Answer: a. net force is acting on object A in the same direction of its motion.
Explanation:
The second law of Newton states that the acceleration of a particular object is dependent on two main things which are the mass and force. According to the law, the acceleration of the object will be directly related to the net force while the acceleration is also relates inversely to the mass.
Therefore, based on the information given in the question, a force is acting on object A in the same direction of its motion.
Answer:
You should have noticed that the number of atoms in the reactants is the same as the number of atoms in the product. The number of atoms is conserved during the reaction. However, you will also see that the number of molecules in the reactants and products are not the same.

Microwave normally penetrate food to the depth of 1 to 1.5 only. In thicker foods, microwave doesn't usually reach the center of the food, the un-reached part normally cook by conduction.
