Answer:
Biomass-Total of mass of organisms in a given area/volume
Biofuel-A fuel directly from living matter.
The variable you can change in an experiment is ( B ) A dependent variable
Explanation:
PE= mgh
6 J= (3m) (9.81 m/s2) (mass)
mass=( 6)/(3×9.81)
mass= 0.20 Kg
Explanation:
W = mg
m = 740g = 740/1000kg = 0.74kg
g = 15.6ms^-2
W = 0.74x15.6
W = 11.544 N
