Iapply 40,000 joules of energy to a 400 gram block of a substance, which causes its temperature to rise 40 degrees. this substance has a specific heat of j/kg°c. (a) 2500 (b) 2.5 (c) 5.0 (d) cannot be determined

Answer: buoyancy forceexplanation: 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.

B) raising the temperature and reducing the volume of the gas.|-/
