Answer:
0
Explanation:
Since momentum is given by:
Therefore momentum is a vector quantity in the direction of velocity.
- Inelastic collision is the type of collision in which the masses combine after collision and start moving in the direction of the greater momentum but here in this case we have the momentum equal and opposite in direction.
<u>This case can be described mathematically as:</u>
since the mass and velocity are equal:
net momentum:
Answer:
Average power output of athlete = 11025 Watts
Explanation:
Work done is defined as the product of force applied and the displacement perpendicular to the force.
Work = 
Power is defined as work done per unit time.
Power = 
Here the person lifts 900 kg.
Height = 2.5 m
Time interval = 2 seconds
Force = 
= 
= 8820 N
Work done =
= 
= 22050 J
Power = 
= 11025 Watt
Answer:
Gamma rays
Explanation:
Have the highest energies. The shortest wavelengths, and the highest frequencies.
The heat required to raise the temperature of the unit mass of a given substance by a given amount (usually one degree).
or C. Mass if you're on plato
Palm of your hand should be the correct answer if i remember correctly
