Graham’s number‚ named after Ronald Graham‚ is a large number that is an upper bound on the solution to a certain problem in Ramsey theory. The number gained a degree of popular attention when Martin Gardner described it in the "Mathematical Games" section of Scientific American in November 1977‚ writing that‚ "In an unpublished proof‚ Graham has recently established ... a bound so vast that it holds the record for the largest number ever used in a serious mathematical proof."

Experiment 9: Maxwell’s Wheel Introduction: The second lab performed on 2/1/12 involved two investigations concerning Maxwell’s wheel. Maxwell’s wheel is an apparatus that consists of a large disk with a long axle. The disk then bound to a support hanging from above with strings attached to each end of the axle. Maxwell’s wheel is considered to be an important apparatus to investigate physical phenomenon’s because it its ability to combine straight line motion and rotation of a rigid body

object is moving with uniform accleration. Its velocity after 5 sec is 25m/s and after 8 sec‚it is 34 m/s. Find the distance travelled by this object in 12th second. Ans. 44.5 A particle starts with a velocity of 100 cm/s and moves with –2 cm/s2 acceleration. When its velocity be zero and how far will it have gone? Ans. 50s ‚ 25m m/s. After 7 a time interval ∆t‚ the velocity of the body is reduced by half‚ and after the same time interval‚ the velocity is again reduced by half. Determine the velocity

(a) Positively accelerated (c) Uniform accelerated (b) Negative accelerated (d) None of the above [1] 2. What does slope of position time graph give? (a) speed (b) acceleration (c) uniform speed [1] (d) Both (a) and (c) depending upon the type of graph. 3. When a body moves uniformly along the circle‚ then:(a) its velocity changes but speed remains the same (b) its

graph of 2 x distance vs. time squared represents acceleration. It represents acceleration‚ because the line shows that the graph is steadily increasing‚ because of its almost constant slope. As a result‚ the slope of the line is constant‚ and so the acceleration is constant. Additionally‚ to determine an experimental value for acceleration one must find velocity‚ time‚ and then calculate your equation. Then‚ calculate gravity by using the acceleration value and divide it by 0.0043. g=
