On the "Mendel's Work worksheet that we did together in class. What was the answer to #1 What trait in pea plants is being studied in the cross above?"

petroleum? coal maybe?

answer seismograph;

5.6⋅10−^19  j

do you need the explaination?

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.
