The speed of sound in a container of gas at 20.0°c is v. if the temperature of the gas is increased to 80.0°c, the new speed will be?

Answer : The new speed will be, 1.098v

Explanation :

The formula used for speed of sound in a container of gas is:

where,

c = speed of sound

R = gas constant

= adiabatic constant

T = absolute temperature

M = molecular mass of gas

As,

or, we can say that

           .............(1)

Given:

=

=

= v

Now put all the given values in the above formula 1, we get:

Thus, the new speed will be, 1.098v

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
