Answer:
Explanation:
<u>Given Data:</u>
Weight = W = 65 N
Height = h = 2 m
Time = t = 4 secs
<u>Required:</u>
Power = P = ?
Work Done in the form of Potential Energy = P.E. = ?
<u>Formula:</u>
P.E. = Wh
P = P.E. / t
<u>Solution:</u>
P.E. = (65)(2)
P.E = 130 Joules
P = P.E. / t
P = 130 / 4
P = 32.5 Watts
Hope this helped!

Flase plant cells and animals cells have almost the same major parts but some parts are different or in different places
A scientific theory is something that can not be proven through experimentation, hope this helps
In March and September both of the hemispheres receive the same amount of energy from the sun. this is because neither end of the axis is tilted toward the sun.
Answer:
2.30 × 10⁻⁸ N if the two electrons are in a vacuum.
Explanation:
The Coulomb's Law gives the size of the electrostatic force between two charged objects:
,
where
- is coulomb's constant. in vacuum.
- and are the signed charge of the objects.
- is the distance between the two objects.
For the two electrons:
- .
- .
- .
The sign of is negative. In other words, the two electrons repel each other since the signs of their charges are the same.
