La unidad de aceleración es en metros por segundo al cuadrado m/s2.

Asi que, primero convertí los km/h a m/s:

50 km/h = 13.889 m/s
20 km/h = 5.556 m/s

Y los sustituís en la fórmula de aceleración:

(a = Δv / Δt). En la misma, “a” es la aceleración, “Av” es la variación de la velocidad y “At” es el tiempo que hay en esa variación.

a = (13.889 - 5.556) / 4 segs
a = 8.333 / 4
a = 2.08325 m/s2

Espero te funcione!

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

Which of these would best describe the outcome of increasing the kinetic energy of the molecules in the above picture?
Lyrx [107]

A) The temperature will increase.

Kinetic energy is the intrinsic energy carried by an object in motion.

Explanation:

Increasing the kinetic energy of the molecules means that molecules rapidly. This causes an increased rate of collision between the molecules and between the molecules and the walls of the container. Most of these collisions are inelastic meaning that some of the energy in the collisions is lost as heat energy to the environment. This means the system becomes hotter.
