The Blue Machinery of Summer – Yusef Komunyakaa The central conflict is that he does not feel the same since he has come back from Vietnam. I would say there are two instances that he best describes this problem. "I still hadn’t told her I felt I’d left part of myself in her country." (88) Another moment was at the very end when he imagines the faces of the dead from Vietnam on his way to L.A. I think that the whole story builds up suspense by the way he dances around the problem and never talks

Cork Rocket Target Grade: Hopefully 10 to 14 year olds Objectives: To show student how chemical reactions can react with one another to create totally new compounds. Liquids and solids can combine to create gasses with practical and fun applications. Materials: A litre-bottle‚ Cork (if cork doesn’t fit into bottle‚ either cut it‚ or place paper towels around it so it will fit snugly into neck of bottle)‚ Paper Towels‚ Streamers (or anything light and dangly‚ paper is okay if it is in

Motion NCERT Chapter Questions and Answers and other Q & A Q1: An object has moved through a distance. Can it have zero displacement? If yes‚ support your answer with an example. Answer: Yes an object can have zero displacement even though it has moved through a distance. It happens when the object moves back to its original position i.e. final position coincides with the starting position. Example: Suppose an object travels from O to C and then comes back to original position O. Total

of vinegar‚ will cause a film canister rocket to shoot the furthest. I think 5mL will shoot the farthest because there will be more for the baking soda build up in the canister. The independent variable is the amount of baking soda. The dependent variable is how far the rocket launches.

started off with a bottle rocket project. This project lead us to become more educated with Newton’s laws of motion. The bottle rockets also lead you to learn about mass‚ force‚ and acceleration. As you know the first law of motion is that if objects at rest will stay at rest‚ or objects in motion will stay in motion‚ unless acted upon by an unbalanced force. Well in order for the rocket to lift off it will need force applied to it. It is required to add water for your rocket and you don’t want to add

Rocket Propelled Grenades It was early morning the sun was peeking over the horizon. The military helicopter was cruising at about 200 feet air to ground level‚ departing a river valley base in Afghanistan. Everything seemed routine until a loud bang occurred and the helicopter yawed to the right. As the crew chief looked back‚ there was a huge hole on the left sponson with the sun rays making its was into the cabin. With a quick assessment from pilots and crew‚ the conclusion was made

A rocket in its simplest form is a chamber enclosing a gas under pressure. A small opening at one end of the chamber allows the gas to escape‚ and in doing so provides a thrust that propels the rocket in the opposite direction. Newton’s laws can be used to explain this his laws in the simplest terms can be explained like this: First law- Objects at rest will stay at rest and objects in motion will stay in motion in a straight line unless acted upon by an unbalanced force. Second law- Force

Inertia can best be described as _____. a. the force which keeps moving objects moving an stationary objects at rest. b. the willingness of an object to eventually lose its motion c. the force which causes all objects to stop d. the tendency of any object to resist change and keep doing whatever its doing 7.

Propelling a Rocket with Baking Soda and Vinegar Materials: * Vinegar * Baking Soda * Paper Towel * Funnel * Cork * In rocket: (instead of film canister) * Plastic Bottle * Pencils(stand) * Duct tape Procedures: 1. Take 1 scoop of baking soda 2. Put it in the middle of the paper towel‚ and then roll it. 3. Put the funnel in the mouth of the bottle‚ and pour vinegar before the duct tape.(it’s up to you) 4. Fix the cork‚ put some paper

Motion and Change Motion and Change two physical displacement features that in turn make up all the physical reality. The rotational motion of electrons and nucleus generate the electrical fields that create all the elements known to man. The amount of neutrons and electrons depends on the elements structure‚ for example water is H2O. Water requires one hydrogen atom and two oxygen atoms this mixture combine creates water.
