Answer:

Explanation:

There are many factors in which company will fail.

1- It is not possible to have wind every time while car is on road.

2- If the wind suddenly stops in middle of road, the car will also not move.

3- Wind might not be much powerful enough to move the car.

4- There is no such system that can ever give 100 percent output.

EVEN IF they can build such a machine, it's not too useful.

-- If the wind starts and stops, your car would do the same thing.

-- If the wind isn't blowing at all, your car is going nowhere. (and fast)

-- You could never move along the road faster than the wind is moving along the road.

-- You could never move in the direction towards where the wind is coming from.  This has been proven before, with the technological marvel known as the "sailboat".

Call your broker immediately.  Tell him you do NOT want to buy any stock in CarCompany.

A transformer has two sets of coils, the primary with N1 = 160 turns and the secondary with N2 = 1400 turns. The input rms volta
vovikov84 [41]

To solve the problem it is necessary to apply the concepts related to the voltage in a coil, through the percentage relationship that exists between the voltage and the number of turns it has.

So things our data are given by

N_1 = 160

N_2 = 1400

\Delta V_{1rms} = 62V

PART A) Since it is a system in equilibrium the relationship between the two transformers would be given by

\frac{N_1}{N_2} = \frac{\Delta V_{1rms}}{\Delta V_{2rms}}

So the voltage for transformer 2 would be given by,

\Delta V_{2rms} = \frac{N_2}{N_1} \Delta V_{1rms}

PART B) To express the number value we proceed to replace with the previously given values, that is to say

\Delta V_{2rms} = \frac{N_1}{N_2} \Delta V_{1rms}

\Delta V_{2rms} = \frac{1400}{160} 62V

\Delta V_{2rms} = 1446.66V

A nuclear accident (intentional or unintentional) can cause significant harm to those living nearby or at a distance. Harmful le
Vladimir [108]

Answer:

(C) Contact

Explanation:

Radiation Poisoning is a horrific disease that is transmitted in many ways. After a nuclear accident radiation is released into the atmosphere becoming airborne and affecting everyone that breathes it in. It is also transmitted in droplets from acid rainfall. Once the gamma radiation penetrates the body of a person it can contaminate other people by having skin to skin contact with the person that is contaminated. Therefore it can be prevented by having precaution of direct contact with anyone contaminated.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

To withstand ‘g-forces’ of up to 10 g’s, caused by suddenly pulling out of a steep dive, fighter jet pilots train on a ‘human ce
Marina86 [1]

Answer:

34.292 m/s

Explanation:

When plane dives the gravitational acceleration becomes 10 times extra i-e

acceleration a = g= 10g's=10 ×9.8= 98 m/sec2

radius of dive circle = 12 m

v= speed= ?

Using

a= \frac{v^{2} }{r}

==> v^{2} = a × r = 98 × 12 = 1176 (\frac{m}{s}) ^{2}

==> v= \sqrt{1176(\frac{m}{s} )^{2} }

==> v= 34.292 m/s

Find the voltage drop (in volt) along a 93.4 meter long 10 gauge copper wire carrying acurrent of 72.5 A. The diameter of a 10 g
Sophie [7]

Answer: 5.41 V

Explanation:in order to explain this result we have to use the Ohm law given by:

ΔV=R*I where R is the resistance which is equal R= ρ*L/A . ρ is the resistivity, L the length of the wire and A is the cross section. I is the current.

Then we have

ΔV=ρ*L*I/A= 1.68 * 10^-8 Ωm*93.4 m*72.5A/2.1* 10^-5 m^2=5.41 V
