Answer:
0.186 N-m
Explanation:
mass of the grindstone, 
radius, 
Frequency, 
time, 
final angular velocity, 
Initial angular velocity,
Angular acceleration of the grind stone is:
Moment of inertia:
Torque exerted by the ax on the grind stone is:
Average velocity is calculated as the division of displacement and change in time so the answer would be 804 km/36000 s=0.02 m/s
The researcher can change one isotope into a different isotope of the same element by ADDING OR REMOVING NEUTRONS.
Isotopes refers to two or more forms of the same element, which have the same number of protons but different number of neutrons. The difference in the number of neutrons of a particular element is what brings about isotopes, thus, isotopes can be created by removing or adding neutrons to a particular element.<span />
A) Water freezing
This is called the process of turning water as a liquid to its solid form which is ice.
Ice is almost together as one unlike liquid. This is why the molecules are more orderly.
The process of freezing is exothermic which means the heat has to be removed in the process.
Craters flat land or rock
