Work= force x distance
work= 750 x 2
work =1500
power =work/time
power= 1500/ 0.3
power= 5000W
answer: b. 5000W
Answer: Third option
F = 250w
Explanation:
The impulse can be written as the product of force for the time interval in which it is applied.

You can also write impulse I as the change of the linear momentum of the ball

So:

We want to find the force applied to the ball. We know that
milliseconds = 0.03 seconds
The initial velocity
is zero.
The final speed 
So


We must express the result of the force in terms of the weight of the ball.
We divide the expression between the acceleration of gravity


The answer is the third option
Answer: C- the outer core
Explanation: The outer core is a thick layer of molten rock that encircles the inner core.
The contract of citizenship, the contract of merriage, the contract of loan, the contract of power, and the contract of health care. All these are examples of a contract on institutional level
Answer:
A = [kg]
B = [m/s²]
Explanation:
E = ½ Av² + Bmx
Substitute the units:
[J] = ½ A [m/s]² + B [kg] [m]
A Joule written in base units is:
1 J = 1 Nm = 1 kg m²/s²
Each term must have the same units.
[kg m²/s²] = A [m/s]²
[kg m²/s²] = A [m²/s²]
A = [kg]
[kg m²/s²] = B [kg] [m]
B = [m/s²]
