Explanation:
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?
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.

Amy pulls a spring with a spring constant k = 100 stretching it from its rest length of 0.10 m to 0.2
Answer:
Elastic potential energy E = 0.5 J
Explanation:
Let us assume we have to find the elastic potential energy stored in the spring.
Given: k = 100
change in the length of the spring x = 0.2-0.1 = 0.1 m
Elastic potential energy
E = [tex]\frac{1}{2} kx^2[/tex]
plugging the values we get
[tex]E = 0.5\times100\times0.1^2\\=0.5 J[/tex]
Hence, Elastic potential energy E = 0.5 J
Amy pulls a spring with a spring constant k = 100 N/m, stretching it from its rest length of 0.10 m to 0.20 m.
What is the elastic potential energy stored in the spring?
Answer: 0.5 J
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?
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.
You cannot classify matter based on chemical properties. true or false?
Answer:
ture i think
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.

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?
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].

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
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.

An object moves from point A to B to C to D and finally to A
along the circle shown in the figure below.
a) Find the distance covered by the moving object.
b) Find the magnitude of the displacement of the object.
Answer:
a) The distance covered by the moving object is approximately 18.85 km
b) The magnitude of the displacement of the object is 0 (no displacement)
Explanation:
From the drawing, we have;
The sale of the drawing is 1 unit = 1 km
The radius of the circle in the drawing along which the object moves = 3 units
Therefore;
The radius of the circle along which the object moves, r = 1 km/unit × 3 units = 3 km
a) The distance covered by the object that moves from point A to B to C to D and finally to A is equal to the circumference of the circle
Therefore;
The distance covered by the moving object, d = 2·π·r
By pugging the value for r = 3 km
d = 2 × π × 3 km = 6·π km ≈ 18.85 km
The distance covered by the moving object, d ≈ 18.85 km
b) The displacement = The object's change in position
The initial position of the object = Point A
The final position of the object = Point A
Therefore, the displacement of the object, A = No displacement = 0 (No difference between the initial and final location of the object
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.
