Answer:
Explanation:
given,
diameter of merry - go - round = 2.40 m
moment of inertia = I = 356 kg∙m²
speed of the merry- go-round = 1.80 rad/s
mass of child = 25 kg
initial angular momentum of the system
final angular momentum of the system
from conservation of angular momentum
Answer: Height should be 44.1 m.
Explanation:
Pressure exerted by stationary water stored at a height is,
P = ρgh
4.41 × 
= 1000× 10× h
solving we get,
h = 44.1 m
Answer:
Explanation:
The theory of propagation of error in case of addition and subtraction states that maximum errors are added in absolute terms in both the operation of addition and subtraction . So in this case the subtracted value will be
10.5775 - 10.3005
= .2770 g
errors will be added ie in subtracted value we can find error to the tune of
.0002 + .0002 = .0004 g
So the subtracted value will be written as
.2770 ± .0004
