sorry it is 2kVA

I have a generator. Single phase 220 volt A.C output Frequency 50 Hz 2000 kVA Rotor winding of my generator was burnt. It was rewinded but it burnt again after 1 day. There are 2 types of windings in stator one main winding which gives 220 volt A.C output and 2nd is excitation winding...

Why gravity follows inverse square law? How Einstein explained it? Can someone explain it please?

s=diameter=2.50 m r=distance of moon from earth=3.8x10^8 theta=s/r theta=2.50/3.8x10^8 = 6.6x10^-9 rad I got the correct answer but I am confuse about diameter that how it can be taken as "s"? Kindly explain.

Homework Statement A tiny laser beam is directed from Earth to moon. If beam's diameter is 2.50 m at the moon, how small much the divergence angle be for the beam? The distance of moon from the Earth is 3.8x10^8 m Homework Equations The Attempt at a Solution

When a body is fired upward with escape V (i.e 11.2 km/s) then what will be the height when the body leaves the gravitational field? I found by using formula 2gh=Vf^2 - Vi^2 keeping vf= 0 and vi=11200m/s then I got h=6400km= radius of the earth. Is it range of the gravitational field?

But artificial gravity is provided in gravity free space satellite to increase the efficiency of the persons inside. It means they moves very slow in G. free space, and clock too? Does vibration of cesium atom also change?

Can gravitational field strength cause time dilation. as G.F.S on Earth is 10 N/kg and on moon it is 1.6 N/kg. so will a clock on the moon surface tick slowly for the observer on Earth or not?

Case 1 In 2D coordinate system the sum of the angles of all quadrants=360 degree in (x,y) plane Case 2 In 3D coordinate system (x,y,z) I took 3 possible planes i.e. (x,y) (y,z) (x,z) each plane provides angle of 360 degree, so can we say that in 3D coordinate system sum of all...
