Aperson standing on a canoe throws a cement block over the side. the action force on the cement block is 60 n. the reaction force is on the person and canoe. their total mass is 100 kg. what is their acceleration?

Given a person throwing a block standing on a canoe, with a force of 60N and a mass of 100 kg., Acceleration is computed with the formula : 
acceleration = action force / mass
acceleration = 60/100 = .6 m/s squared

Answer : option c) heat is released during the process.explanation :

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.

Standing in the sunlight and feeling the heat on your face (uv radiation is entering the skin, converting to infrared radiation, and is absorbed by your tissues)orstanding near a fire and feeling the heat on your skin (infrared radiation transfer)
