Slav-nsk [51]
The correct answers are A, B, and C

- For example, hydrogen and oxygen are two elements that form to create water. Water is more complex than a simple atom of hydrogen or one of oxygen.

- Decomposition is an example of B

- Burning is an example of C.

D is not right because a chemical change can only join atoms or rearrange them, not completely change them.

Look at the images of Mars below. choose three features from the images and explain why they provide evidence thatt there is or
asambeis [7]

Answer:

Spot (4)  Has evidence that there were waves here at some point. It looks as if the sand/surface debris was moved back and forth, creating this pattern in the sand. Spots (5) and (7) show evidence of water erosion. The smooth edges of both hills mean that water once flowed through that area, carrying little pebbles and rocks that gradually shaped and smoothed those mounds. An example for this would be how there are smooth areas in the Grand Canyon where scientists have concluded that some, if not all, of the Grand Canyon was formed by flowing water. "Rapid uplift, cracking, and surface drainage of receding floodwaters provide both the path and the necessary volume of water to quickly carve out Grand Canyon," says scholars on icr.org.

Explanation:

Water Erosion exists.

blagie [28]

Answer:

Brainliest pls

Explanation:

Although the information for the trial was not given, we can offer a summed-up reply in that while playing out an analysis to accomplish outright zero temperatures, the worth won't ever match the specific worth.

What is absolute zero?

Absolute zero is the lower furthest reaches of temperature. Considered the coldest conceivable temperature that can exist. Nonetheless, any endeavor to arrive at this temperature in a controlled climate has fizzled, researchers don't think reproducing this temperature is conceivable.

In this way, we can affirm that the worth of indisputably the zero tests didn't match the acknowledged worth. Assuming the speculation was that it would be troublesome or difficult to accomplish, then the information would uphold the theory, if not, it would neglect to do as such.

In outline, outright zero is a temperature that can't be reproduced in a lab, so the worth in this analysis doesn't match the acknowledged worth and there could be no further investigation to be done on this.

Identify which best describes the energy used to pluck guitar strings to make sound. A) electrity b) electromagnetic c) heat d)
DochEvi [55]

The capability to do work is said to be energy. It can neither be created nor be destroyed according to law of conservation of energy. Energy exist in different forms depends upon the work to be done such as potential energy, kinetic energy, mechanical energy, heat energy etc.

Now, when the guitarist plucks the guitar strings to make sound, he uses mechanical energy and when guitarist plucks the guitar strings guitar produces sound energy also.

Thus, option (d) is the correct answer.
