Basically anything that isn’t moving has potential energy
<span>KE = (1/2)mv^2
KE = (1/2)(600 kg)(12 m/s)^2
KE = (1/2)(600 kg)(144 m^2/s^2)
KE = 43,200 kg*m^2/s^2 = 43,200 Joules
The kinetic energy of the car is 43,200 Joules.</span>
It's B, I got it right. You would do chest thrusts if their torso is to big to reach around or if they're pregnant.
Answer:
Rock particles can become pollutants by/from the wind. That is called erosion.
They can also become pollutants from man-made tools. For example a tool the polishes rocks releases all the dust and powder substance from the rock into the atmosphere.
There are also minute volcanic which are rock fragments formed during explosive shattering of sticky magma.
