Explanation:
When the wire is connected to a battery, the compass needle moves and changes its position. This happens because the needle magnetizes the copper wire, thus, creating a force.
While the current in the wire produces a magnetic field and exerts a force on the needle. The insulation on the wire becomes energized and exerts a force on the needle. Hence, the compass needle moves and changes its position.
Why is it always balloons?
anyways so the balloon volume goes somewhere else when it shrinks because the balloon is losing air i think
Answer:
40,000N
Explanation:
Force = Acceleration × Mass
2000×20=40,000
26.82m/s
Explanation:
Given:
speed = 60mph
problem: convert to m/s
To solve this problem, we have to find the right and appropriate conversion factor which equals to 1 to multiply this unit with:
we are converting:
miles to meters
hours to seconds
1.609km = 1mile
1000m = 1km
60s = 1 min
60 min = 1hr
Now to convert from mph to m/s
60 x 
x 
= 26.82m/s
