When I drop a bouncy ball it bounces back up to me. What force causes it to bounce?

I do not think that there is a "force" that causes it to bounce. it's the rubber (or whatever material) makes up the ball.

Gravity pulls the ball down to the centre of the Earth but the ground resists the ball in the opposite direction. If there was no resistance the ball would phase through the ground. This is Newton's Second Law. However since the ball is made of rubber (just an assumption), the force of the floor resisting the ball is higher than the force of gravity, hence the ball then flies back up.

Is this a multiple choice question?
If not, well then the answer is that the volcano sort of sinks into the ground. Like it sort of subducts.
Hope this helped!!!:)

In a elastic lab what did you change and why?

Vilka [71]

I changed my undershorts. The elastic on the old ones I put on that day was deteriorated, and it completely failed when I dripped lab coffee on it, causing falldown.

If two charged objects in a laboratory are brought to a distance of 0.22 meters away from each other. What is

zysi [14]

Answer:

$q_2=2.47\times 10^{-4}\ C$

Explanation:

The charge on one object, $q_1=9.9\times 10^{-5}\ C$

The distance between the charges, r = 0.22 m

The force between the charges, F = 4,550 N

Let q₂ is the charge on the other sphere. The electrostatic force between two charges is given by the formula as follows :

$F=\dfrac{kq_1q_2}{r^2}\\\\q_2=\dfrac{Fr^2}{kq_1}\\\\q_2=\dfrac{4550\times (0.22) ^2}{9\times 10^9\times 9.9\times 10^{-5}}\\\\q_2=2.47\times 10^{-4}\ C$

So, the charge on the other sphere is $2.47\times 10^{-4}\ C$ .
