Answer:
Dynamo
Explanation:
Dynamo started to rotate which is known as kinetic energy.When dynamo is in running it produces electricity.dynamo specially used for generating electricity.
Answer:
To find the circumference (orbit) of an object, you use Pi x Diameter.
As you have the circumference of B, you divide it by Pi to get the Diameter.
So 120 divided by 3.141592654 = 38.2 minutes for the Diameter.
As' radius and Diameter will be 3x greater than B.
38.2 x 3 = 114.6
To get back to the orbital period, times 114.6 by Pi, and you will get 360 minutes

Here if we assume that there is no air friction on both balls then we can say
![F = mg](https://tex.z-dn.net/?f=F%20%3D%20mg)
now the acceleration is given as
![F = ma = mg](https://tex.z-dn.net/?f=F%20%3D%20ma%20%3D%20mg)
![a = g](https://tex.z-dn.net/?f=a%20%3D%20g)
so here both the balls will have same acceleration irrespective of size and mass
so we can say that to find out the time of fall of ball we can use
![y = \frac{1}{2}gt^2](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B1%7D%7B2%7Dgt%5E2)
![t = \sqrt{\frac{2y}{g}}](https://tex.z-dn.net/?f=t%20%3D%20%5Csqrt%7B%5Cfrac%7B2y%7D%7Bg%7D%7D)
now from above equation we can say that time taken to hit the ground will be same for both balls and it is irrespective of its mass and size
Answer:
Leaves are the primary source of photosynthesis. Leaves are also have a vital function in plant processes like transpiration and guttation. I hope it helps:)
