Answer:

Motors commonly contain a "commutator" which allows a magnetic field due to a loop of wire to always be in a say "clockwise or counterclockwise" direction even tho the loop of wire is rotating.

That means that magnetic field due to the surrounding magnets is always in the same direction, but the magnetic field due to the rotating   loop of wire is continually changing so that it will always oppose the surrounding field which remains in a constant direction.

This is most easily seen in a "DC - direct current motor".

1. Calculate the velocity of a 0.8 kg kitten with a forward momentum of 5 kg*m/s.
hichkok12 [17]

Q.1

Answer . Momentum = mass x velocity

               Momentum/mass = velocity

               5/0.8 = velocity

               6.25 m/s = velocity

Q.2

Answer . F = ma => a = f/m => a = 7/3.2 => a = 2.1875m/s²

Superguy is flying at treetop level near Paris when he sees the Eiffel Tower elevator start to fall (the cable snapped). His x-r
brilliants [131]

If the elevator falls from a height of 240 meters and Superguy is 1 km away, he will have 6.5 seconds to save Lois, which means that his average speed must be 150 meters per second.

<h3>What is the average speed?</h3>

The total distance traveled by an object divided by the total time taken is the average speed.

The average speed of an object indicates the pace at which it will traverse a distance. The metric unit of speed is the meter per second.

Given data:

Distance of super guy from the tower = 1.00 km

height(h)= 240 m

From the Newtons' second equation of motion:

\rm S= ut+\frac{1}{2} at^2 \\\\\ 210 = 0+\frac{10}{2} t^2 \\\\ t= \sqrt 42\\\\t=6.5 \ sec

Distance is the foundation as the product the velocity and time;

D=ut

u=d/t

u=1000/t

u=1000/6.5

u=150 m/sec

Hence, he will have 6.5 seconds to save Lois, which means that his average speed must be 150 meters per second.
