1. This question will ask you to determine the area of a flat piece of metal according to the data in the table below. The answer will need to be correctly state as mean value±?m units, for example Area = 3.2 ± 0.2 cm 2 . Length (cm) Width (cm) 8.4 6.3 8.6 5.9 8.3 6.2 8.7 6.5 8.5 6.3 8.8 6.1 a. (4 points) Determine the mean, standard deviation, and the standard deviation of the mean for the length measurements. Show all your work. Properly report the length and its error. b. (2 points) Determine the mean, standard deviation, and the standard deviation of the mean for the width measurements. Properly report the width and its error.(Hint: you can use scientific calculator or Excel to get results).
A student has two ramps, both of which are at an angle 32°. Ramp 1 is frictionless and ramp 2 has friction. The student also has two blocks, one for each ramp.
The plates of a parallel-plate capacitor in vacuum are 25 micrometer apart and 88 square cm in area, Calculate the charge on each plate, the capacitance and the energy density
One of the weapons considered for the "Star Wars" antimissile system is a laser that could destroy ballistic missiles. When a high-power laser is used in the Earth's atmosphere, the electric field can ionize the air, turning it into a conducting p..
An ideal gas is in contact with a heat reservoir to that it remains at a constant temperature of 300.0 K. How much heat flows between the gas and the heat reservoir
An 80 kg skydiver falls through air with a density of 1.15 kg/m3 . Assume that his drag coefficient is C=0.57. What are the terminal speeds in both cases
An object whose weight is 100 Ibf experiences a decrease in kinetic energy of 500 ft. Ibf and an increase in potential energy of 1600 ft. Ibf. The initial velocity and elevation of the object, each relative to surface of the earth, are 50 ft/s and 40..
A straight, nonconducting plastic wire 8.50 cm long carries a charge density of +175 nC/m distributed uniformly along its length, Find the magnitude and direction of the electric field
The current in the circuit if the speed v is 0.75 m/s , determine which end of the rod is positive.
A 100g wire is held under a tension of 250N with one end at x = 0 and other x = 10m. At time t = 0, pulse 1 is sent along the wire from the end at x = 10 m. At time t = 30 ms, pulse 2 is sent along the wire from the x = 0. At what position x do the..
