Tech A says a camshaft position sensor must be positioned correctly to accurately signal the position of the camshaft to the pow

qaws [65]

Answer:

Both Tech A and Tech B

Explanation:

It's important to position sensor accurately to the position of camshaft to the powertrain control in the ignition module as said by Tech A. Equally, to achieve what Tech A says, a special tool can be used for comparing the position of camshaft sensor to crankshaft sensor. Therefore, both technicians are correct.

How will the amount of power change if less work is done in more time?

yKpoI14uk [10]

The amount of power change if less work is done in more time"then the amount of power will decrease".

<u>Option: B</u>

<u>Explanation:</u>

The rate of performing any work or activity by transferring amount of energy per unit time is understood as power. The unit of power is watt

$Power = \frac{Work}{Time}$

Here this equation showcase that power is directly proportional to the work but dependent upon time as time is inversely proportional to the power i.e as time increases power decreases and vice versa.

This can be understood from an instance, on moving a load up a flight of stairs, the similar amount of work is done, no matter how heavy but when the work is done in a shorter period of time more power is required.

A tumbleweed is moving with a velocity of 5.4 m/s westward. A sudden gust of wind blows for 1.5 seconds and reduces its velocity

Klio2033 [76]

Answer:

$a=-2.4 m/s^{2}$

Explanation:

Let's recall the acceleration definition.

$a=\frac{\Delta v}{\Delta t}$ (1)

Δv is the velocity variation, Δv = v(f) - v(i). It is just the difference between final and initial velocities. So Δv = 1.8[m/s] - 5.4[m/s] = -3.6 [m/s]

And Δt is the time variation, in this case it is just 1.5 s.

Therefore, using the equation (1), the acceleration will be:

$a=\frac{-3.6}{1.5}=-2.4 m/s^{2}$

The minus sign means that the tumbleweed is slowing down.

I hope it helps you!

A particle moves along a straight line such that its position is defined by s = (t^3- 3t^2 2) m. Determine the average velocity,

sergey [27]

From the information in the question, the velocity of the particle is 24 ms-1.

Let us recall that the velocity of a body is obtained as the first derivative of distance covered with respect to time. Hence;

ds/dt = v

Now, we have to differentiate (t^3- 3t^2 + 2)m with respect to t and we have;

d(t^3- 3t^2 + 2)m/dt = 3t^2 - 6t

Now at t= 4s, the velocity of the particle is;

3(4)^2 - 6(4) = 24 m/s

The acceleration of the particle is the second derivative of distance with respect to time;

d^2s/dt^2 = d^2 3t^2 - 6t/dt^2 = 6t

Substituting t = 4s

a = 24 ms-2
