It runs slower <span>as gravity is lower so acceleration due to gravity is smaller</span>
Solutions are basically a release from a problem. This is more than helpful.
Since there is no decimal point in the number given above, the counting for the number of the significant figures will start from the left. Then, the first zero from the left is insignificant. Therefore, in this number there are 6 significant figures.
Answer:
Wegener proposed his theory of "continental drift." Wegener proposed that the continents plowed through crust of ocean basins, which would explain why the outlines
Answer
given,
mass of disk = 2 Kg
radius = 0.1 m
time = 10 sec
a) 800 rpm to rad/s
=
=
b) 740 rpm to rad/s
=
=
c) Angular acceleration
d) moment of inertia of disc
I = 0.01 Kg.m²
e) τ = I α
τ = 0.01 x 0.629
τ = 6.29 x 10⁻³ N.m
f) impulse = Force x time
J = 0.629 Ns
g) Work done
W = Δ KE
W = 5.07 J
