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.

What is the ACCELERATION of a 50 kg object pushed with a force of 500 newtons *

Anon25 [30]

Answer:

The answer is

Explanation:

To find the acceleration of an object given the force and mass we use the formula

<h3> $acceleration = \frac{force}{mass}$ </h3>

From the question

mass of object = 50 kg

force = 500 N

So the acceleration is

<h3> $acceleration = \frac{500}{50} \\ = \frac{50}{5}$ </h3>

We have the final answer as

Hope this helps you

a baseball is hit 3 feet above ground level at 100 feet per second and at an angle of 45 with respect to the ground. (g=32 feet/

LiRa [457]

Answer:

hmax=81ft

Explanation:

Maximum height of the object is the highest vertical position along its trajectory.

The vertical velocity is equal to 0 (Vy = 0)

$0=V_{y}-g*t=v_{0}*sin(\alpha)-g*th\\$

we isolate th (needed to reach the maximum height hmax)

$th = \frac{v_{0}*sin(\alpha)}{g}$

The formula describing vertical distance is:

$y = Vy * t-g* t^{2} / 2$

So, given y = hmax and t = th, we can join those two equations together:

$hmax = Vy* th-g*th^{2}/2$

$hmax =Vo^{2}*sin(\alpha )^{2}/(2*g)$

if we launch a projectile from some initial height h all you need to do is add this initial elevation

$hmax =h+Vo^{2}*sin(\alpha)^{2}/(2*g)$

$hmax =3+100^{2}*sin(45)^{2}/(2 * 32)=81 ft$

Which ball has the greater average speed during the 1-s interval after release (assuming neither hits the ground during that tim

notka56 [123]

Answer:

The ball thrown downward

Explanation:

When the ball is thrown vertically, the acceleration of it is the gravity acceleration independent if it is thrown downward or upward. However, the acceleration is a vector, so, when the ball is thrown upward, the movement is against the gravity, so the acceleration is negative, and so, the velocity decreases during time; and when the ball is thrown downward, the movement goes to the gravity, so the acceleration is positive, so the velocity increase after time passes.

Where is the fulcrum of a broom?

algol [13]

It's one of your hands. Which one it is depends on how you sweep.

-- If you hold the top of the stick motionless and wave your bottom hand
back and forth, then your top hand is the fulcrum, and you're using the
broom as a Class-3 lever.

-- If you hold your bottom hand motionless and wiggle the top end of the
broom back and forth with your top hand, then your lower hand is the fulcrum,
and you're using the broom as a Class-1 lever.
