Cherries on a tree freeze at -2°. the weather forecast said that tonight's low is -5° c. the old farmer sprays down his trees with water. he days that it will protect them. truth, or old wives tale? why?

plasma - state of matter made up of electrically charged particles

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
