The diagram shows a homemade car being pushed with a force of 25 N. The force causes the car to move at a constant speed of 3 m/s2. What will happen if the force is changed to 35 N?

The acceleration of the car will increase drastically

Explanation:

Based on newtons second law of motion, the force applied on a body is directly proportional to the product of its mass and acceleration;

     Force  = mass x acceleration

Since the mass of the car is constant, an increase in force will cause an increase in acceleration.

A decrease in the force will impact a lesser acceleration on the motor car.

This way, the change in velocity of the body per unit of time will increase drastically.

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.
