On a day when the temperature is 8 degrees celcius, what is the speed of sound in air, in units of m/s.

v = 335.7 m/s

Explanation:

As we know that speed of sound in air is given by the formula

now we have

For air

M = 29 g/mol = 0.029 kg/mol

T = 8 degree Celcius = 273 + 8 = 281 K

R = 8.31 J/mol K

now from above formula we have

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.
