Particles pass through a single slit of width 2.3 mm. The de Broglie wavelength of each particle is 515 nm. After the particles pass during the slit, they spread out over a range of angles. Suppose that the uncertainty in the position of the particles is one-half the width of the slit, and utilize the Heisenberg uncertainty principle to decide the minimum range of angles.
a car weighs 2415 pounds and the rocket mounted on the car provides 1500 lbs of constant thrust. calculate the distance in feet traveled in this time
It is important for the body to have mechanisms to effectively cool itself; if not, moderate exercise could easily increase body temperatures to dangerous levels. by how much would his body temperature rise during this exercise
To focus a camera on objects at dissimilar distances, the converging lens is moved toward or away from the image sensor, so a sharp image always falls on the sensor. A camera with a telephoto lens (f= 200.0mm) is to be focused on an object located fi..
Your forensic chemistry group, working closely with local lawenforcement agencies, has acquired a mass spectrometer similar tothat discussed in the text. It employs a uniform magnetic field that has a magnitude of 0.80 T
An 8g bullet is fired at a speed of 216 m/s into a 190 g block that is initially at rest at the edge of a table of 1m height. The bullet fully embeds itself in the block before the bullet-block system launches off the table. How far in the x-direc..
A 0.335 kg iron horseshoe that is initially at 420°C is dropped into a bucket containing 20.3 kg of water at 22.1°C. What is the final equilibrium temperature (in °C)? Neglect any heat transfer to or from the surroundings. Do not enter units.
An air track glider undergoes a perfectly inelastic collision with an identical glider that is initially at rest. What fraction of the first gliders initial kinetic energy is transformed into thermal energy in this collision?
A rocket, which is in deep space and initially at rest relative to an inertial reference frame, has a mass of 53.1 x 10^5 kg, of which 3.81 x 10^5 kg is fuel. What is the rocket's thrust
A charge of -1.0 µC is located at the origin, a second charge of 2.6 µC is located at x = 0, y = 0.1 m, Find the forces that act on each of the three charges
