Acceleration formulae is:
a=Fnet/mass
According to the question
a=7500N/1500kg
a=5m/s sq.
Weight equals mass multiplied by the acceleration due to gravity.
What’s the question, but your a k pop stan hi
Its D because of the emission spectra
As we know that speed of sound is

frequency of sound is

now we know that frequency of sound and speed of sound is related to each other by the following formula




<em>so wavelength of sound is 25 cm or 0.25 m</em>
