Displacement is which of the following types of quantities?A. vectorB. scalarC. magnitudeD. dimensional

agasfer [191]

Answer: A. vector

Explanation:

Movement is the change of position of a body at a certain time. The body that experiences this change of position is called mobile.

In this sense, the displacement is the distance in a straight line between the initial and final position of this mobile, which differentiates it from the trajectory, which is the path followed by the body in its movement and a scalar magnitude.

Hence, the displacement is a vector.

Beat frequency problem. Your ear simultaneously hears waves from different sources, so it can hear beats from the two speakers.

podryga [215]

Completed question:Suppose one speaker is driven at 570 Hz and the other at 554 Hz. What is the beat frequency in Hz? The average frequency in Hz?

Answer:

Beat frequency= 16Hz

Average frequency = 562Hz

Explanation:

Beat frequency f = f2-f1

Where f2 is frequency of source with higher frequency

f1 is frequency of source with lower frequency

f1= 554Hz, f2= 570Hz

beat frequency (f) = 570 -554

= 16Hz

Average frequency = $\frac{554+570}{2}$

= $\frac{1124}{2}\\ =562Hz$
