When the epiglottis does not function properly this condition can cause?

The role of epiglottis is to   seal off the windpipe while swallowing food.  This will prevent solid substances from entering the respiratory tract. Therefore, in a situation where  the  epiglottis does not function properly, solid substances might enter the windpipe and this might cause chocking

1. (1.2kw)x(15/60hours) = .3kwh --> a

2. (5kw)x(90/60hours)x(8cents/kwh) = $0.60 --> d

3. microwave --> 1200 watts = (1.2kw)x(6/60hours) = .12kwh

coffee-maker --> 900 watts = (.9kw)x(10/60hours) = .15kwh

therefore, it requires more energy for the coffee-maker to do the same amount of work.

so the answer is a.

it's not c. i took the quiz and got it wrong. so my best guess is b.

have a great day, and hope this .
