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.

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.

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.

the atomic mass unit (amu) is
a. the mass of a single atom of carbon
b. one millionth of a gram
c. approximately the mass of a proton
d. approximately the mass of an electron
(dont send me a link please)
Answer:
The correct option is (a).
Explanation:
One Atomic mass unit is the mass of an atom. It is defined as the mass of a single carbon -12 at rest.
The relation between amu and kg is given by :
[tex]1\ amu=1.66\times 10^{-27}\ kg[/tex]
Hence, one amu is equal to the mass of a single atom of carbon.
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

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.

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 8.8-magnitude earthquake in Chile in 2010 killed more than 700 people. On January 12, 2010, a less powerful earthquake, measuring 7.0, killed more than 200,000 in Haiti. Why do you think this happened?
Answer:
The main reason for this is the engineering and technology driven building construction in Chile than in Haiti
Explanation:
The main reason for this is the engineering and technology driven building construction in Chile than in Haiti. Most of the buildings in Haiti do not fit in the building byelaws norms as most of them were constructed in a short period of time with less engineering and at cheaper rate. While building in Chile were built adhering to the building codes and byelaws.
The base of the building is Chile were separated from each other using the “base isolation” technology and the were also more flexible as compared to the buildings in Haiti.
The skyscrapers in Chile were constructed in a way that they can float on the arrangements of ball bearings and padded cylinders

A negative charge of 4.0 x 10 C and a positive charge of 7.0 x 10 C are separated by 0.15 m. What is
the force between the two charges?
Answer:
112×10^12N
Explanation:
We use the following equation to find the force between two charges that are away from each other at a particular distance:
F=k×q1×q2/r^2 F=9×10^9×4×10×7×10/(0.15)^2 F=252×10^11/0.225 F=1120×10^11=112×10^12a pine raft (density = 373 kg/m^3) has a volume of 1.43 m^3. How much of the raft's volume is below the water line? Unit is m^3

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
