A methane bubble starts at the bottom of a lake (15.0 meters down) where the water temperature is 4.00C and rises to the surface
where the water temperature is 22.0C (hey, it’s summer at Rock Lake, and this is a reasonable temperature.) and the air pressure is 0.920 atmospheres. Assuming the gas is ideal and rises slowly enough that its temperature changes exactly as the water does, find the factor by which the final volume is different than the initial.

Solution :
c). force applied by Abe
force applied by Barry
force applied by Eric
Resultant force
in the vector form can be written as :
in the vector form can be written as :
The resultant,
= 84.853 N
d). As the three forces are in equilibrium, therefore,
e). The direction of the force exerted by Eric is exactly opposite to the direction of the resultant force.
The direction of the resultant force is :
= 45° north east
The direction of the force E is 45° west or 45° south west.
