Why is there a difference in how bright the light bulbs are when we connect light bulbs in a series versus parallel?
If the two bulbs are in parallel, the electrons only have to go through one light
bulb, so there is less resistance.
The extra wire in the parallel circuit makes it easier for electricity to flow.
The electrons move more slowly in a parallel circuit due to the extra wire.
If there are two light bulbs in series, there is less resistance, so the electrons
move faster.

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.

The magnets are probably damaged or there not strong enough to attached to the refrigerator

The answer would be a
