Q1. How many 104 W lightbulbs can you use in a 134 V circuit without tripping a 14 A circuit breaker? (The bulbs are connected in parallel that means that the potential difference across each lightbulb is 133 V.)

Q2. A 1650-kg car is travelling at 31.2 m/s. How fast must a 91.0-kg bicycle and rider be travelling to have the similar kinetic energy as the car?
