The factor related to ride comfort would be least likely to be used in a benefit-cost analysis of electric vehicles.

Answer: Option D

<u>Explanation: </u>

The electric vehicles are the best alternative to traditional internal combustion vehicles. The electric vehicles have advantages of no hazardous emission of fuel, no fuel cost and so the fuel economy will be maintained.

The benefit-cost analysis is the ratio of benefits attained by the consumer, producer and society in terms of saving of different expenses like fuel, pollution etc. to the production and buying cost of the vehicle.

In traditional internal combustion vehicle, the benefit to cost analysis ratio is around 0.7 and the electric vehicles reach this ratio after many changes. But the comfort of the ride is not included in the analysis of benefit-cost ratio.

a light wave is traveling straight up out of the ocean then moves out into the air how do you expect the movement of the light w

Mariulka [41]

If the light is traveling straight up, then it hits the interface (surface
or boundary) between water and air perpendicularly (90° to the surface).

This direction is the direction of the 'normal' to the surface. So the
angle of incidence is zero, and that means the angle of refraction is
also zero. The light just keeps going in the same direction when it
emerges into the air, and is not bent.

However, its speed increases in air, and that means its wavelength
also becomes longer than it was in the water.

bogdanovich [222]

Answer:

speed is 81.03 mph

direction is N 3.58 W

Explanation:

given data

travel north = 70 mph

Stream current = 12 mph

direction = S 25° E

result due north = 70 mph

to find out

speed and direction

solution

we will get component of resultant that is

v cosθ and v sinθ

( 12cos295 , 12 sin295 ) at ( 0, 70)

as that we can say

v sinθ + 12sin295 = 70 ....................1

v cosθ + 12 cos295 = 0 ......................2

vcosθ = -5.0714

vsinθ = 80.8756

now by ratio

cosθ /sinθ = -5.0714/ 80.8756

cot θ = -0.0627

θ = 93.58

so direction is N 3.58 W

and

we know

vcosθ = - 12cos295

v = - 12cos295 / cos(93.58)

v = 81.03 mph

so speed is 81.03 mph
