cupoosta [38]

Answer:

  Tech B

Explanation:

Bleeding the master cylinder on the bench does nothing for the air in the brake lines on the vehicle. The bench bleeding is a preferred first step, but bleeding the rest of the brake system is also required. A final check of proper operation on the vehicle should also be accomplished.

Tech B is correct.

A European car manufacturer reports that the fuel efficiency of the new MicroCar is 48.5 km/L highway and 42.0 km/L city. What a
statuscvo [17]

Answer:

Fuel efficiency for highway = 114.08 miles/gallon

Fuel efficiency for city = 98.79 miles/gallon

Explanation:

1 gallon = 3.7854 litres

1 mile = 1.6093 km

Let's first convert the efficiency to km/gallon:

48.5 km/litre = (48.5 * 3.7854) km/gallon

48.5 km/litre =  183.5919 km/gallon (highway)

42.0 km/litre = (42.0 * 3.7854) km/gallon

42.0 km/litre = 158.9868 km/gallon (city)

Next, we convert these to miles/gallon:

183.5919 km/gallon = (183.5919 / 1.6093) miles/gallon

183.5919 km/gallon = 114.08 miles/gallon (highway)

158.9868 km/gallon = (158.9868 /1.6093) miles/gallon

158.9868 km/gallon = 98.79 miles/gallon (city)

E total kinetic energy of a 2500 lbm car when it is moving at 80 mph (in BTU)?
Galina-37 [17]

Answer:

KE= 687.21 BTU

Explanation:

Given that

Mass of car = 2500 lbm

We know that 1 lb=0.45 kg

So the mass of car  m =1133.98 kg

Velocity of car= 80 mph

We know that 1 mph =0.44 m/s

So velocity of car = 35.76 m/s

As we know that kinetic energy (KE) is given as follows

KE=\dfrac{1}{2}mv^2

Now by putting the values

KE=\dfrac{1}{2}\times 1133.98\times 35.76^2

KE=725.05 KJ

We know that   1 KJ = 0.94 BTU

So  KE= 687.21 BTU
