Answer: 24.2

Explanation:

Given that:

Time taken for sound travel = 0.02 seconds

Speed of traveling sound wave = 1210 m/s

Depth of pond = ?

Recall that speed is obtained by dividing the distance covered (depth travelled) by the time taken.

Hence, speed = (depth travelled / time taken)

1210 m/s = depth travelled / 0.02 seconds

Depth travelled = 1210 m/s x 0.02 seconds

Depth travelled = 24.2 m

Thus, the pond is 24.2 metres deep

Figure 13 shows a child’s toy . The toy hangs from a hook in the ceiling.
Grace [21]

The number of oscillations of the toy in a second is 1.25.

<h3>What is frequency?</h3>
  • This is the number of complete oscillation of an object is a given period.

The given parameter:

  • Frequency of the toy, F = 1.25 Hz

The frequency of an object is calculated as follows;

f = \frac{n}{t} \\\\

where;

  • n is the number of oscillations
  • t is the time of motion

The number of oscillations of the toy in a second is calculated as follows;

1.25 = \frac{n}{1} \\\\n = 1.25
