0.5I0
Explanation:
Because once ligh passes though any polarizer 50% of it is gone. The second polarizer is also oriented in the same direction so it passes through with no effect.
Answer: In an exothermic reaction, the products have less energy than the reactants.
Explanation: There are two types of reactions:
1. Endothermic reactions: These are the reactions in which energy is required in the reaction. The energy of the products are more than the energy of the reactants.
2. Exothermic reactions: These are the reactions in which energy is released in the reaction. The energy of the products is less than the energy of the reactants.
Hence, in an exothermic reaction, the products have less energy than the reactants.

I had the same question :)
Answer:
Explanation:
The law of inertia states that if an object is in motion will remain in motion unless an external force is applied to it.
law of inertia for the rotating system in terms of angular momentum states that the angular momentum of a system will remain the same unless an external torque is applied to the system.
External Torque either increases or decreases the angular velocity thus changing angular momentum.
