Answer:
the <u>Fundamental Frequency</u> of vibration of a wave is defined as that which has the lowest frequency
Explanation:
As we know that the frequency of vibrations on a string is given as
now we know that
N = number of harmonics
v = speed of the wave
L = length of the string
So here for the lowest frequency of the wave we know that
N = 1
so lowest frequency of the wave is known as fundamental frequency of the wave
the <u>Fundamental Frequency</u> of vibration of a wave is defined as that which has the lowest frequency

122.5 N/m
Explanation:
According to the law of conservation of energy, if there is no air resistance or frictional forces, the initial elastic potential energy of the spring toy is entirely converted into gravitational potential energy when the toy reaches the highest point.
Therefore, we can write:
where the term on the left is the initial elastic potential energy while the term on the right is the gravitational potential energy, and where
k is the spring constant
x = 0.02 m is the compression of the spring
m = 0.01 kg is the mass of the toy
h = 0.25 m is the height reached by the toy
is the acceleration due to gravity
Solving for k,
Answer:
Velocity = 3.25[m/s]
Explanation:
This problem can be solved if we use the Bernoulli equation: In the attached image we can see the conditions of the water inside the container.
In point 1, (surface of the water) we have the atmospheric pressure and at point 2 the water is coming out also at atmospheric pressure, therefore this members in the Bernoulli equation could be cancelled.
The velocity in the point 1 is zero because we have this conditional statement "The water surface drops very slowly and its speed is approximately zero"
h2 is located at point 2 and it will be zero.
