The frequency of the 10th harmonic is 800 Hz
Explanation:
The frequency of the nth-harmonic for the standing waves in a string is given by the equation
where
is the fundamental frequency of the string
In this problem, we are given the frequency of the 3rd harmonic:
Which can be rewritten in terms of the fundamental frequency
So we find :
Now that we have the fundamental frequency, we can find the frequency of the 10th harmonic, with n = 10 :

Answer:
g = 12.22 m/s²
Explanation:
The time period of this pendulum is given as follows:
but the formula for the time period of a simple pendulum is as follows:
where,
L = length of pednulum = 48 cm = 0.48 m
g = magnitude of th gravitational acceleration on this planet = ?
Therefore,
<u>g = 12.22 m/s²</u>
Answer:
Explanation:
The interrelationship between the distance covered by a body, the initial velocity of the body, and the time taken by the moving body during its motion is given by the second equation of motion.
The second equation of motion is given as follows:
where,
s = the distance covered by the body
vi = initial velocity of the body
t = time taken by the body during motion
a = acceleration of the body
