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 =
Where
T = Tension in the cord = 150N
μ = Mass per unit length = mass/Length = 0.65/28 = 0.0232 kg/m
So
v =
= 80.41 m/s
Now the time-taken by the wave = t = Length/speed = 28/80.41=
0.348s
False.
As temperature increases the more the electrons begin to vibrate more, as it decreases they vibrate less.
Getting a good night sleep can benefit you in a lot of ways. Also that’s not a question.
Exert force upward.
Like when you pick something up from the floor, or walk up the stairs.
