Answer:
Two tunnig fork of frequency 520 Hz and 524Hz are vibrated together. It means beats form due to it .
f₁ = 524 Hz
f₂ = 520 Hz
Beat period = 1/number of Bea are formed per unit time
= 1/(f₁ - f₂)
= 1/(524 - 520)
= 1/4 sec
Now, time inveral between successive maximum and minimum intensities = beat period= 1/4 sec

Explanation:
The formula for work is force times distance.
B. centrifugal
C. gravitational
D. frictional
b. luminosity.
c. distance from Earth.
d. absolute magnitude. E. surface temperature.
Answer:
Luminosity
Explanation:
The apparent magnitude is a measure of the star's apparent luminosity, the apparent luminosity is directly related to the star's apparent magnitude.
The star's luminosity is the measure of the star's brightness and this diminishes with distance, the luminosity of a star also depends on the size of the star, this means that a star's magnitude and luminosity are directly related.
