Answer:

Technician A is correct.

Explanation:

Stroke of the engine means how far is the piston moves during the cycle.It is determined by the crank of the crank shaft. Engine displacement volume  is calculated by multiplying length of the stroke to the piston displacement area.

                          If there are more than one cylinder in the engine, than in that case this number in multiplied by the number of the cylinders inside the engine.

Therefore technician A is correct.

9. In 35 s..a pump delivers 55,000 g of oil into a barrel on a platform 25 m
julia-pushkina [17]
  • The work done by the pump is 13475 J.
  • The power of the pump is 385 W.

<u>Explanation:</u>

When a force causes a body to move work is being done on the object by the force. Work is the measure of energy transfer when a force moves an object through a distance. The work done is the product of mass, gravity, and height.

Work done = m * g * h

                    = 55 * 9.8 * 25

 Work done = 13475 J.

Power is defined as the rate of doing work with time.

 Power = work done / time

             = 13475 / 35

 Power = 385 W.

If you drop a rock off a cliff and it hits the ground 3 seconds later how tall is that cliff
skelet666 [1.2K]

Answer:

Basic kinematics, negating drag and assuming ideal conditions, we use the equation:

d=vi*t+1/2*a*t^2

Since vi is 0 (we know this because you’re dropping it, not throwing it)…

…and the only acceleration acting on it is gravity, a=9.8 m/s^2…

…we get

d=1/2(9.8)(5)^2

Explanation:

Some quick mental math tells us that this is about 125 m.

Plugging it in, we find it to be 122.5 m.
