Answer:
9.0 m/s
Explanation:
The problem can be solved by using the following suvat equation:
where
v is the final velocity
u is the initial velocity
is the acceleration of gravity
t is the time
When the ball reaches the maximum height, the velocity becomes zero. If we consider this as initial point of the motion, we can write
u = 0
The time it takes for the ball to go down from the maximum heigth to the ground is half the total time, so
And solving the formula for v, we find the final velocity:
So, the final speed is 9.0 m/s.
The advantage is having new cells to clone or help different organisms with.
Hope this helps:)

Hmmmm, you either tell your parent, try to fix it, or blame it on the dog with a baseball bat that always comes on your yard and tries to eat you.

Answer:
the conversion of matter into energy
Explanation:
A nuclear reaction is a reaction in which there is a change in the nuclei of the atoms involved. The two most important examples of nuclear reactions are:
- Nuclear fission: it occurs when a heavy, unstable nucleus breaks apart into two or more lighter nuclei
- Nuclear fusion: it occurs when two lighter nuclei fuse together into a heavier nucleus
In both cases, the total mass of the final products is smaller than the total mass of the initial nuclei: this means that part of the mass of the initial nuclei has been converted into energy, according to Einstein's formula:
where 
is the variation of mass and c is the speed of light. Since the value of c is very large, we can see from the formula that even a small amount of is able to produce a huge amount of energy, and this is a typical feature of any nuclear reaction.
