Yes the Earth is bigger than the Moon.
The moon is one-quarter the size of Earth.
Answer:
d
a balanced force acted on it and propelled it to 4,000 km/hr
Explanation:
For the neutrons star which is moving in outer space at 4,000 km/hr, it could only be possible as a result of the balanced force which had already acted on it. <em>This is based on newton's law of motion which states that 'To every action, there is equal and opposite reaction'. </em>
AC (Alternating Current) generator is a device that produces an electromotive force.This generator produces alternating current. Alternating current is electric current that changes its direction many times a second, at regular intervals. This is the type of current with which customers are supplied in the energy distribution network.
The angles of incidence with respect to the normal will the x-rays reflect from the crystal will be
16.60 degrees. Given: wavelength of X-rays, λ= 0.120 nm
Distance, d=0.21 nm
According to Bragg’s diffraction law: nλ = 2dsinθ
thus, 0.120 = 2*0.21sinθ
or θ = 
(0.120/2*0.21)
or θ = 16.60 degrees.
