Increasing the tension of a spring affects a wave on the spring because it increases the frequency. When the tension rises, so does the frequency.
The frequency of a sound wave or any wave for that matter is the reciprocal of the period. That is,
f = 1/T
Substituting the known value of period,
f = 1/(0.05 s)
f = 20 Hz
Thus, the frequency of the wave is equal to 20 Hz.
Answer:
4. total energy
Explanation:
According to Bernoulli's principle at any two points along a streamline flow The total energy that is sum of pressure energy , Kinetic energy and potential energy of the liquid all taken in per unit volume remains constant. Therefore,
for ideal fluid flows through a pipe of variable cross section without any friction. The fluid completely fills the pipe. At any given point in the pipe, the fluid has a constant Total Energy.
Answer:
v = 2 m/s
Explanation:
First, we find the angular velocity of the girl by using the following formula:
Now, for the average velocity of the girl we can use the following formula:
where,
r = radius = 200 m
therefore,
<u>v = 2 m/s</u>
