When a pendulum is not in the center of gravity in equailrbliaum there is mechanical energy, potential energy is if a rock is cut from the string it will fall
Which ones are you struggling with
Answer:
Explanation:
<u>Functions</u>
When one magnitude depends on other (or others), we usually try to express them as a function which can contain any number of variables, constants, and operations.
The area of a circle is computed by the well-known formula
We are required to use function notation to express the area of a circle f(r) in terms of the radius r. If the radius is in cm, then the area is in .
The required function is
For a radius of 4.3 cm:
After rubbing the head, ballon get all the electrones and negatively charged and hair get positively charged, then their is electro static force between hair and ballon
It increases efficiency. Hope this helps!!!
