A solenoid 0.425 m long has 950 turns of wire. What is the magnetic field in the center of the solenoid when it carries a curren t of 2.75 A? (JC 19.57)
1 answer:
Answer:
The magnetic field in the center of the solenoid is .
Explanation:
Given that,
Length of solenoid = 0.425 m
Number of turns N = 950
Current I = 2.75 A
The magnetic field in the center of the solenoid is the product of the current , number of turns per unit length and permeability.
In mathematical form,
Where,
N = number of turns
L = length
I = current
Now, The magnetic field
Put the value into the formula
Hence, The magnetic field in the center of the solenoid is .

Answer:
radiation!
Explanation:
Answer:
v= s/t
Explanation:
250 km/ h =69.44m/s
S1=2 times 69.44 ≈ 139m
Next 2.5 seconds:
S2 = 100m
Average speed:
v=139m+100m/2s+2.5s = 239/4.5s = 53.2 m/s=192km/h
