a conducting path for the flow of charge. This makes zinc wasted. It is called the local action. It can be removed by using pure zinc or amalgamated zinc rod.
