Answer:
The number of turns in the solenoid is 230.
Explanation:
Given that,
Rate of change of current, 
Induced emf, 
Current, I = 1.5 A
Magnetic flux, 
The induced emf through the solenoid is given by :
or
........(1)
The self inductance of the solenoid is given by :
.........(2)
From equation (1) and (2) we get :
N is the number of turns in the solenoid
N = 229.28 turns
or
N = 230 turns
So, the number of turns in the solenoid is 230. Hence, this is the required solution.
$10.50
You would set up a proportion to get the answer. X 5
=
10 100
Then cross multiply
50=100x
Lastly divide to get the x by it’s self.
50/100=0.50
100\100=1
X=0.50$
10+0.50=$10.50
Both will hit the ground at the same time because their initial vertical velocity is the same and they are accelerating downward at the same rate (-9.8 m/s^s). Ball A will travel further because it has a greater horizontal velocity and both balls have a horizontal acceleration of 0. Their horizontal velocity will remain contestant and they will travel for the same amount of time. The if t is constant and the v of ball A is greater then D will be greater in the equation
D (distance) = vt+1/2•a•t^2
