Which statement summarizes the theory of plate tectonics?
A.
Only the continents move, traveling slowly over and through Earth’s crust.
B.
All of the continents were once joined together into a single supercontinent.
C.
The continents are fixed and have always been located in their present positions.
D.
Earth’s crust is made of pieces that move slowly over, against, and apart from each other.
Answer:
D
Reason is because tectonic plates do these three things on a daily basis.
But B us also correct if you look at the history aspect of it.

A student observes interactions between two sets of electrically charged objects. In each set, the objects carry either a charge of -1 or +1 Coulomb. Which question can the student ask to identify the set with the stronger interaction?
Answer:
He can ask which set will have the least mass and most acceleration.
Explanation:
Because F = m x a is true and we have the highest acceleration between the sets which means we do have the highest force and because gravity is playing a big role in that process we could say the objects force is mass divided by gravity times the acceleration equals the force unless if there was 0 gravity we would have the original formula. In conclusion, he should ask the question of which set will have the least mass and most acceleration.
after acceleration the iron nuclei travel at a steady speed of one-tenth of the speed of light .the speed of light is 3.00 x 10^8. calculate the time taken for the iron nuclei to travel at a distance of 12000m

Clara and Eli used materials they could find at home to make a simple seismograph. As Clara pulls the strip of paper through the seismograph, Eli gently shakes the table.
Make a prediction. What will happen to the paper as Eli shakes the table?
Answer:
Would you be so kind to change a few words or sentence structure when you're submitting? This is the answer I wrote and what I'll submit. And I really don't want the teacher to think that I copied off of someone.
Explanation:
As they shake the table a seismogram is being made, which is a recording of those "ground shakes" created by students. Eli shakes the tables up to down creating movement, which is being recorded by a fixated pen inside a machine as Clara pulls a strip of paper through the seismograph.

A student conducts an investigation to show the relationship between temperature and kinetic energy in one phase of matter. What would the graph of this relationship look like?
Answer:
exponential growth
Explanation:
they will rise
The relationship between temperature and kinetic energy in one phase of matter is exponential.
What is kinetic energy?The energy an object has as a result of motion is known as kinetic energy. A force must be applied to an object in order to accelerate it. We must put in effort in order to apply a force. Following work, energy is transmitted to the item, which causes it to move at a new, constant speed.
Each molecule in a group has a kinetic energy that may be determined using the equation above. A group of molecules will have a wide range of kinetic energy, from very low to extremely high, even though they all have constant masses due to differences in their velocities. The general distribution will not vary, even though the kinetic energy of each molecule may fluctuate frequently.
The relationship between temperature and kinetic energy in one phase of matter is exponential.

Imagine that there is a small rocky body caught by Earth’s gravity. Draw a comic-strip cartoon to illustrate its journey as it travels through space toward Earth, enters Earth’s atmosphere, and lands on Earth. Describe your illustration with narration or speech/thought bubbles. Include the use of these key terms: atmosphere, meteor, meteoroid, meteorite.
To create this comic strip you can use a narration describing each step and illustrate each one with one image or drawing.Creating a comic strip involves using images and short texts to explain a specific idea or phenomenon. In the case of the process for a meteor to enter Earth you can use the following ideas.A meteoroid approaches the Earth at high speed and draw a meteor traveling near to different planets and approaching Earth.What is that? and draw the Earth wondering who or what is approaching.The meteoroid enters the atmosphere of the Earth and becomes a meteor and draw the rocky body burningThe rocky body crashes with the surface becoming a meteorite and draw the zone where the meteorite crashed.

Sue used data on an active volcano to demonstrate two different types of eruptions on the sun. She wrote the following observations about an active volcano.
The volcano continuously spews a slow stream of hot gases.
It erupts violently after gaps of several years and spews very hot gases.
Which statement is correct about the eruptions on the sun represented by Sue's observations?
Observation 1 represents a solar wind because solar winds are a continuous stream of particles given off by the sun.
Observation 1 represents a CME because a CME is a cloud of plasma which bursts out of the sun's atmosphere.
Observation 2 represents a solar wind because the solar wind travels at a very high speed in a specific direction.
Observation 2 represents a CME because a CME is a magnetic storm on the sun which produces high energy particles.
Regarding the solar eruptions that Sue's observations depict, statement D is accurate. Because a CME is a magnetic storm on the sun that generates high-energy particles, observation 2 depicts a CME.
What is an eruption of the sun?Sunspots are solar eruptions that happen when magnetic lines twist and abruptly realign close to the sun's surface.
Coronal mass ejections (CMEs), or streams of charged particles that launch into space, are occasionally linked to these events.
Hot gases are continually released from the volcano in a steady stream. After a few-year hiatus, it bursts suddenly and emits extremely hot gases.
The assertion that Sue's observations depict eruptions on the solar is true, observation 2 does represent a CME since a CME is a magnetic storm on the sun that generates high-energy particles.
Hence, statement D is accurate.

the gravitational energy of a golf ball at differnt heights is shown in the table below which graph best represent the relationship between the ball's gravitational energy and its height above the ground. I need helplease. See answers. Advertisement. yeabsiraerstu. Answer: A because it's uniform. Its right on a-p-e-x thanks. Advertisement. Nind10.
Explanation:
The graph that would best represent the relationship between the ball's gravitational energy and its height above the ground is a straight line graph.The straight line graph would start from zero and increase linearly as the height of the ball above the ground increases.
The graph that best represents the relationship between the ball's gravitational energy and its height above the ground is a straight line graph. The energy of a golf ball at different heights is directly proportional to the height of the ball above the ground.
Therefore, the graph that would best represent the relationship between the ball's gravitational energy and its height above the ground is a straight line graph.The straight line graph would start from zero and increase linearly as the height of the ball above the ground increases.
The straight line would have a positive slope, and the steeper the slope, the greater the rate at which the energy increases with height. Therefore, the straight line graph that represents the relationship between the ball's gravitational energy and its height above the ground would be a straight line with a positive slope.
The graph would show the gravitational energy on the y-axis, and the height of the ball above the ground on the x-axis. The graph would show the increase in gravitational energy with an increase in height above the ground, and it would show a straight line graph with a positive slope that represents this relationship between the ball's gravitational energy and its height above the ground.
