At room temperature, an oxygen molecule, with a mass of 5.32 x 10^-26 kg, typically has a kinetic energy of about 6.21 x 10^-21 j. how fast is the molecule moving?

v = 483.1 ms⁻¹

Explanation:

Kinetic energy is the energy possessed by a moving object solely due to its motion.

You can get the K.E. of an object using the equation,

K.E. =  (1/2)mv²

So you get, for molecule,  

K.E. = 6.21 X 10^-21 = (1/2)×5.32 X 10^-26×v²

we get, v = 48.31 ms⁻¹

emily ruth's annual premium is $1058.50

step-by-step explanation:

emily ruth is a female of 27 years age purchasing 20 year endowment insurance with face value $25000.

from the given table,

for females, the age of a male 3 years younger should be used.

so, we have to check for 24 year male for 20 year endowment.

it is 42.34 for every $1000 face value.

for a face value of $25000,

it is 25 * 42.34 = $1058.50

∴ emily ruth's annual premium is $1058.50
