Answer:
Option C
Sound quality
Explanation:
Sounds with the same pitch and loudness means they share natural frequency where frequency here implies the the number of vibrations that an individual particle makes per unit time (seconds). Additionally, when the pitch and loudness are the sane, the resonance and standing waves of these sounds will be similar. However, the quality of the sounds will vary. Therefore, option C is the correct one.
Answer:
1 work is scalar quantity
2 it si unit of work is joule
3The equation of caculate is work= Force× Displacement
1 power is scalar quantity
2 it si unit of power is watt
3 the equation of calculateis power= work \time
Answer:
In physics, motion is the change in the position of an object over time. Motion is mathematically described in terms of displacement, distance, velocity, acceleration, speed, and time. The motion of a body is observed by attaching a frame of reference to an observer and measuring the change in position of the body relative to that frame.

Answer:
Explanation:
Car is 25 m long . worker moves at speed 3.0 m/s with respect to the car
Time taken to reach the other end
= 25 / 3 = 8.333 s
Displacement of flatcar during this period
= 7 x 8.333
= 58.33 m
