Using V²=u² +2gH
let's assume the ball falls from rest, then it's initial velocity = 0ms-¹ (U=0)
then from the above info V= 35ms-¹
g= 10ms-² (value of acceleration due to gravity to the nearest tens)
so input your values above into the given formula to find height
35² = 0² +2×10×H
1225 = 20H
H = 1225÷20 = 61.25m
The 'Rite of Spring' was composed by Igor Stravinsky.
-- Radio waves. (To hear the weather while I'm waking up.)
-- Light waves. (To see where the dog is so I don't step on him.)
-- Infrared waves. (To make my toast for breakfast.)
-- Microwaves. (To heat my oatmeal for breakfast. Also when I go in to my job as a microwave communications engineer.)
Answer:

Explanation:
The electron is the particle that rotates around the nucleus of the atom; it has a negative electric charge equal to :

which is known as fundamental charge.
For an object containing N excess electrons, the total charge of the object is

In this problem, the number of excess electrons in the object is:

Therefore, by plugging it the numbers, we can find the value of Q, the total charge of the object:

Newton is a unit of force. Joules is an amount of work which is equal to the force times distance, or newton meters. So the product of newtons and meters makes joules.
