Compared to a ball thrown at 10 meters per second, which statement describes the change in kinetic energy of a ball of the same mass thrown at 20 meters per second?
1) The kinetic energy of the ball thrown at 20 meters per second is half (½×) the kinetic energy of the ball thrown at 10 meters per second.
2) The kinetic energy of the ball thrown at 20 meters per second is two times (2×) the kinetic energy of the ball thrown at 10 meters per second.
3) The kinetic energy of the ball thrown at 20 meters per second is the same as (=) the kinetic energy of the ball thrown at 10 meters per second.
4) The kinetic energy of the ball thrown at 20 meters per second is four times (4×) the kinetic energy of the ball thrown at 10 meters per second.

Rock, Paper, Scissors
In this unit, you expanded your Python skills, and now you can really have some fun! In this lab, you are going to create a game that allows the user to play Rock, Paper, Scissors against the computer. If you aren’t familiar with this classic game, here’s how it works: two people (or a person and a computer!) each select either rock, paper, or scissors. The player who chooses the stronger object wins. Here is how the winner is determined:
Rock beats scissors because a rock can break scissors.
Paper beats rock because paper can cover a rock.
Scissors beats paper because scissors can cut paper.
Go to https://repl.it/ to write your program.
Your program should do the following:
Randomly choose rock, paper, or scissors for the computer
Ask the user to choose rock, paper, or scissors
Compare the computer’s choice to the player’s choice
Announce whether the computer or the human won
Here are two hints to help you write this program:
Test parts of your program to see if they work before moving on to work on other parts. For example, you will need to have the computer select a random number and then choose for that number to correspond to rock, paper, or scissors. You can write just that portion of the program and then test it by having the program print the word “rock,” “paper,” or “scissors” before you even begin working on the part of the program where the user inputs their choice. (Of course, don’t forget to erase the line of code that prints the computer’s choice when you are finished testing—otherwise the game will be just a bit too easy for the user!)
On a piece of paper, draw a chart that shows all nine possible outcomes of the game and use that chart to design and test the program. The chart might look like this:
TABLE 1 Rock paper scissors outcomes
Computer chooses rock Computer chooses paper Computer chooses scissors
User chooses rock
Tied game
Computer wins
User wins
User chooses paper
User chooses scissors
Run several tests on your program to be sure that the correct winner is announced.
When your program works properly, take a screenshot of your code to turn in.

Answers
Answer:
D. 4x as much
Explanation:
The answer is pretty simple. The question is asking about 10m/s and 20m/s right? Take a look at the energy at each point on the graph. At 10m/s the kinetic energy is 100 on the graph. At 20m/s the kinetic energy is 400. You'll notice that 100 x 4 is 400 - That's the answer.
You can also prove this mathematically. The formula for kinetic energy is
[tex]\frac{1}{2}mv^2[/tex]
The question says: constant mass so we can ignore that for now.
(1/2) * 10^2 is (1/2) * 100 = 50
for the 20m/s ball it would be
(1/2) * 20^2 = 400 * 1/2 = 200
Once again, you see that it is 4x
Answer:
It is weird that you put this the computer and tech. But it's (D. The kinetic energy of the ball thrown at 20 meters per second is the same as (=) the kinetic energy of the ball thrown at 10 meters per second. !!

The data from the electromagnet experiment suggest some relationships between a cause (the construction of the electromagnet) and an effect (the number of paperclips lifted).
Think about the differences between Magnets A, B, and C. Now, select a question that you could ask to help you understand how the construction of an electromagnet affects its strength.
1) What effect does increasing the number of wraps of wire have on the strength of the electromagnet?
2) Will the magnet pick up other objects?
3) Does the battery need to have energy left in it?
4) Why does the nail pick up paper clips?
