The frequency of the oscillation in hertz is calculated to be 0.00031 Hz.
The frequency of a wave is defined as the number of cycles completed per second while the period refers to the time taken to complete a cycle. The frequency is the inverse of period.
So;
Period(T) = 54 minutes or 3240 seconds
Frequency (f) = T-1 = 1/T = 1/3240 seconds = 0.00031 Hz

The mechanical advantage of the lever is 3 and the right option is A.) 3.
<h3>What is mechanical advantage?</h3>
Mechanical advantage can be defined as the ratio of load to effort in a machine.
To calculate the mechanical advantage of the lever, we use the formula below.
Formula
- M.A = y/x................ Equation 1
Where:
- M.A = mechanical advantage of the lever
- y = distance moved by effort (input arm)
- x = distance moved by load (output arm)
From the question,
Given:
Substitute these values into equation 1
Hence, The mechanical advantage of the lever is 3 and the right option is A.) 3.

Answer:
increases
Explanation:
because as when the electimagnatics coul coul starts to increase the magnetic field also increases
Average Velocity=Total Distance/Total Time
If one body is positive, and the other is negative, they tend to attract!
