The answer is A. voice uses a wider range of pitch and volume as compared to speaking
Answer:
The amount of energy carried by a wave is related to the amplitude of the wave
Explanation:
A high energy wave is characterized by a high amplitude; a low energy wave is characterized by a low amplitude. The energy imparted to a pulse will only affect the amplitude of that pulse.
Hope this helped!!!
Answer:
Explanation:
Generally the workdone in moving the proton is mathematically represented as
Where 
So
Here 
is the velocity at A with value 50 m/s
So
Also
Here is the velocity at A with value 
=> 
=> 
So
Now this workdone is also mathematically represented as
So
Here 
So
Generally proton movement is in the direction of the electric field it means that 
So
Answer:
Displacement is 50 m
Explanation:
Distance is simply the measurement of the sum of all paths travelled.
Thus, since he swims the 50m length pool 3 times, then the total distance = 50 × 3 = 150 m
Whereas, displacement is the measurement of length of the shortest path from initial point to final point.
In this case initial point to final point is 50m. Thus, the displacement is 50 m
