In the amusement park ride known as Magic Mountain Superman, powerful magnets accelerate a car and its riders from rest to 43.4
Anton [14]

Answer:

Average net force, F = 15157.15 N

Explanation:

It is given that,

The mass of the car and riders is, m=3\times 10^3\ kg

Initial speed of the car, u = 0

Final speed of the car, v = 43.4 m/s

Time, t = 8.59 seconds

We need to find the  average net force exerted on the car and riders by the magnets. It can be calculated using second law of motion as :

F = m a

F=m(\dfrac{v-u}{t})

F=3\times 10^3\ kg\times (\dfrac{43.4\ m/s-0}{8.59\ s})

F = 15157.15 N

So, the average net force exerted on the car and riders by the magnets. Hence, this is the required solution.

What device produces light by running an electric current through a gas
Andrej [43]

Answer:

fluorescent bulb

Explanation:

A fluorescent bulb is what produces light.

It produces light by passing electric current through a gas to

A fluorescent lamp, is a low-pressure mercury vapor and a gas-discharge lamp that uses fluorescence to produce visible light. like the ones we see.  An electric current in the gas excites mercury vapor, and that produces a short wave ultraviolet light and well that causes a phosphor coating on the inside of the lamp to glow. i tried making this sound as simple as possible.

i hope this really helps you !! thanks this and mark this as brainliest !!!
