Protons are the subatomic particle that lies in the nucleus of an atom
B because science is to experiment and that’s y it’s b hope you have a nice day or night
Ans: Time <span>taken by a pulse to travel from one support to the other
= 0.348s</span>
Explanation:First you need to find out the speed of the wave.
Since
Speed = v =
![\sqrt{ \frac{T}{\mu} }](https://tex.z-dn.net/?f=%20%5Csqrt%7B%20%5Cfrac%7BT%7D%7B%5Cmu%7D%20%7D%20)
Where
T = Tension in the cord = 150N
μ = Mass per unit length = mass/Length = 0.65/28 = 0.0232 kg/m
So
v =
![\sqrt{ \frac{150}{0.0232} }](https://tex.z-dn.net/?f=%20%5Csqrt%7B%20%5Cfrac%7B150%7D%7B0.0232%7D%20%7D)
= 80.41 m/s
Now the time-taken by the wave = t = Length/speed = 28/80.41=
0.348s
