Una barra de plata de 335.2 g con una temperatura de 100 ºC se introduce un calorímetro de aluminio de 60 g de masa que contiene 450 g de agua a 23 ºC. Sr agita la mezcla y la temperatura se incrementa hasta 26 ºC. ¿Cuál es el calor especifico de la plata?

Answers

Respuesta:

0,0560 cal / gºC.

Explicación:

Cantidad de calor; (Q)

Q = mcΔt; Δt = t2 - t1

m = masa, c = capacidad calorífica específica; Δt = cambio de temperatura

c de agua = 1 cal / gºC

c de aluminio = 0,22 cal / gºC

QTotal = Q de agua + Q de aluminio

Q de agua = 450 * 1 * (26 - 23) = 1350 cal

Q de aluminio = 60 * 0.22 * (26 - 23) = 39.6 cal

QTotal = 1350 + 39,6 = 1389,6 cal

Calor perdido = calor ganado

QTotal = calor perdido

- 1389,6 = 335,2 * c * (26 - 100)

-1389,6 = −24804,8 * c

c = 1389,6 / 24804,8

c = 0,056021 cal / gºC.

Capacidad calorífica específica de la plata = 0,0560 cal / gºC.

An elephant's legs have a reasonably uniform cross section from top to bottom, and they are quite long, pivoting high on the animal's body. When an elephant moves at a walk, it uses very little energy to bring its legs forward, simply allowing them to swing like pendulums. For fluid walking motion, this time should be half the time for a complete stride; as soon as the right leg finishes swinging forward, the elephant plants the right foot and begins swinging the left leg forward.

On a cold day, the speed of sound in air is 330 m/s. A note with a frequency of 1,320 Hz is played on an instrument. What is the wavelength of that sound wave? 0.25 m 4 m 1,650 m 435,600 m

Answers

Answer:

0.25 m

Explanation:

Given that,

The speed of sound, v = 330 m/s

The frequency of the note of the instrument, f = 1320 Hz

We need to find the wavelength of the sound wave.

We know that,

Wavelength, [tex]\lambda=\dfrac{v}{f}[/tex]

Put all the values,

[tex]\lambda=\dfrac{330}{1320}\\\\\lambda=0.25\ m[/tex]

So, the wavelength of the sound wave is equal to 0.25 m.

Un móvil parte desde un punto ubicado a +10 Km del origen ,se mueve en línea recta llegando hasta el Km 60, donde cambia su sentido de movimiento, regresando al Km 32 .Entonces el desplazamiento o cambio de posición y la distancia recorrida son respectivamente: A) 22 km y 78 km B) -22 km y 78 km C) -18 km y 38 km D) -18 km y 18 km E) 10 km y 32 km

Answers

Answer:

La opción correcta es la A) 22 km y 78 km.

Explanation:

Dado que el desplazamiento (D) es un vector, su valor viene dado por la suma algebraica de los vectores del desplazamiento de ambos tramos.

Como en el primer tramo movil se mueve en la dirección de x-positiva y en el segundo tramo se mueve en el sentido de x-negativo, tenemos:

[tex] D = (60 km - 10 km) - (60 km - 32 km) = 22 km [/tex]  

Ahora, la distancia (d) es una magnitud escalar, por lo que su valor viene dado por la suma del desplazamiento de ambos tramos:

[tex] d = (60 km - 10 km) + (60 km - 32 km) = 78 km [/tex]                

Por lo tanto, la opción correcta es la opción A) 22 km y 78 km.

Blue-ray disc accelerates from rest to a constant rotational speed of 466 rpm, it rotates through an angular displacement of 0.250 rev. What is the angular acceleration of the CD?

Answers

Answer:

[tex]\alpha =434312\ rev/s^2[/tex]

Explanation:

Given that,

Initial angular speed, [tex]\omega_i=0[/tex]

Final angular speed, [tex]\omega_f=466\ rpm[/tex]

Angular displacement, [tex]\theta=0.25\ rev[/tex]

We need to find the angular acceleration of the CD. Using third equation of rotational kinematics as follows :

[tex]\omega_f^2-\omega_i^2=2\alpha \theta\\\\\alpha =\dfrac{\omega_f^2-\omega_i^2}{2\theta}\\\\\alpha =\dfrac{466^2-0^2}{2\times 0.25}\\\\\alpha =434312\ rev/s^2[/tex]

So, the angular acceleration of the CD is equal to [tex]434312\ rev/s^2[/tex].

Explanation:

It is false that one cannot classify matter based on chemical properties.

What is a matter?

Matter is the scientific term for any type of material. Matter is defined as anything with mass that occupies space.

Matter requires at least one subatomic particle, though most matter is made up of atoms. A pure substance is sometimes referred to as matter.

Solids, liquids, and gases are the three forms or phases of matter. A substance is defined as matter that is homogeneous and has identical parts.

Substances are classified as either elements or compounds. Elements are pure substances that cannot be chemically decomposed into simpler substances.

Chemically, matter can be classified as pure substance elements and compounds, mixture, or impure substance.

Thus, the given statement is false.

Luna and Angela are competitors in a running competition. Both are leading the race and enter at the same time the last 30 meters. Angela enters the final segment runnning at 4 m/s and "applies" an acceleration of 2 m/s2 while Luna enters the final segment at 3m/s but "applies " an acceleration of 3 m/s2. (a) Who finishes the race first? (Do the calculations) (b) Who is running faster at the end of the race?

Answers

Answer:

(a) Luna

(b) Luna

Explanation:

(b)

The final speed can be found by using the third equation of motion:

[tex]2as = v_f^2 - v_i^2\\[/tex]

where,

a = acceleration

s = distance covered

vf = final speed

vi = initial speed

For Angela:

a = 2 m/s²

s = 30 m

vi = 4 m/s

vf = v_fa

therefore,

[tex]2(2\ m/s^2)(30\ m) = (v_{fa})^2 - (4\ m/s)^2\\v_{fa}^2 = 120 m^2/s^2 + 16\ m^2/s^2\\v_{fa} = 11.66\ m/s\\[/tex]

For Luna:

a = 3 m/s²

s = 30 m

vi = 3 m/s

vf = v_fl

therefore,

[tex]2(3\ m/s^2)(30\ m) = (v_{fa})^2 - (3\ m/s)^2\\v_{fa}^2 = 180 m^2/s^2 + 9\ m^2/s^2\\v_{fa} = 13.74\ m/s\\[/tex]

Therefore, Luna will be running faster at the end of the race.

(b)

To calculate the time of completion we will use the first equation of motion:

[tex]v_f = v_i + at[/tex]

FOR ANGELA:

[tex]11.66\ m/s = 4\ m/s + (2\ m/s^2)t_a\\t_a = \frac{7.66\ m/s}{2\ m/s^2}\\\\t_a = 3.83\ s[/tex]

FOR LUNA:

[tex]13.74\ m/s = 3\ m/s + (3\ m/s^2)t_l\\t_l = \frac{10.74\ m/s}{3\ m/s^2}\\\\t_l = 3.58\ s[/tex]

Hence, LUNA finishes the race first.
