3d photo

 To make this 3D picture, I first took two pictures of the ipod. One in the center of the object, then a little to the left for the second one. I then imported both photos in Photoshop on the computer. I then put a red blue filter on the pictures and then put one piicture over the other, which gives it the 3D effect.
 The reason why the 3-D effect works is becasue the glasses have a green and yellow fileter on it so that the colors pop out and the effect work when you look at the picture.
In order for the viewer to see the 3D photo, they have to look at the picture with the 3D glasses.

Dancing and Sticking Salt mystery

Why does the salt bounce off the conducter but stick to the insulator?

The salt bounces off the conducter because the conducter is positivley charged like the salt is. the insulator however is not, it is negativley charged instead.

to prove this the process we took to was to first rub the fur to the pipe making the pipe negativley charged. then take it near the salt and observe the following results. which are showed in the picture above.

Frequency = 27 HzLength= 2.87 Meters
2 waves

For the Wavelength of a single wave take the length and divde it by the number of waves.
2.87/2 =1.435 Meters per wave.

To find the Speed Multiply the Wavelength by the Frequency
1.435 x 27= 38.74 m/s

steel ball mystery. - Olivia and Kaleb

The ball on the right has greater velocity because as the ball on the left transfers its velocity to a magnet transfers the velocity to the next ball.  it to another pair of steel balls, in which the second steel ball of the pair shoots off with a greater velocity than the first steel ball, this continues until the very last ball gets velocity transferred to it, causing it to shoot off the greatest velocity out of all the steel balls. The magnet not only help transfer velocity of the steel ball to the next, it actually increases the velocity of the steel ball because one side of the magnet has a magnetic pull on one of the steel balls causing the other side of the magnet to repeal the other ball with more force because is absorbed the velocity of the first ball and expels it on the other side with more velocity causing it to speed towards the next magnet that pulls the steel ball towards it...etc. Until it reaches the last steel ball.

Steel Ball Mystery Project - Jacob Avorio, Christian Bobrowski

The right ball had a greater velocity than the left ball that was initially sent because the bounces made by every collision increased the following impacts. The last marble to be hit took the most damage and had the most momentum. It would happen on a Newton’s cradle because one ball whacks another and stops because they have equal mass (just like a billiard ball).

Mamma said, "Well, objects that are still don't move spontaneously, so they tend to stay at rest. When you flick the coin fast enough, the only coin that is effected is the one hit on the bottom. The slower you flick the coin, the more you disturb the other coins."

Whatever Mamma says goes, bub.

Christian Bobrowski, Extension 6, Questions

Question 1:

How does winning this game require you to apply Newton's 1st and 2nd laws?

Answer:

In the game vector racing, winning this game applies yopu to apply both of Newton's laws. The first law states that an object in motion will remain in motion unless acted upon another force, and same goes for if it is at rest. In this game, you have to pinpoint exactly where you want the car to go, just like an endpoint. The car will remain in motion until it reaches that final endpoint in which you set. Newton's second law states that when certain forces are unbalanced, objects will tend to accelerate. In the game, once you have clicked enter and chosen where you want the car to end up, you are unable to stop in the middle and change locations. It will constantly take the car to the spot you intended it to, until it reaches that end point. This is how the game vector racer requires the users to apply both Newton's first and second laws.

Question 2:

How do these principles apply to your own driving - especially in the winter?

Answer:

These principles also apply to my own driving in certain ways especially during the winter. This is because for instance if it is very icy and the roads are slippery, the car tends to not neccessarily stop at the given time. It makes it much much challenging for the car to come to a stop because it is a sliding road which is not the easiest to maneuver through. Not only that, but it is also harder to navigate the car through the snow, making it somewhat difficult depending where you are driving to accelerate as quickly as you normally would. This is why both of these principles can also apply to my own driving, espeically when it is the winter season.
