Answer:
Explanation:
The force of friction equals the sine component of the force due to gravity
Answer:
Yes the valency of oxygen is 2
Answer:
1. Either larger or smaller than the displacement of either wave acting alone, depending on the signs of the displacements of the two waves.
The formula for both is v(t) = v0 + a*t
b) v(8) = 0 + 6m/s^2 *8s = 48 m/s
now we know the beginning (2) and end speed (14), but not the time:
c) 14 = 2 + 1.5*t => t = (14-2)/1.5 = 8 seconds
Answer:
<u><em>Electric Potential Energy:</em></u>
The energy that is needed to move a charge against an electric firld is called Electric Potential Energy
<u><em>Electric Potential Difference:</em></u>
The amount of work done in carrying a unit charge from one point to an other in an electric field is called Electric Potential Difference.
<u><em>Relation:</em></u>
Relation between Electric potential and electrical potential energy is given by

Here PE represents Electric potential energy
and
is Electric potential difference
it means electric potential difference is the difference in electric potential energy divided by the charge.
