Calculate the momentum of a 1000 kg sports car traveling at 30 m/s.

ozzi

Answer:

30,000 kgm/s

Explanation:

m = 1000 kg

v = 30 m/s

Plug those values into the equation:

p = mv

p = (1000 kg)(30 m/s)

p = 30,000 kgm/s

A sound wave travels through a column of hydrogen at STP. Assuming a density of rho = 0.0900 kg/m3 and a bulk modulus of β = 1.4

STALIN [3.7K]

Answer:

speed of sound will be 1256 m/sec

Explanation:

We have given density $\rho =0.09kg/m^3$

And bulk modulus $\beta =1.42\times 10^5Pa$

We know that speed of sound in a medium is given by

$v=\sqrt{\frac{\beta }{\rho }}$ , here $\beta$ is bulk modulus and $\rho$ is density

So speed will be $v=\sqrt{\frac{1.42\times 10^5}{0.09 }}=12.56\times 10^2=1256m/sec$

So speed of sound will be 1256 m/sec
