Work done can be calculated from force and distance the object moves.
The equation relating work done, force and distance is,
Given the force acting on the object = 289 N
Distance the object moves = 29 m
Calculating the work done from force and distance:
Work = Force * Distance
= 289 N * 29 m
= 8381 J

True.
Nuclear Fusion is a reaction process that involves combination of smaller nuclei to form larger one.
There are 4 oxygens in the compound
Answer:
0.1077 grams
Explanation:
First we will employ the ideal gas law to determine the number of moles of nitrogen gas.
PV=nRT
P=2 atm
V=20L
R=0.08206*L*atm*mol^-1*K^-1
T=323.15 K
Thus, 2atm*20L=n*0.08206*L*atm*mol^-1*K^-1*323.15K
K, atm, and L cancels out. Thus n=2*20mol/0.08206*323.15=1.5 moles
Lastly, we must convert the number of moles to grams. This can be done by dividing the number of moles by the molar mass of nitrogen gas, which is 14 grams.
1.5/14=0.1077 grams
