How long does it take to go from floor to ceiling'? 5. A second ball is bounced with the same velocity as the first. It leaves the floor at the instant the first ball leaves the ceiling. a.
5 .For part III, Average was needed to be found after Find the Mass/A of each all 5 disk. To do that Add all the values in Table 3 and divide them by 5. 6 .For Part III, Percent difference between the average value and the slope of the derivative diameter graph was found by doing this: ((slope of the derivative vs. diameter graph- average)/slope of derivative vs. diameter graph)*100 =67.9% VII. Analysis Questions/Answers 1. The Slope in Part I represents π 2.
The relationship between Hamstring strength index 60 degree/s and the Shuttle run test is a negative relationship due to r moves away from zero in negative direction and r = −0.149, the strength of this negative relationships would be weak with r -0.5 r=-0.528**, is more significant since p =0.002< 0.01, where r = −0.498** is significant at p =0.004< 0.01. The smaller the p-value in a test of hypothesis the more significant the results are. 8. The researchers stated that the study showed a positive, significant correlation between Quadriceps strength indices and pre- and postoperative functional stability Considering the data presented in the Table 5, do you agree with their statement? Provide a rationale for your answer.
What do you suppose the x- and y-coordinates will be for that circle in Quadrant I? - The coordinates for quadrant I would be (5,0). This is if you take a basic unit circle with a radius of 1 the coordinates for quadrant I would be (1,0) therefore if you have a circle with a radius of 5 the coordinate values would be (5,0) because the circle only expanded in size. 5.Consider the two points in Quadrant I on Circle B. What is the special relationship between them?
6. Which of the following sets of variables has the strongest relationship? a. Hamstring strength index 120°/s and the Hop index b. Quadriceps strength index 60°/s and the Carioca test c. Quadriceps strength index 120°/s and the Side step test d. Quadriceps strength index 60°/s and the Triple hop index The answer is D. because r=0.619, which is closest to +1.00 than all the other answers. 7. In Table 5, two r values are reported as r = −0.498 and r = −0.528.
For this problem, note that "Target" = .75, and "Actual mean" = .753. 4) What is the probability that a ball bearing will be between the target and the actual mean? P(.75≤x≤.753)= .273373 5) What is the probability that a ball bearing will be between the lower specification limit and the target? P(.74≤x≤.75)= .22605 6) What is the probability that a ball bearing will be above the upper specification limit?
Cowan 1 Merrily We Roll Along Lab Report In this lab we were investigating the relationship between distance and time for a ball rolling to and inclined plane. How will the distance and time be related for a ball rolling down an inclined plane? If the angle of the incline is greater, then the rate of acceleration of the ball will also be greater because it will be rolling down at a steeper incline. This predicted hypothesis is testable with an experiment. The materials needed for this experiment will be a ball, a meter long ramp, tape, a protractor, and stopwatch.
This location varies on all bats, but it is generally considered to be about 5 to 7 inches from the end of the barrel. When the bat meets the baseball the collision causes the bat to vibrate. And hitting a baseball on the wrong part of the bat can cause vibrations that are extremely painful (I have experience with this! ), especially on a cold day. If you hit the ball at the sweet spot, the bat doesn’t vibrate (this gives more encouragement to hit the sweet spot if you ask me).
Q = Mc Cc ΔT (2) Where Cc = 0.215 cal/(g °C) A nylon cord is wound five times around the aluminum calorimeter. The frictional force between the band and the calorimeter is large enough that one end of the band can lift a 10 kg weight while the other end becomes slack. As a result of this mechanical trick, the frictional force is equal to the weight of the 10 kg mass and is to a large extent independent of the speed at which the drum is rotated. The work of friction (Wf) is
Because we rotate the turn table. So the ball does not take the direction that should take (straight line) but it deflects. 5. Did the ball actually curve as it rolled across the turntable? Yes the ball actually curve due to deflection.
