Then Kaku states that force fields can do more than deflecting laser beams because it can levitate objects by the use of magnetic force fields. To support that, he explains that when we place two magnets opposite to each other, the two magnets will repel each other. However he wrote that making force fields and to levitate heavy objects is nearly impossible since we lack advanced technology. For my response, Kaku doesn’t completely explain everything. Suppose that you have a structure on a planet or a spaceship in the middle of nowhere, and suppose you don't want the force field on all the time either because there are times when protection isn't needed.
Following the Daily Roll Call its time to gather all required equipment for Officers Don’s patrol shift. Equipment consist of a bag that has water, traffic vest, recorders, PBT, and keys to the city. With the quick grab of the taser officer Don is ready to head to the patrol car. Inside the patrol car you will find extra equipment including flares, radar detector, shot gun, laptop, and all the tickets are conveniently printed in the head
Cunningham I.S 234 Natalie Massry Class 832 May 22 , 2013 Science Project Definition of Collision Particles first have to collide, and only the collisions that have sufficient energy will cause a reaction. For a successful collision to occur the particles must have sufficient energy to pass the activation level. Things that alter reaction rate: Temperature: particles move faster when they have more energy, by moving faster you increase the chance that there will be a collision,
Reaction rate is affected by any catalysts present (which speed up the reaction usually with an intermediate step), temperature (increases the number of particles collisions), concentration (increases the number of collisions), and surface area (increases the space available for collisions). Reactions can only occur when collisions take place. The most generic form of the rate law is Rate = K * [A]m * [B]n where (k is a constant specific to an equation and temperature). Now, the compounds A and B might not have any effect on the rate, which would cause them to drop out of the equation completely, or they might have so much effect that they are raised an order (squaring the concentration). The rate law for this reaction is k [CV+]m[OH-]n. Since the hydroxide ion concentration at the beginning is about 1000 times larger than the concentration of crystal violet, [OH-] will not change that much during this
In practice we observe real collisions because there is always some loss of kinetic energy in the form of sound, friction etc. during such collisions. Dropping a ball made of a certain material on a given surface of known material from a given height is one of the simplest ways of determining the COR of the ball–surface material combination. In laymen's terms, the coefficient of restitution is a measure of bounciness. Measurement of the COR for a collision between a ball and a flat surface by comparing the height of rebound after impact/collision has been of
Use the postulates of the kinetic theory to explain the following: i)Matter can exist in three states ii)The pressure exerted by a confined gas decreases as its temperature is lowered iii)A gas of low molecular mass will diffuse through air faster than a gas of high molecular masseven though both are at same temperature. The Kinetic Theory can be used to describe the three physical states of matter namely, solid, liquid and gas. In this theory, some basic assumptions has to be made: a) all matter is made up of extremely small particles b) these particles are in constant random motion c) all collisions between these particles are elastic, and d) mutual attractive forces exist between particles The explanation below gives more information about the three states of matter: i) solids > particles are held together in a regular pattern by strong attractive forces. > particles vibrate about in fixed positions. ii) liquids > vibrating particles have sufficient energy to move from their fixed positions to other parts within a liquid.
If the sample was to re-colloid, it would easily wash right through the filter, causing the analytical results to be low. Once the precipitate is dried, the silver and chlorine can be separated by simply being in the presence of light, illustrated in the below equation: AgCl(s) → Ag(s) + 1/2Cl2(g) This decomposition happens quite quickly in strong light; however, it mostly occurs on the surface of the precipitate because its opaqueness protects all the material below the surface. If there are excess silver ions during the decomposition, another reaction may occur: 3Cl2(g) + 3H2O(l) + 5Ag+(aq) → 5AgCl(s) + ClO3-(aq) + 6H+(aq) In this reaction, some of the chloride
Physics Lab Report Lab 3: Energy and Momentum Group and name Abstract: In our experiment, we were trying to find the energy loss due to semi elastic collision and friction. Also we found the efficiency of the collision using certain equations. We found out that the loss of energy due to semi elastic collision is a lot more than the loss of friction. We had many external errors with measuring because of our inaccurate source of measuring system. The materials we used were 6 steel ball bearings, a U-track, meter stick, and triple beam balance.
Energy may also be stored (potential energy). If any work is done, some starting energy is lost as heat. This includes energy transfer at a cellular level. Therefore, this is not 100% efficient method and, unless the system is continuously topped up with energy input, it will break down. The second law of energy states that all natural processes tend to proceed in a direction which increases the randomness or disorder of the system.
This causes the rubber band to have an elastic limit which is caused when the molecules’ motion is stopped by these cross links. The disorder in the rubber band is described as its entropy, so when there is a high level of disorder of the molecules, there will be a high entropy level. When stretching occurs, the molecules line up and they uncoil from their original structures. This causes the molecules to become more ordered and so lowers the entropy. Heat is then given out when entropy decreases and therefore energy is lost.
