Kinetic energy is the energy that is associated with motion. It is the energy possessed by an object that is moving. It is calculated from one-half the product of the mass and the square of the velocity of the object. From this, we can calculate the mass of the object. We do as follows:
KE = mv^2/2
500 J = m(5 m/s)^2 / 2
m = 40 kg
The apple is not accelerating. That's a big tip off that the net force acting on it is zero.
1-fixation ( Bacteria Converts nitrogen to ammonium so plants can use it )
2-nitrification ( bacteria changes ammonium to nitrates and plants )
3 - Assimilation (plants absorb nitrates it is then used for Chlorophyll..)
True I hope this helps you out
