How does a material get a negative charge?

Answers

Explanation:

When insulating materials rub against each other, they may become electrically charged . Electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. The material that gains electrons becomes negatively charged. The material that loses electrons is left with a positive charge.

What force is necessary to accelerate a 1,200 kg car at a rate of 35 m/s2?
How much acceleration would the car have if a 30,600 N force was applied to
the car?

Answers

Explanation:

Given that,

Mass of a car, m = 1200 kg

Acceleration of the car, a = 35 m/s²

The force acting on the car is given by :

F = ma

F = 1200 kg × 35 m/s²

= 42000  N

If the force is 30,600 N, then acecleration is given by :

[tex]a=\dfrac{F}{m}\\\\a=\dfrac{30600}{1200}\\\\a=25.5\ m/s^2[/tex]

Hence, this is the required solution.

6. A car is driving in a large circle at a constant speed of 20 miles per hour. Is the car accelerating? How do you know?​

Answers

The car is not accelerating, because the car is driving at a constant speed of 20 miles per hour.

The car is NOT accelerating. An object cannot accelerate if it has a CONSTANT speed. Acceleration is the rate of change of velocity, meaning that it has to change speeds as it moves.
