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?

Answers

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.

1. How does the structure of a hard-boiled egg compare to the crust, mantle, and core structure of Earth? What do the egg's layers represent? What might the cracks represent?

2. How do Earth's layers compare in composition and properties with the egg's layers?

3. Can an egg be used as a satisfactory model for Earth's lithosphere (plates) and asthenosphere, plus the rest of the mantle, and the core? How? (Hint: Look very carefully under the shell could the membrane there represent the asthenosphere?)

4. Overall, is the cracked egg a useful model for Earth? Why or why not?

5. Unlike the eggshell sections, Earth's plates move relative to one another. A plate may move away from another plate, or it may move toward it. Earthquakes often result from interactions between plates. Predict what other consequences might result from plate motion.


6. Of the several possible non-egg models of Earth, which do you feel is most appropriate? Why?

2. Earth layers compare in egg layer it is hard on the outside

Explanation:

Answer: for 1 and 2 The inside of the earth is layered something like an egg. Both have a thin, brittle shell. The crust of the earth is broken into pieces, like the cracked shell of a hard boiled egg. The mantle of the earth is like the egg white, and the core of the earth lies in the center, like the egg yolk.

for 3 the shell could also be used because you can crack

for 5 a few things that can happen in the result of plate motion there could be Mt formation or volcano formations.

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

Answers

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.
