By definition, we have to:

E = IZ

Where,

E: voltage

I: current

Z: Resistance

To calculate the voltage value, we must replace the following values in the given equation:

I = 3 + 2i\\Z = 2 - i

We have then:

E = (3 + 2i) (2 - i)

Making the product of complex numbers we have:

E = (3 * 2 - 3i) + (4i - 2i ^ 2)\\E = (6 - 3i) + (4i - 2 (-1))\\E = (6 - 3i) + (4i +2)

E = (6 + 2) + (4-3) i\\E = 8 + i

Answer:

the voltage of the circuit is:

E = 8 + i

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

A 4kg rock isn’t rolling 10m/s. Find it’s kinetic energy.
scoundrel [369]

Kinetic energy = (1/2) (mass) (speed)²

The rock's kinetic energy is not 

                           (1/2) (4 kg) (10 m/s)²

                      =   (1/2) (4 kg) (100 m²/s²)

                      =         200 Joules .

It may be more, or it may be less.  The only thing
we can be sure of is that it is not 200 Joules.
