The required period of the wave is 0.125 seconds.
In physics, frequency and period are two related concepts that are used to describe the properties of waves. Period, on the other hand, is a measure of the time it takes for one complete cycle of a wave.
Frequency is a measure of how many cycles of a wave occur in one second. It is measured in units of Hertz (Hz), which is defined as cycles per second.
Here,
The period (T) of a wave is the time it takes for one complete cycle of the wave. It is related to the frequency (f) of the wave by the formula:
T = 1/f
Where T is in seconds and f is in Hertz (Hz).
Given that the frequency of the wave is 8 Hz, we can calculate the period as follows,
T = 1/f
T = 1/8
T = 0.125 seconds
Therefore, the period of the wave is 0.125 seconds.

B. More mass is added to a wheelbarrow, and a larger force is
required to move it.
C. A person pushes a wheelbarrow, causing it to move forward.
D. The force of a wheelbarrow on the ground is equal to the force of
the ground on the wheelbarrow.
More mass is added to a wheelbarrow, and a larger force is required to move it - illustrates Newton's second law.
An object's push or pull is seen as exerting a force. The interaction of the objects produces push and pull. You can also use words like stretch and squeeze to describe force.
The definition of force in physics is: The push or pull on a mass-containing item changes its velocity.
Newton’s second law of motion states that “Force is equal to the rate of change of momentum. For a constant mass, force equals mass times acceleration."
Hence more mass is added to a wheelbarrow, and a larger force is required to accelerate, i.e., move it.

Answer:B
Explanation:
Mass
a)
KE=1/2mv^2
F= -kx
KE= -kx
-kx= 1/2mv^2
when u quadruple the m, the x also quadruples. when the speed is multiplied by 3, since it is v^2, the x is multiplied by 3^2 , which is 9
so distance the spring compressed is x×4×9= 36x
b) using the KE formular too,
when the v is tripled, since formula is v^2, the resulting KE will be multiplied by 3^2, so KE now= 9K
Answer:
The currency for performing work is called : Energy
And Energy's unit of measurement is : Joule
The amount of energy you've inputed will always equal the output.
For example, in order to do a 500 joules of work, you need 500 joules of energy
