Answer:
I = 578A
Explanation:
The magnitude of the peak value of the induced current flowing in a coild is given by


Where
I= current
N = Number of loops
angular velocity
R= Resistance
B = Magnetic field
A = Area
Replacing our values we have that,


Answer: 800
Explanation:
1/2 x m x v^2 = m x g x h
KE = 10 x 10 x 8
KE= 800
The kenitc energy of the bullet lowers as it keeps going up.
Because gravity is pushing the bullet down as the bullet goes up.
I'm pretty sure that the way to put this answer.
