FIGURE 10-30 Problem 37
38. • The tires on a car have a radius of 31 cm. What is the angular
speed of these tires when the car is driven at 15 m/s?
39. A child pedals a tricycle, giving the driving wheel an angular
speed of w = 0.875 rev/s (FIGURE 10-31). If the radius of the wheel is
r3D 0.260 m, what is the child's linear speed, v?

- All of the high-energy physics colliders built in recent decades have collided one beam of particles with a second beam traveling in the opposite direction. For example, the Large Hadron Collider at CERN sends particles of opposite charges around a ring, with one beam traveling clockwise and the second traveling counterclockwise. Technically it is much more difficult to get the two beams to collide with one another in this way as compared to just having one beam slamming into a stationary target, yet this still how colliders are built. Consider the following two situations. In the first picture, (the modern collider design), two equal mass m particles collide, each with total energy Ecollider, to produce some exotic new particle of mass M, at rest. Conservation of energy says that 2Ecollider = Mc^2. On the other hand, in the second picture (the fixed-target design), a particle of mass m with energy Efixed hits an identical mass particle at rest, producing the same exotic new…arrow_forwardHome | bartleby ong that n245qhp7a?filename=Bord%2C%20Donald%20J.

In the Bohr model for hydrogen, the radius of the nth orbit can be shown to be »² times the radius of the first Bohr orbit = 0.05 nm (see Example 10.3). Similarly, the energy of an electron in the nth orbit is times its energy when in the - 1 orbit. What is the circumference of the n = 100 orbit? (This is the distance the electron has traveled after having revolved around the proton once.) For such large-n states, the orbital frequency is about equal to the frequency of the photon emitted in a transition from the nth level to an adjacent level with n + 1 or n - 1. Given this, find the frequency and corresponding period of the electron's orbit by computing the frequency associated with the transition 100 to n = 101. Using your values for the electron's orbital size (distance) and travel…arrow_forwardA Uranium 235 atom has 92 protons in the nucleus and has a mass of 3.92 E-25 kg.
