_____ waves are Longitudinal waves caused by an earthquake!
(the last person spammed it) PLZ help
Compressional waves
Explanation:
(longitudinal, primary, P-waves of earthquake seismology) are the fastest of all seismic waves. They propagate by compressional and dilatational uniaxial strains in the direction of wave travel through solid, liquid, and gas media.
Answer:
An earthquake generates a series of seismic waves that travel through the interior or near the surface of the Earth. ... They're compressional or longitudinal waves that push and pull the ground in the direction the wave is traveling. They usually cause very little damage.

If you had a notebook and a pencil on the a table, what would happen if they were both to fall off
A. The mass of objects would be similar
B. Gravity would pull them to the ground.
C. The acceleration of these two objects would be different for both
D. Gravity would make the notebook fall sooner because it is heavier
Answer: b
Explanation:
If someone showed you two spheres of the same size but with different masses, say 1g and 10kg, and asked which would hit the ground first after being dropped from the Leaning Tower of Pisa, what would you say? If you’re like most people, you would say the 10kg sphere would hit the ground first. Aristotle said so too, and for 1,000 years everyone believed him. But doing the experiment would show you, besides a great view of Pisa, that in fact, both spheres hit the ground at the same time.This is exactly what Galileo did, showing the world that objects of different masses fall at the same rate. (This is also a good example of why it is important to do experiments yourself and not to just take someone else’s word for it.) To start understanding why Galileo was right, we need to understand the difference between several physics words that are often jumbled together and confused: mass, weight, speed, velocity, acceleration, and force.
Temperature is a measure of the average speed of the ____ of a thing.

Consider these scenarios.
Scenario 1- Your ear is resting on the end of a metal bar that is stuck by a drumstick about 7 meters away from your ear.
Scenario 2- You are about 7 meters away from a metal bar that is struck with a drumstick. The sound travels through the air to your ear.
In which of these scenarios would the sound of the drumstick hitting the metal bar get to you in the least amount of time? Explain your answer.
Answer:
The sound of the drumstick hitting the metal bar will get to me in a shorter amount of time in Scenario 1. The sound wave will travel faster in the metal bar than through the air because the speed of sound waves in solids is faster than it is in gases.
Explanation:
The sound will reach my ear in a shorter time in Scenario 1 because sound travels faster through the metal bar than through the air. The speed of sound waves in solids is faster than it is in gases.

2011:
Graph (see next page for graph paper grid)
Using the data from the Coal Production Table, create a graph of coal usage in each region over the years. The x-axis should be years, and the y-axis should be coal production. Use a different symbol or color to represent each region. Remember to include titles and labels.
Scan or take a picture of your graph and submit it with your assignment.
Analysis
Changes over time are called trends. You can see on the graph a downward trend in the Appalachian and Interior regions and an upward trend in the Western region.
Try predicting future coal production. Using a ruler, draw the lines for each region. Go beyond 2011. Draw the line with the same pattern it follows on the graph. The extension of the lines is based on what you predict will happen with coal production.
Questions
1. How much coal will be produced in the year 2020 for each region?
2. What trend would you predict for the next ten years for each region?
3. If people keep using coal in the same way, scientists say there may be enough coal reserves to last 200 to 300 years. Does your graph show trends that match what scientists say? What kinds of factors might cause them not to match?
4. Can you think of any problems that could come from using only 15 years of data to predict trends for the next 100 years? Explain your answer. How could you prevent some of these problems?

A topographic map helps architects to find the elevation of a building site. Plant roots hold the soil in place and helps prevent erosion. The term deposition is used means laying down of sediments.
Satellite views help scientists they give scientists the ability to predict catastrophic events.
What is topographic maps?A topographic map depicts the geographical features of the region. They might make use of them to make sure their designs are on the proper road. It shows the elevation of a building site. Thus option D is correct.
Soil erosion is the process of flowing of soil with water during heavy rains or floods. Plant roots are strongly adhered and they strongly holds the soil under roots. They helps prevent erosion.
The term deposition means the laying down of sediments. Rock sediments sands, and other minerals undergo sedimentation.
Satellite views helps scientists the ability to predict catastrophic events. Satellites study changes occurring around planet and forecast the presence of extra terrestrial objects and their movements.

Ur suposed to solve for each one so like a you have to figure out what the speed is and b you have to figure out what the speed is and c you have to figure out what the speed is. Im pretty sure its the distance divided by the time to get the answers but im not sure.
Answer:
Explanation://
Answer:I think it is 50 m/s
Explanation:
Distance = rate * time
Divide both side by time to get rate
Rate = Distance / time
5/.1 = 50 m/s
10/.2 = 50 m/s
I have two questions
1. "Explain the relationship between amplitude and energy"
2."Explain the relationship between frequency and energy"
Answer:
1)The energy transported by a wave is directly proportional to the square of the amplitude. So whatever change occurs in the amplitude, the square of that effect impacts the energy. This means that a doubling of the amplitude results in a quadrupling of the energy
2)Just as wavelength and frequency are related to light, they are also related to energy. The shorter the wavelengths and higher the frequency corresponds with greater energy. So the longer the wavelengths and lower the frequency results in lower energy.
Explanation:
Gravitational potential energy is related to–A. what an object is made of. B.an object’s motion.C. an object’s position.D. an object’s color.
Answer:
The Answer is B because the material the object is made of, the position, or the color have absolutely nothing to do with gravitational potential energy

Lucia is playing with magnetic toy vehicles. She has two identical toy vehicles (purple and pink) that start on opposite sides of a center magnet that cannot move. She moves both vehicles one space closer to the center magnet.??? what
Answer: The potential energy of both toy vehicles (purple and pink) decreased. Since the pink toy was moved closer to the magnet, it will have less potential energy because of the short distance it will take to travel to the magnet.
Explanation:
Brainliest
Answer:
The potential energy of the two vehicles increased because they were moved against the magnetic forces. The potential energy of the pink car increased more then the potential energy of the purple car because the pink car was closer to the center magnet. Therefore the pink car been closer to the center magnet will experience a higher change in its potential energy than the purple car.

Jax fell while running and cut his knee. He noticed at the end of the day that his body had produced a hard film over his scrape. After two weeks, his scrape was completely gone and new skin had formed where his scrape had been. Which bodily system was repaired in order to protect the soft body tissues below Jax's skin?
Answer:
INTEGUMENTARY
Explanation:
The integumentary system repaired his scrape in order to protect the soft body tissues below Jax's skin.
What is the integumentary system?The integumentary system can be described as the set of organs forming the outermost layer of the body. It contains the skin which acts as a physical barrier between the external environment and the internal environment to protect and maintain the body.
The integumentary system involves hair, scales, hooves, feathers, and nails. It may serve to maintain water balance, protect the deeper tissues, excrete wastes, and maintain body temperature, and is the attachment site for sensory receptors which notice pain, sensation, and temperature.
The skin can be defined as one of the largest organs of the body and about 12 to 15 % of total body weight and covers 1.5 to 2m² of surface area. The skin can be described as a composite organ, composed of at least two layers of tissue: the epidermis and the dermis.
