Using Vp/Vs=Np/Ns, we can rearrange to get Ns= (VsNp)/VpSo, Ns = 8*50/4=100 turns.
Resolve the vertical velocity of the projectile (25sin42) and use v=u+at where v=-25sin42m/s, u=25sin42m/s, a=-9.8m/s/s to find t. t= (50sin42)/9.8= 3.41sResolve horizontal velocity (25cos42) and multiply...
Work done= F x d; where d= distance object has been moved through in same direction of force and F= resultant force. F=8 N.d=2 x 1000 m.WD = 2000 x 8 = 16000 J
The current is the number of electrons flowing through the wire per second. The voltage however, is the amount of energy each individual electron is carrying as it moves through the wire.
Energy used for one boil = (3.78 x 105 / 100) x 55Energy used for one boil = 2.079 x 105 J Energy lost per boil = 3.78 x 105 -2.079 x 105Energy lost per boil = ...
