Answer:
Yes, this is <em><u>true</u></em>. Hope this helps :)
Answer:
Explanation:
Given
mass (m)= 20 kg
acceleration (a)= 10 m/s^2
Force (f)= m a
= 20 * 10
= 200 N
It's kinetic energy as the ball the ball isn't raised above the ground it does not have any gravitational potential energy.
To find the kinetic energy of the ball you will have to use the formula:
KE=0.5 x m x v squared
m being mass and v being velocity
so the calculation is:
0.5 x 2 x 10 x 10= 100J
There are a lot of reasons why gum is bad for you but a main reason because if you make a bubble and swallow it you could choke. Another reason is because it breaks down your gums.
The fetus relies upon its mother as it develops. These are some of the things it needs:

The developing fetus also needs its waste substances removing.
The fetus is protected by the uterus and the amniotic fluid, a liquid contained in a bag called the amnion.
