Answer:
Here magnetic field at center does not change, it remains constant .
Explanation:
The magnetic field at the center of the solenoid depends on only the current flowing through the wire and the number of turns of the coil around the solenoid .
Since magnetic field at the center of the solenoid is given by the expression
Here is permeability constant whose value is equal to .
N is number of turns of the coil .
I is current flowing through the coil .
The field lines near the center of the solenoid are approximately parallel , indicating a nearly uniform magnetic field.
Answer:
the answer is the spinning of the moon lets us see different amounts of light
Explanation:
you wanna know why uh yes ok lets cut to the magic so when the moon.
Answer:
20 N up
Explanation:
Since the object on the floor is sitting still. Based on Newton's law of force. Objects must have equal reaction and force against each other for still objects. So the answer is 20 N up. Since the force are equal on both sides making the object not moving.
P=W/t=2940/10=294 W
W=F•s
W=m•g•s
W=150×9.8×2
W=2940 J
It takes sunlight 8 minutes to reach earth , so yes
