How many 190W lightbulbs can you use in a 180-V circuit without tripping a 8-A circuit breaker? (The bulbs are connected in parallel, which means that the potential difference across each lightbulb is 180V. Also
calculate the resistance of the 190W lightbulb.
(a) No. of 190-W lightbulbs we can use without tripping a 8-A circuit breaker=
(b) Resistance of 190W lightbulb in ohm =

Heeelp me fast pls​

Awater slide of length l has a vertical drop of h. abby's mass is m. an average friction force of magnitude f opposes her motion. she starts down the slide at initial speed vi. use work-energy ideas to develop an expression for her speed at the bottom of the slide. then evaluate your result using unit analysis and limiting case analysis. express your answer in terms of the variables h, m, l, vi, f and appropriate constants. vf v f
