A 0.20 kg mass on a horizontal spring is pulled back 2.0 cm and released. If, instead, a 0.40 kg mass were used in this same exp

Answer:
The total mechanical energy remains unchanged regardless of adjustments in mass. It stays consistent
Explanation:
In a spring-mass system, the collective mechanical energy equates to the elastic potential energy whenever the system is at amplitude. This can be defined as:
(1)
k: spring constant
A: amplitude of motion = 2.0cm
As reflected in equation (1), the total mechanical energy is independent of the object's mass; it solely relies on the amplitude A and the spring constant.
Therefore, whether you use a mass of 0.40kg or 0.20kg, the total mechanical energy remains constant.

Answer:
Explanation:
Within a duration of 60 seconds, six waves are observed.
With a total of 6 waves,
this equates to 3 wavelengths.
As a result,
the period for each wavelength is calculated as 60 divided by 3.
Thus, period = 20 seconds.
According to the frequency-period relationship,
f = 1 / T
f = 1 / 20
f = 0.05 Hz
Conclusion:
The total net force acting on the objects is 16 N, directed towards the right.
Clarification:
It is stated that,
The force exerted by the dog, (to the right)
The force exerted by Simone, (backward)
Here, assume the backward direction is negative and the right direction is positive.
The net force will move in the direction where the larger force is present. The net force can be calculated as:
F = 16 N
Thus, the net force amounts to 16 N, acting towards the right.
