Particles pass through a single slit of width 2.0 mm (see Figure 29.15). The de Broglie wavelength of each particle is 490 nm. After the particles pass through the slit, they spread out over a range of angles. Assume that the uncertainty in the position of the particles is one-half the width of the slit, and use the Heisenberg uncertainty principle to determine the minimum range of angles.
A bicycle wheel has a diameter of 64.1 cm and a mass of 1.81 kg. suppose that the wheel is a hoop with all of the mass concentrated on the outside radius. The bicycle is placed on a stationary stand and a resistive force of 120 N is applied tangent..
A screen is placed 42.7 cm from a single slit that is illuminated with light of wavelength 677 nm. If the distance between the first and third minima in the diffraction pattern is 3.45 mm, what is the width of the slit.
If the dummy is thrown forward with force of 130.0 N while simultaneously being hit from the side with a force of 4500.0 N, illustrate what force will the sensor report?
An electron in an oscilloscope is accelerated as a result of the potential difference between the cathode and anode. The electron has negligible initial speed and a final speed of 2.40 107 m/s. Find the voltage drop from cathode to anode.
Two 1.90-cm-diameter disks spaced 2.10mmapart form a parallel-plate capacitor. The electric field between the disks is 5.10×105V/m, What was the electron's speed as it left the negative plate
Water flows over a section of Niagara Falls at the rate of 1.1 x10^6 kg/s and falls 55 m. How much power is generated by the falling water.
Two long parallel wires each with a mass per unit length of 25.10 g/m are supported in a horizontal plane by 2.5 cm long strings. Each wire carries the same current, I, causing the wires to repel each other so that the angle between supporting string..
A uniform electric field points midway between the positive x and y axies. Its strength is 100Volts/m. A -50nC charge is placed at the position ( 2m, 3m ) and fixed in place. What are the components of the total electric field at the location (..
What is the cannonball's velocity at the highest point in the trajectory, How long does it take to get to this point
A meterstick is at rest in an inertial frame S2. If S2 moves with a speed of 0.7c with respect to a rest frame S1, find the length of the meterstick as measured in frame S1 according to classical physics. Reply in units of m.
At the same time, car 2 is 1.2 east of mile marker 0 travelling at 30 due wests. Car 1 is speeding up with an acceleration of magnitude 0.20, and car 2 is slowing down with an acceleration of magnitude 0.60.
What percentage of the neutrons would not interact if the concrete slab were made 36.0 cm thick? I know this is 1.305x10^1. B) How many centimeters thick would the concrete need to be so that 18.0 per cent of the neutrons are transmitted?
