Answer:
The number of turns in the solenoid is 22366.
Explanation:
The number of turns in the solenoid can be found using the following equation:

Where:
B: is the magnetic field = 8.90 T
L: is the solenoid's length = 0.300 m
N: is the number of turns =?
I: is the current = 95 A
μ₀: is the magnetic constant = 4π×10⁻⁷ H/m
By solving equation (1) for N we have:

Therefore, the number of turns in the solenoid is 22366.
I hope it helps you!
Answer: 6000N/m^2
Explanation:
Weight =1500N
Area =0.5m^2
Pressure =1500/(0.5^2)
=6000N/m^2
Note: Newton is denoted by 'N' (Capital) and use '^' for powers.
Answer:
c is the answer because it i in a series not a parallel circut.
Explanation:
I believe it would be 3 amps.
