An object accelerates 1.3 m/s2 when a force of 3.7 newtons is applied to it. What is the mass of the object?

Explanation:

The mass of the object can be found by using the formula

f is the force

a is the acceleration

From the question we have

We have the final answer as

Hope this helps you

0.67 Hz

Explanation:

Given that:

Number of oscillations = 120

Time taken for oscillations = 3 minutes

Since standard unit of time is seconds, convert 3 minutes to seconds

(If 1 minute = 60 seconds

3 minutes = 3 x 60 = 180 seconds)

Then, recall that frequency is the number of complete cycles or oscillations in one second, and its unit is Hertz.

Thus, frequency = (number of oscillations / time)

F = 120 / 180 seconds

F = 0.67 Hz

Thus, the frequency of a simple pendulum is 0.67Hz
