Answer:
Option C. Rate of change of velocity
Explanation:
To know the correct answer to the question, it is important we know the definition of power.
Power can be defined as the rate at which work is done. Mathematically, it is expressed as:
Power = work / time
Work and energy has the same unit of measurement i.e joule. Thus, power can also be defined as the rate at which energy is transferred i.e
Power = enery / time
Energy is measured in Joules and time in second. Thus, power can also be defined as amount of joules transfered per second.
Power = Joule / sec
The rate of change of velocity on the other hand is termed acceleration.
Thus, the answer to the question is option C.
Answer:
e. all of the above
Explanation:
In simple harmonic motion, the acceleration is given as;
a = -ω²x = -(2πf)²x
where;
ω is the angular velocity
f is the frequency
x is the displacement
A is the amplitude
Thus, In simple harmonic motion, the acceleration is proportional to the amplitude, velocity, frequency, and displacement.
The correct option is E.
"all of the above"
It is the third option, buoyant force.
