Power is defined as the amount of work over a certain amount of time. Work is also Force times the distance traveled. Simplifying the expression makes it Power=Force x Velocity. Since we are given that the power is 4500 W and the force is 100 N, dividing the Power by force gives 45 m/s, which is the velocity of the ball.
The average power produced by the soccer player is 710 Watts.
Given the data in the question;
- Mass of the soccer player;
- Energy used by the soccer player;
- Time;
Power;
Power is simply the amount of energy converted or transferred per unit time. It is expressed as:
We substitute our given values into the equation
Therefore, the average power produced by the soccer player is 710 Watts.

Answer:
Your answer is: D) 110N
Hope this helped : )
Explanation:
In order for the wood to sink, it's specific gravity must equal 1 (or greater).
Specific gravity = .6 kg/m^3= Mass/volume
F (Newtons or kg x m/s^2) = Mass*9.8m/s^2.
Therefore, Mass = 160 N / 9.8 m/s^2= 16.32 kg
Volume = Mass/Specific Gravity = 16.32kg/.6 kg/m^3 = 27.2 m^3
Desired Specific gravity = 1 = (Mass + additional force/9.8m/s^2)/Volume = (16.32 kg +X / 9.8m/s^2)/27.2m^3
Solving for the additional force: X = 106.66...N
The answer is D, 110 N will be required to sink the block of wood.
Your pancreas is an organ that is apart of the digestive system. It produces insulin and other enzymes that helps break down the food you eat.
It is found across the back of the abdomen, that is behind the stomach.
