which of the following is a term for the process of rock being broken down into pieces by wind or moving water?
A: Deposition
B: Compaction
C: Weathering
D: Cementation
Electric Charge (guided inquiry)
Purpose: To show how matter becomes charged by induction
Materials: comb, sink with working faucet
Predict: Predict what you think will happen to the charges of the comb and water if the comb comes in contact with the water. Record your hypothesis before following the directions below to carry out the lab experiment. The charges would attract. How and why is what I don’t know.
Directions:
1. Turn on a faucet just enough to allow a thin stream of water to flow.
2. Have a student volunteer-run a comb through his/ her hair a few times.
3. Observe. Tell the student to hold the comb near, but not touching, the stream of water.
4. Answer all questions below in complete sentences, using the R.A.C.E. strategy.
Ask and record your findings: What do you observe? Describe. I observed the stream of water bend toward the comb. I gave the comb electric charge by passing a comb through my sister’s hair and that allowed the comb to bend the stream of water.
Ask and record your findings: What does this indicate (show)? Explain. I
Written response please read all and answer in complete sentences will give BRAINLIEST
Observe:
1. To test students’ predictions, have the student volunteer pass the comb through the water.
2. Then have them move the comb so that it is near but not touching the water.

Explanation:
Samuel throws a ball into the air 20 meters. It reaches the top of its flight at 2
seconds and hits the ground at 4 seconds. What was the ball's average speed on the
way down?
Answer:
10 m/s
Explanation:
The ball's average speed on the way down is 10 m/s.
How fast does the ball travel when dropped?It would be pretty easy to find the speed of any falling object because they all speed up at the same rate – 3.6 mph every second.
How do you find the average speed of a ball?Average speed can be calculated using the formula v=d/t where the variables are:
1 v is the average speed of the object with units of m/s.
2 d is the total distance or length of the path of the object with units of m.
3 t is the total time taken to cover the path with units of s.
4 Speed cannot have a negative value.

Please please answer this! explain the kinetic molecular theory ( i don't understand how they explain it in my lesson so if someone could simpfly it for me) worth 30 points
Answer:
Explanation:
Basically, Kinetic Molecular Theory says that gas particles are in constant motion and that they show perfectly elastic collisions.
An elastic collision is a collision in which there is no net loss in kinetic energy in the system as a result of the collision.
So the kinetic molecular theory says that gas particles stay moving constantly and don't lose energy when they run into each other.
Hope this helps!
