29) A load is placed on a 1.5-kg cart. A force of
6.0 N [left] causes the cart and its load to have
an acceleration of 3.0 m/s" [left]. What is the
mass of the load?

Answer:

Density=Mass/Volume

            =20/4 kg/m^3

            =5 kg/m^3

Answer:

it begins to move to the right! :)

Explanation:

the PE = Weight x g x Height above ground where g is the gravitational constant (9.8m/s^2)

so tge PE = 100 x 9.8 x 25 = 24500 J

Answer:

Cannot see all the answer choices but, when pressure goes up, volume goes down. So your best bet is to choose the graph that has a downward slant.

Answer:

Distancia, S = 2.84 metros

Explanation:

Dados los siguientes datos;

Velocidad inicial = 55 m/s

Velocidad final = 115 m/s

Deceleración = 14500 m/s²

Para encontrar qué tan lejos viajaría el automóvil, usaríamos la tercera ecuación de movimiento;

V² = U² + 2aS

115² = 55² + 2*14500*S

13225 = 3025 + 29000S

29000S = 13225 - 3025

29000S = 10200

S = 29000/10200

Distancia, S = 2.84 metros

Answer:

a) La fuerza que se aplica al pistón de entrada tiene una magnitud de 1968.75 newtons.

b) La presión que se aplica al pistón de entrada es de 111408.460 pascales.

Explanation:

a) Este problema se resuelve mediante el Principio de Pascal, el cual establece que la presión dentro de un sistema hidráulico cerrado es la misma en cualquiera de sus puntos. Por tanto, podemos calcular la fuerza aplicada al pistón de entrada mediante la siguiente relación:

[tex]\frac{F_{in}}{\frac{\pi}{4}\cdot D_{in}^{2}} = \frac{M\cdot g}{\frac{\pi}{4}\cdot D_{out}^{2} }[/tex]

[tex]F_{in} = \left(\frac{D_{in}}{D_{out}} \right)^{2}\cdot M\cdot g[/tex] (1)

Where:

[tex]F_{in}[/tex] - Fuerza aplicada al pistón de entrada, en newtons.

[tex]D_{in}[/tex] - Diámetro del pistón de entrada, en metros.

[tex]D_{out}[/tex] - Diámetro del pistón de salida, en metros.

[tex]M\cdot g[/tex] - Peso del carro, en newtons.

Si sabemos que [tex]D_{in} = 0.15\,m[/tex], [tex]D_{out} = 0.40\,m[/tex] y [tex]M\cdot g = 1.4\times 10^{4}\,N[/tex], entonces la fuerza aplicada al pistón de entrada es:

[tex]F_{in} = \left(\frac{0.15\,m}{0.40\,m} \right)^{2}\cdot (1.4\times 10^{4}\,N)[/tex]

[tex]F_{in} = 1968.75\,N[/tex]

La fuerza que se aplica al pistón de entrada tiene una magnitud de 1968.75 newtons.

b) Ahora, presión aplicada al pistón de entrada ([tex]p[/tex]), en pascales, queda descrita a través de la siguiente expresión:

[tex]p = \frac{F_{in}}{\frac{\pi}{4}\cdot D_{in}^{2} }[/tex] (2)

Si sabemos que [tex]F_{in} = 1968.75\,N[/tex] y [tex]D_{in} = 0.15\,m[/tex], entonces la presión aplicada al pistón de entrada es:

[tex]p = \frac{1968.75\,N}{\frac{\pi}{4}\cdot (0.15\,m)^{2} }[/tex]

[tex]p = 111408.460\,Pa[/tex]

La presión que se aplica al pistón de entrada es de 111408.460 pascales.

Answer:

4Al + 3Mno2 --> 2Al2o3 + 3Mn

Explanation:

Al = 1 x 4 = 4

Mn = 1 x 3 = 3

O = 2 x 3 = 6

Al = 2 x 2 = 4

Mn  = 1 x 3 = 3

Answer:

a thermos is designed to keep hot things hot by not allowing heat to escape.

Explanation:

A thermos is a bottle with a double-walled container inside of it. The air between the two walls is sucked out during construction, creating a vacuum.

Answer:

a) A = 3 cm,  b)  T = 0.4 s,   f = 2.5 Hz,

2) A standing wave the displacement of the wave is canceled and only one oscillation remains

Explanation:

a) in an oscillatory movement the amplitude is the highest value of the signal in this case

          A = 3 cm

b) the period of oscillation is the time it takes for the wave to repeat itself in this case

          T = 0.4 s

the period is the inverse of the frequency

         f = 1 /T

         f = 1 /, 0.4

         f = 2.5 Hz

2) a traveling wave is a wave for which as time increases the displacement increases, in the case of a transverse wave the oscillation is perpendicular to the displacement and in the case of a longitudinal wave the oscillation is in the same direction of the displacement.

A standing wave occurs when a traveling wave bounces off some object and there are two waves, one that travels in one direction and the other that travels in the opposite direction. In this case, the displacement of the wave is canceled and only one oscillation remains.

Answer:

Por que existe una relación entre dichas magnitudes.

Para un pendulo perfecto de largo L, sabemos que el periodo esta definido como:

[tex]T = 2*\pi *\sqrt{L/g}[/tex]

Donde:

pi = 3.14

L = largo del péndulo

g = aceleración gravitatoria = 9.8 m/s^2

Entonces podemos ver que el periodo es proporcional a la raíz cuadrada de la longitud del péndulo.

Esto es por lo que al analizar datos de un experimento se debería observar una relación entre esas magnitudes.

Answer:

The centripetal force increases.

Explanation:

Centripetal force is given by [tex]F_c=ma_c[/tex]; where [tex]a_c=\frac{v^2}{r}[/tex].

Given these two equations, we can rewrite the formula for centripetal force as:

[tex]F_c=m\frac{v^2}{r}[/tex]

As shown, radius is in the denominator, thus, a smaller radius would lead to a larger centripetal force.

Explanation:

The buoyant force acting on an immersed body is equal to the weight of the fluid displaced by it, if the fluid is in rest. In this case, the fluid is accelerating upwards so the buoyant force must also provide the displaced fluid force to accelerate. Therefore, buoyant force will be fVρgeff where V = volume of body and f = fraction of volume of body immersed in fluid and geff=g+a=1.5g.

Answer:

Stimulants are a group of drugs that result in increased activity in the body. Sometimes referred to as “uppers,” these drugs are frequently abused due to their performance-enhancing and euphoric effects. Generally, those who abuse stimulants experience heightened energy levels and enhanced focus.

Stimulants speed up mental and physical processes, which can produce desirable effects in the short-term by increasing levels of dopamine in the brain. While users may feel great due to the short-term effects of stimulants, long-term abuse of these drugs can have significant consequences, which is why it is so important for those who abuse the drugs to get help as quickly as possible.
