(See figure 1.1.) Figure 1.1 3) Use the masking tape to keep the cone closed. At the closed end of the cone (the bottom), use extra masking tape to cushion the blow from the fall AND weight the bottom. This will insure that the cone falls bottom side first. 4) Next, we will construct a box that is a little larger than the egg with the remaining poster board.
Cut the adhesive-backed foam weather stripping into one-inch pieces. 5. Cut the foam rope into one-inch pieces. 6. Glue the bottoms of the petri dishes onto the PVC tubes.
Gravlax Ingredients * 1 lump of salmon cut into two equally sized pieces. * Mix together 1 cup of kosher sea salt, 1 cup of sugar, a splash of vodka, and the zest of ½ a lime. * A large bunch of dill. Method 1. Spread out a piece of cling film about 5 times the size of one of the pieces of salmon until flat.

Jessica Yan Rick St. Denis, Tyler Wiseman 13 September 2012 Projectile Motion: Ball in the Bin Purpose: The purpose of the experiment is to determine the velocity of a ball launched from the Projectile Launcher device, and then to use that velocity to find where on the floor the ball will land given a specific angle. Theory: Two-dimensional motion is as it sounds, made of the two components of Vertical velocity and Horizontal Velocity. Horizontal Motion can be described as constant, neglecting air resistance, and Vertical Motion is characterized by the acceleration of gravity pulling at 9.8m/s². In this particular experiment, the total velocity will be split into the two components in order to find the time in the air, and horizontal distance from the launcher. The motion of these components can be described as d=vt for constant horizontal motion, and d=1/2at² + Vit.
A small round piece of zinc sinks when thrown in a pond and a substance like mineral oil floats on water (remember the test for iodine). But if that is true then why does a zinc-plated ship float on water? A zinc-plated ship floats on water because of its shape. If the body of the ship (hull) is designed perfectly then it can compensates for its own mass by displacing a sufficient amount of the mass of water. It has to displace enough mass of water before it sinks.
If the jacket slitting cord is present, separate it from the conductors and trim the back to the edge of the jacket. Untwist the inner conductor pairs and spread them apart so you can see each individual conductor. Line up the individual conductors so that the color code matches the color-coding standard you are using. Trim the conductors so that the ends are even with each other, making sure that the jacket of the cable will be inside the connector. The total length of exposed connectors after trimming should be no longer than 0.5" to 0.625".
How high was the copter when the package hit? Honors Supplement 1. If, from a height of 62m, Galileo accidentally dropped one of the cannon balls 0.5sec before the other, with what velocity would the second ball I have to be thrown downward to reach the ground at the same time as the first ball? [-5.3 m/s] 2. A flowerpot is dropped and passes by a window below.
Steps: A- The marble is dropped down the ramp (book). B- The marble rolls through the track of popsicle sticks at constant velocity C- The marble hits the ball of yarn causing it to stop while the ball of yarn rolls down the ruler. D- The ball of yarn falls into the bucket causing the string held by the book to be released and causing the bucket to fall down onto the switch of the fan. E- The fan then blows the golf ball down the track. F- The golf ball hits the clip holding the money case open causing it to shut G- Your money is now safe!
Procedure 3: The Compound Pendulum The aim of this experiment is to determine the value of the acceleration due to gravity by measuring the period of oscillation of the pendulum when suspended from different distances from its centre of mass. A pendulum consisting of any swinging rigid body which is free to rotate about a fixed horizontal axis is called a compound pendulum. This experiment had to be carried out at Glasgow University as the required equipment was not available at school. Procedure 1) The pendulum was balanced on a large brass knife edge to determine the position of the centre of mass of the pendulum. 2) The larger moveable knife edge was then clamped to the pendulum, at a small distance (1cm) above the centre of mass.
