Answer:
I. Period = 1.3 seconds
II. Frequency = 0.769 Hertz
Explanation:
Given the following data;
Number of oscillation = 240 cycles
Time = 5.2 minutes.
Conversion:
1 minute = 60 seconds
5.2 minutes = X seconds
X = 60 * 5.2
X = 312 seconds
To find the following;
I. Period
Mathematically, the number of oscillation of a pendulum is given by the formula;
Making period the subject of formula, we have;
Substituting into the formula, we have;
Period = 1.3 seconds
II. Frequency
Substituting the values into the formula, we have;
Frequency = 0.769 Hertz
Answer:
reflection
Choice D is correct
Explanation:
An echo is simply a reflection of the original sound wave which arrives at the listener with a delay after the original sound. Sound waves can be reflected, that is bouncing off objects in the same manner a solid object can bounce off the ground. The echo sounds entirely the same as the original sound but the direction of the sound is altered.
