Divide the mass by the density of the substance to determine the volume (mass/density = volume). Remember to keep the units of measure consistent. For example, if the density is given in grams per cubic centimeter, then measure the mass in grams and give the volume in cubic centimeters.

Answer: Temperature inversion
Explanation: Temperature inversion is a reverse of the normal temperature flow or distribution of the air,it usually causes temperature to rise as altitude increase towards the troposphere instead of reduction of temperature.
Temperature inversion is caused when warm,dense air flow above cold,less dense air. Temperature inversion is hazardous to man as it traps pollutants close to the Earth surface,this condition limits vertical circulation.
KE= .5*M*V^2
.5*.06*50^2
=75 joules
Answer:
300 J
Explanation:
First of all, we need to calculate the net force acting on the crate, which is given by:
where
F = 100 N is the horizontal push
is the force of friction
Substituting,
Now we can calculate the net work done on the crate:
where
d = 10 m is the displacement
Substituting,
According to the work-energy theorem, the kinetic energy gained by the crate is equal to the work done on it: therefore, the answer is 300 J.
