Answer:
Explanation:
Given
Orbital speed is v
Mass of planet is m
Radius of circular orbit is r
suppose M is the mas of satellite then centripetal force on satellite is equal to the Gravitational Pull.
where G=gravitational constant
thus on solving we get
Answer:
The component of waves must have same frequency and phase.
Explanation:
when the component of waves vibrate at the same rate and attain maximum point at the same time, reinforcement of the waves amplitude occur to cause a constructive interference.However, when the two waves are out of phase where one is at minimum when the other is at maximum a destructive interference happens.
Momentum of the bullet is m×v = 0.01 kg × 800 m/s = 8 kgm/s
so momentum of baseball also= 8 kgm/s
8= mass of baseball × velocity
8= 0.145 × v
on solving for v,
v= 55.17 m/s which is the required velocity

To develop this problem we must apply the concepts related to the Ampere Law. The line integral of B.ds around any closed path is equal to the current permeability constant, this current for the particular case passes through the 'internal' surface delimited by the closed path.
Ampere laws is defined as,
The radius of the circle is r, so if
r < R
And there is no current inside so ,
Therefore the magnetic field inside the wall is Zero.
Answer:
A conversion factor is an expression for the relationship between units that is used to change the units of a measured quantity without changing the value. A conversion ratio (or unit factor) always equals one (1), where the numerator and the denominator have the same value expressed in different units.
