Answer:
Explanation:
Length of bar = L
mass of bar = M
mass of each ball = m
Moment of inertia of the bar about its centre perpendicular to its plane is
Moment of inertia of the two small balls about the centre of the bar perpendicular to its plane is
Total moment of inertia of the system about the centre of the bar perpendicular to its plane is
I = I1 + I2
Answer:
7.481W
Explanation:
power= work done÷time
power= force × uniform velocity
a= ∆v/t
29.0ms=
=(0.72-0)÷29×10^-3
a=24.83m/s^2
Newton's second law
f=ma
=(0.84×24.83)
=20.86N
w=FD
v^2=u^2+2as
0.5184=0+49.66s
s=0.0104m
20.86×0.0104
=0.216944J
0.216944÷t
P=7.481W
Im afraid i cant help u if we can’t see the image u r working with. could u provide an image of the question?
A black hole is a cosmological object that is created when a massive star comes to the end of its life and collapses under its own gravity. Black holes have massive gravitational fields that even light cannot escape beyond a certain distance. Before being engulfed, matter that is pulled into a black hole should become very hot and emit electromagnetic radiation.
Answer:
C) either of these depending on speed
Explanation:
In classical mechanics, the momentum of a body is defined as the product of its mass and its velocity at a given time. Although the bullet has a smaller mass than the container ship, its momentum may be greater or lesser than container ship's, depending on its speed.
