Since wavelength x frequency = speed, wavelength is proportional to speed.
So, Middle C has a longer wavelength in water than in air.

Answer:
The time constant is 76.92 sec.
Explanation:
Given that,
Mass of bob = 1.00 kg
String length=1.00 m
Time = 25.0 s
Suppose we need to calculate the numerical value of the time constant τ.
We need to calculate the numerical value of the time constant τ
Using formula of time constant
Put the value into the formula
Hence, The time constant is 76.92 sec.

Smokey ! Mass doesn't change ! You're supposed to know that. If the ball has 5 kg of mass on Earth, then it has 5 kg of mass on the moon, on Pluto, in orbit, in free fall, on a roller coaster, in the grocery store, in church, in the shower, or in my sock drawer. Mass doesn't change ! WEIGHT depends on gravity, so it can change. MASS doesn't and can't.
