Part C The student's roommate wakes up and turns on in addition to the appliances mentioned in the previous parts the air conditioner (860 W), and he realizes that the room is a mess, so starts to vacuum (630 W). Determine the total rms current in the circuit breaker.

answer: the correct answer is   air pressure at the top of mount everest is higher than at the bottom of the grand canyon.

hope this : )

explanation:

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s
