The answer is 2,125,440 m/s
Exothermic is the answer to your question
Tennis ball and bowling ball would hit the ground at the same time
Answer:
30m/s
Explanation:
Suppose there's no friction between the office chair and the floor. The only thing that impact the motion of the boy is the ejected carbon dioxide. We can apply the law of momentum conservation to find the his (the boy, the chair and the empty extinguisher) after the extinguisher is emptied.
Before the ejects, the system momentum is 0, due to at rest and no speed
After the ejects, momentum of the carbon dioxide is
9*20 = 180 kg m/s
The momentum of his is then
P + 180 = 0
P = -180
MV = -180
(26 + 16 + 18)V = - 180
V = -180/(26 + 16 + 18) = -30 m/s
So he would have a speed of 30m/s in the opposite of the ejected carbon dioxide direction
Answer:
A variable is any characteristics, number, or quantity that can be measured or counted. A variable may also be called a data item. Age, sex, business income and expenses, country of birth, capital expenditure, class grades, eye colour and vehicle type are examples of variables.
