What are the lower and upper fixed points of a laboratory thermometer in Celsius degrees?
The lower fixed point, or ice point, is the temperature of pure melting ice at normal atmospheric pressure. The upper fixed point, or steam point, is the temperature of pure boiling water at normal atmospheric pressure.
Describe the role that weathering and erosion play in the rock cycle.
Answer:
Weathering is the breaking down or dissolving of rocks and minerals on Earths surface. Once a rock has been broken down, a process called erosion transports the bits of rock and minerals away. Water, acids, salt, plants, animals, and changes in temperature are all agents of weathering and erosion.

Explain one inference scientists made about the interior of the Earth based on seismic waves. Use the words S & P waves in your answer. Use the word refract/bend in your answer
Answer:
"An earthquake radiates P and S waves in all directions and the interaction of the P and S waves with Earth's surface and shallow structure produces surface waves. Near an earthquake the shaking is large and dominated by shear-waves and short-period surface waves." please rephrase this in your own words.

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 drive a car for 2.0 h at 60 km/h, then for another 3.0 h at 85 km/h. What is your average velocity
Answer:
Explanation:
Average velocity is found in the total displacement experienced in the trip divided by the total time it took to make this trip. If, for the first 2.0 hours, the car travels at 60 km/hr, then in 2.0 hours the car can travel 120 km; if it then travels for 3.0 at 85 km/hr, it can travel 255 km in the same direction. The total time this took was 5.0 hours. So doing the math and rounding correctly by following the rules for the adding and subtracting of sig fig's:
[tex]v=\frac{120+255}{5.0}=\frac{380}{5.0}=76\frac{km}{hr}[/tex]
If you do not round when you add, the average velocity is 75 km/hr

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
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.

what happens to the mechanical energy of an apple as it falls from a tree?
Answer:
When the apple falls from the tree, it has some gravitational potential energy due to its height. Now, When it starts falling, the Gravitation Potential energy will starts converting into the Kinetic Energy. When the apple is about to strikes the ground, the Gravitational Potential energy have been converted into the Kinetic Energy.
Explanation:
The potential energy will be low when its kinetic energy is high and vice versa. But the mechanical energy remains conserved.
What is mechanical energy?Mechanical energy can be explained as the sum of kinetic energy and potential energy that can be used to do work. Mechanical energy can be described as the energy of a body due to its motion or position.
The total mechanical energy of a physical system is conserved as the energy can not be created or destroyed. The mechanical energy of a physical system can only be transformed from one form to another when the forces acting work are conservative in nature.
Each force is related to potential energy form and the energy changes between different kinds of potential energy and kinetic energy but the total energy remains constant.
The mechanical energy of the apple remains conserved. As the apple falls its potential energy is converted into kinetic energy.

Explanation:
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.

What is Archimedes principal ?Archimedes' principle states that a body immersed in a fluid is subjected to an upwards force equal to the weight of the displaced fluid.
F(b) = rho*g*V
F(b) = buoyant force
rho = fluid density
g = acceleration due to gravity
V = fluid volume
given
density of raft = 373 kg/[tex]m^{3}[/tex]
volume of raft = 1.43 [tex]m^{3}[/tex]
since, density = mass / volume
mass of raft = density * volume
= 373 * 1.43 = 533.3 kg
using Archimedes principal
Force = density of liquid * volume of liquid displaced * acceleration due to gravity
mg = 1000 * V * 9.8
533.3 * 9.8 = 1000 * V * 9.8
V = 0.5333 [tex]m^{3}[/tex]

The starting temperature of a beaker of water is 60 F. The thermometer shows the temperature of the same beaker of water after being heated on a hot plate. How much higher is the temperature after the water is heated? Record your answer below.
Answer:
The temperature after the water is heated is higher by 152°F
Explanation:
The starting temperature of a beaker of water = 60 F
Temperature of water in heated condition = 212°F
The temperature rises by 212°F - 60°F = 152°F
The temperature after the water is heated is higher by 152°F
