Answer:
Explanation:
Acceleration of gravity on the surface of
Neptune is given
g' = G M/R^2,
where M is the planet's mass.
M g' will be the apparent weight registed at the poles.
G is the universal constant of gravity
The "apparent weight" at the equator will be
reduced from M g' by the centripetal force M
R w^2, where w is the rotational angular
velocity in radians/s), which you can deduce
from the 16 hour length of a day.
<h2>The option ( b ) is appropriate answer </h2>
Explanation:
When a projectile is projected from height horizontally . The only force acting upon it is the downwards gravitational force of attraction due to earth .
Due to this force its vertical component of velocity , which is in the downward direction will be increased .
As there is no force horizontally , the horizontal velocity of throw will remain constant .
Thus ( b ) option is the correct option .
Answer:
Explanation:
As we know that current density is ratio of current and area of the crossection
now we have
so the current through the wire is given as
now we have
here we have
now plug in the values in above equation
now we have
now plug in both limits as mentioned
here R = 2.11 mm
B low frequency it is the lowest frequency
Density is varying through the world’s oceans. The density of ocean water is not uniform.
