Discuss the accuracy of results obtanied. Identify possible sources of error.
Discuss the experimental results in relation to accepted principles; were these theories verified by the experiment?
Discuss results obtanined with respect to thestated purpose of the experiment.
Do you have any recommendations in the equipment or procedure?
1. Were your measured values of the period of oscillation approximately equal to the predicted values? What specific defects in the apparatus and/or procedure might have contributed to the percent difference?
2. Were your values of k = ΔF/Δs nearly equal for each interval? If you plotted a graph of F vs. s, were the data points nearly along a straight line? (If so, your spring could be said to obey Hooke's law.)
3. Suppose a 350 g mass were suspended from your spring and allowed to reach the equilibrium position. Then suppose that the mass were pulled down 3 cm further and released. What would be the resultant force on the mass at the moment of release?
4. What would be the instantaneous acceleration at the moment of release?
A wrecking ball (800 kg) swings from a crane in a circular path of radius 20 m. At the bottom of its swing, it moves with a speed of 10 m/s; Calculate the centripetal force that acts on the ball
Two long concentric cylindrical shells are both centered on a longwire. The long wire has a constant charge density λ = 340microcoulombs per meter. The smaller cylinder has a radius of 3.75centimeters and has a constant charge density that appears..
Coherent light with wavelength 601 passes through two very narrow slits, and interference pattern is observed on a screen a distance of 3.00 from the slits.
A methane bubble 1.00 cm in diameter is released from the bottom of a lake 5.00 m deep. The temperature at the bottom of the lake is 4 °C. How many methane molecules are in the bubble
A high-energy pulsed laser emits a 1.0-ns-longpulse of average power 1.7×1011W . The beam is nearly a cylinder 2.5×10?3m in radius and it travels in free space. Determine the energy delivered in each pulse.
At what height above the earth is the acceleration due to gravity 45% of its value at the surface, What is the speed of a satellite orbiting at that height
Suppose a block with a mass of 3.25 kg is resting on a ramp. If the coe!cient of static friction between the block and ramp is 0.250, what maximum angle can the ramp make with the horizontal before the block starts to slip down
A simple pendulum makes 139 complete oscillations in 3.10 min at a location where g = 9.80 m/s2. Find the length of the pendulum
Light is incident normally on the largest face of an isosceles-right-triangle prism. What is the speed of light in this prism
An unstable particle at rest breaks up into two fragments of unequal mass. The mass of the lighter fragment is 2.70*10-28 kg and that of the heavier fragment is 1.65*10-27 kg. If the lighter fragment has a speed of 0.893c after the breakup, what is t..
A meteoroid is speeding through the atmosphere, traveling east at 21.5 km/s while descending at 19.0 km/s. What is its speed, in km/s.
