Answer:
t = 0.196 s
Explanation:
The speed of a pulse is determined by the characteristics of the medium, its density and its resistance to stress, as long as these remain the speed will be constant for which we can use the kinetic expressions of the uniform movement
v = x / t
t = x / v
calculate
t = 2/102
t = 0.196 s
The unit of measurement is best to estimate the volume of a juice box will be kilogram.
<h3>What is volume?</h3>
The capacity of a container like how much quantity of liquid can be filled in that container is called the volume.
The juice bottle is estimated by liter as it contains the liquid. The juice box is a solid cardboard with some volume into which juice bottles are kept. So, the weight will be shown in kilograms.
Thus, the unit of measurement is best to estimate the volume of a juice box will be kilogram.

Answer:
option (D) is correct.
Explanation:
According to the work energy theorem, the work done by all forces is equal to the change in kinetic energy of the body.
the kinetic energy of a body is directly proportional to the square of the speed of the body.
As the kinetic energy change, the speed of the body also change.
Option (D) is correct.
pitch is the perceived frequency of a sound wave.
