Answer:
Speed and direction affect pitch.
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:
the action or process of moving or being moved
Explanation:
Answer:
B
Explanation:
Heat energy of a substace can be calculated using
Q = mcθ
where Q = Heat energy
m =mass
c = specific heat capacity
θ =temperature difference
Temperature difference is final temperature - initial temperature.
So we get,
Q = 1 × 600×(100-20)
= 48000 J
