Asmoke particle has a mass of 1.38*10^-17 kg and it is randomly moving about in thermal equilibirum with room temperature air at 27

The rms speed of the particle is 0.03 m/s.

Explanation:

Given that,

Mass of smoke particle

Temperature =27°C

Suppose we need to find the rms speed of the particle

We need to calculate the rms speed of the particle

Using formula of rms speed

Where, K = Boltzmann constant

T = temperature

m = mass

Put the value into the formula

Hence, The rms speed of the particle is 0.03 m/s.

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
