Find the average translational kinetic energy and the rms speed of the o2 molecules in air at room temperature (20°c). [hint: the atomic mass of oxygen is 16.0 g/mol.]

object 2 because all the other ones are wrong

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.

a=d/t

a="triangle"v/t

explanation:

a = acceleration
