Answer:
The period of oscillation is 1.33 sec.
Explanation:
Given that,
Mass = 275.0 g
Suppose value of spring constant is 6.2 N/m.
We need to calculate the angular frequency
Using formula of angular frequency
Where, m = mass
k = spring constant
Put the value into the formula
We need to calculate the period of oscillation,
Using formula of time period
Put the value into the formula
Hence, The period of oscillation is 1.33 sec.
The one that will change the velocity of a periodic wave is :
B. Changing the medium of the wave
Waves is always determined by the properties of the medium, which means that changing the medium will change the velocity of the wave
