Mass x Force of gravity = Weight
Weight is a force.
On Earth, the force due to gravity is ~9.81 N/Kg. So an object of 100 Kg will have a weight of ~981 N
R= (rou * L) / area
where R is the wire resistance
rou: resistivity of the wire material
L : wire length
A : cross section area of wire
by sub.
0.757= (rou*25)/ 3.5*10^-6
25*rou = 2.6495*10^-6
rou= 1.0598*10^-7 ohm.m
Answer:
95.38 %
Explanation:
Transformer is an electrical device which has two or more coils of wire used to transfer electrical energy by changing magnetic field
Power of a transformer coil = voltage * Current
Transformer does not require any moving parts to transfer energy. Therefore we cannot see any friction or windage losses here. But they have some types of losses called “copper losses” and “iron losses” but generally these are quite small.
So there for it can affect the efficiency of the transformer also. Efficiency can be defined as follow
hi friend the earth spin at 1,000 in meters per hour
I hope it helped you
Yes, the water in the cup have the same average kinetic energy as the ocean, because I focus on the word 'average'. However the cup of water have less INTERNAL energy than the ocean.
