Answer:
Isaac Newton
Explanation:
Newton's laws of motion, three statements describing the relations between the forces acting on a body and the motion of the body.
Because the core is a big ball of iron
Answer:
The power expended by the car during the acceleration is 116.38KW
Explanation:
Power is a term that defines the rate at which energy is expended whenever work is done.
Power can be given as Force X velocity.
Force can be found using the formula:
F = mass X acceleration.
In this case,
F = 1100kg X 4.6m/s2
F = 5060 N
The final velocity, v of the car can be obtained from this formula:
v = u+ at
U = initial velocity = 0 (since the car started from rest)
a = acceleration = 4.6m/s2
t = time = 5 seconds
v = 0 + 4.6 X 5 = 23 m/s
Therefore, the power expended is 5060N X 23m/s=116,380W
The power expended by the car during the acceleration is 116.38KW
Answer: matter is anything that has mass and volume
Explanation:
Answer:
The number of people at game are approximately 22909
Explanation:
Given data
When one person shout 
When n number of person shout together 
The sound intensity level during one person shout is given by:
The sound intensity level during n number of person shout is given by:
Since each person generates same sound intensity and hence total number of persons can be determined as
Hence
The number of people at game are approximately 22909
