The equation for velocity is distance/time.. So if it goes 100m in 4 seconds.. It's 100/4 which equals 25 mls north. (Velocity includes the direction in the answer)

The velocity is 25 because you just divide 100/4

An engineer in a locomotive sees a car stuck on the track at a railroad crossing in front of the train. When the engineer first
GarryVolchara [31]

Answer:

The right answer is "1.369 m/s²".

Explanation:

The given values are:

Distance (s)

= 260 m

Initial speed (u)

= 26 m/s

Reaction time (t')

= 0.51 s

During reaction time, the distance travelled by locomotive will be:

⇒  s'=ut'

        =26\times 0.51

        =13.26 \ m

Remained distance between locomotive and car:

⇒  x=s-s'

         =260-13.26

         =246.74 \ m

Now,

The final velocity to avoid collection is, V = 0 m/s

From third equation of motion:

⇒  V^2=u^2+2ax

On putting the estimated values, we get

⇒  0=(26)^2+2\times a\times 246.74

⇒  0=676+493.48a

⇒  493.48a=-676

⇒            a=-\frac{676}{493.48}

⇒            a=1.369 \ m/s^2

An object is placed 10 cm in front of a diverging mirror. What is the focal length of the mirror if the image appears 2 cm behin
Dafna1 [17]

Answer:

the focal length of the mirror is :  f=-2.5\,\,cm

Explanation:

Use the formula for the formation of image using a divergent mirror and recalling that the image (s') that this mirror formed is virtual, so it is entered as a negative number in the formula. Use the object position (s) as 10, the image position (s') as -2, and derive the value of the focal length:

\frac{1}{s} +\frac{1}{s'}=\frac{1}{f}\\\frac{1}{10} +\frac{1}{-2}=\frac{1}{f}\\\frac{1}{10} -\frac{1}{2}=\frac{1}{f}\\\frac{10\,f}{10} -\frac{10\,f}{2}=\frac{10\,f}{f}\\f-5\,f=10\\-4\,f=10\\f=-2.5\,\,cm

What quantity is multiplied by the hydraulic lift system of a dump truck?
kogti [31]

funny, actually, i'm a hydraulic, and pneumatic cylinder, pump, and line system mechanic, and the answer is pressure.... pressure builds up from the hydraulic pump, and then transfers through hoses to extend, and contract the cylinders by filling them with hydraulic fluid, and vice versa for contracting them.

hope this helps!
