Answer:
a) 104
b) 106
c) 884 mA
Explanation:
The ratio of the transformer is given by:
We need to know the current in the primary in order to obtain the power applied.
The current rating of the fuse is the current on the primary, 884mA as we calculated before in order to obtain the power.
Answer:
A.) the magnet or coil moves faster. Mark me brainliest <3
Explanation:
Answer:
Explanation:
Since the block is at rest in an elevated position, we can assume that it only has potential energy.
U=mgh is the formula for potential energy where U=potential energy, m= mass, g=acceleration due to gravity, and h=height.
Plug in known variables....
U=4kg*9.8m/s^2*20m
U=784 joules of potential energy or letter A.
the answer is c because it has the most volts
a
1. Is A. at the poles because thats where the magnetic field is going out then coming back into the earth to produce the magnetic field.
2. Again its A. because the compass needle is attracted to " north " which is magnetic south. It does this because opposites attract.
3. This one would be B. Because if the magnets were being repelled the magnetic field lines would look like there was a line that the field hit and bounced off of it.
4. This answer is A. the magnetite helps them migrate so they know which way is north and which way is south.
5. This answer is A. Because without the domains there wouldn't be poles on the magnetic object. <span />
