Explanation:
u=0, g=9.8m/s², h=1.2m, v= ?.
from the formula => v²-u²=2gh
=> v²=2×9.8×1.2
=> v = √23.52
=> v = 4.84 m/s .
therefore, with 4.84 m/s the ball will hit the ground.
hope this helps you.
<span>First, you can gather the number of valence electrons. Then find the number of electrons. Do that to make the atoms. Molecules make up atoms. After you need to find how many bonds are in the molecule, which molecules are made up of atoms. Then lastly you find the central atom. </span>
The potential difference must be the same
There are only two things you can do to increase the work output of a machine:
1). Increase the work INput to the machine.
2). Make the machine more efficient ... do things like lubricating it better to eliminate some internal friction.
Answer:
the law of motion
Explanation:
because the wheels are moving it means motion i am not sure which number law it is but I believe that it is 2nd but u should look it up to be safe
