An airplane weighing 11,000 N climbs to a
Gennadij [26K]

The power in horsepower is 40.1 hp

Explanation:

We start by calculating the work done by the airplane during the climb, which is equal to its change in gravitational potential energy:

W=(mg)\Delta h

where

mg = 11,000 N is the weight of the airplane

\Delta h = 1.6 km = 1600 m is the change in height

Substituting,

W=(11,000)(1600)=17.6\cdot 10^6 J

Now we can calculate the power delivered, which is given by

P=\frac{W}{t}

where

W=17.6\cdot 10^6 J is the work done

t=9.8 min \cdot 60 = 588 s is the time taken

Substituting,

P=\frac{17.6\cdot 10^6 J}{588}=2.99\cdot 10^4 W

Finally, we can convert the power into horsepower (hp), keeping in mind that

1 hp = 746 W

Therefore,

P=\frac{2.99\cdot 10^4}{746}=40.1 hp

Your science teacher presents you with a circuit model that contains five light bulbs, a switch, and a 1.5-volt battery. The wir
harkovskaia [24]

Answer: i'm not fully sure but i think it's A.

Explanation: why do i think the answer is a? well the parallel circuit definition is a closed circuit in which the current divides into two or more paths before recombining to complete the circuit. which means that if you unscrew/remove one bulb it would still work, but in a series circuit it will not work, because if you remove one it turns all the bulbs off.
