Robert lifts a 150-newton bucket of water 0.5 meters in 3 seconds. what is the amount of work done on the
bucket?
a. 25 joules
b. 25 watts
c. 75 joules
d. 75 watts

c. 75 joules

Explanation:

Work done(joules)=Force(newton)×Distance(meters)

Given: force=150-newton, Distance=0.5 meters

∴Work done=150×0.5=75 joules.

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.
