It is a scaler because it’s only fully describes by a magnitude and a numerical alone
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 wave in the string travels with a speed of 528.1 m/s
Explanation:
Wave speed of sound waves in a string, v, is related to the Tension in the string, T, and the mass per unit length, μ, by the relation,
v = √(T/μ)
μ = 5.20 × 10⁻³ kg/m
T = 1450N
v = √(1450/0.0052) = 528.1 m/s
Hope this Helps!!!
