Q. How many 109 W lightbulbs can you use in a 134 V circuit without tripping a 12 A circuit breaker? (The bulbs are connected in parallel, which means that the potential difference across each lightbulb is 134 V.)

Q. An artillery shell is fired with an initial velocity of 300 m/s at 45.0° above the horizontal. To clear an avalanche, it explodes on a mountainside 39.0 s after firing. What are the x and y components of the shell where it explodes, relative to its firing point?

x = 1 m
y = 2 m
