explain why if charge cannot be created or destroyed, electrically neutral objects can become electrically charged

1 answer:

5 0

Charge is actually either excessive number or electrons or shortage of them.
as you can't destroy the electron or create it - you can't destroy or create charge

A solid element that is malleable' a good conductor of electricity, and reacts with oxygen is classified as a

Finger [1]

1) metal
Even though metalloids are also conductors of heat and electricity, malleable they are not as good as metals.
Metals are very good conductors of electricity and heat. They are also very hard to touch. Noble gases and non metals are the exact opposite in physical and chemical properties. Metals readily react with oxygen.

Given parameters:

Mass of the body = 200g

Force on the body = 10N

Unknown parameters:

Acceleration produced by the force = ?

To solve this problem we must first define force in terms of mass and acceleration. This is possible due to the Newton's first law of motion.

Force = mass x acceleration

Here the unknown is acceleration and we can easily solve for it.

But we must take the mass to kilogram in order for it to cancel out.

1000g = 1 kg

200g = x kg = $\frac{200}{1000}$ = 0.2kg

Now input the parameters and solve;

10 = 0.2 x acceleration

Acceleration = $\frac{10}{0.2}$ = 50m/s²

The acceleration produced by the body is 50m/s²
