With what average speed must you drive your car if your average speed for the entire 23 km is to be 25 km/h?

Answer:

25km/h

Explanation:

This is a trick question, the average speed in this case does not really depend on calculation or extrapolation, it just refers to an event that is yet to occur,

In other words, if you want to achieve an average speed of 25km/h for 23km, then you should drive your car at a constant speed of 25km/h, any variation in speed may cause a change in your average speed at the end.

A 500-N weight sits on the small piston of a hydraulic machine. The small piston has area 2.0 cm2. If the large piston has area
weqwewe [10]

Answer:

W₂= 10000 N

Explanation:

Pascal´s Principle can be applied in the hydraulic press:

If we apply a small force (F1) on a small area piston A1, then, a pressure (P) is generated that is transmitted equally to all the particles of the liquid until it reaches a larger area piston and therefore a force (F2) can be exerted that is proportional to the area (A2) of the piston:

Pressure is defined as the force (F) applied per unit area (A)

P=F/A   (N/m²)

P1=P2

\frac{F_{1} }{A_{1} } = \frac{F_{2} }{A_{2} }

F_{2} = \frac{F_{1}*A_{2}  }{A_{1}}  Equation (1)

Data

W₁ = weight sits on the small piston

F₁ = W₁= 500 N

A₁ = 2.0 cm²

A₂ = 40 cm²

Calculation of the weight  (W₂) can the large piston support

We replace data in the equation (1)

F_{2} = \frac{(500)*(40) }{2}

F₂ = 10000 N

W₂= F₂= 10000 N

Kiley went 5.7 km/h north and then went 5.8 km/h west. From start to finish, she went 8.1 km/h northwest.
avanturin [10]
5.7 km/h north and 5.8 km/h west are instantaneous velocities, while 8.1 km/h northwest is the average velocity.<span>

The answer choice above is correct.

The instantaneous velocities are the actual </span>velocities while traveling ( the velocity during that instant ). The average velocity is the average of the instantaneous velocities ( the speed in one direction equivalent to the two speeds <span>in different directions ).

I used speed in the explanation because velocity is speed with direction.</span>
