Q: If diffraction were the only limitation, what would be the maximum

If diffraction were the only limitation, what would be the maximum distance at which the headlights of a car could be resolved (seen as two separate sources) by the naked human eye? The diameter of th...

Q: A hamster of mass 0.100 kg gets into its exercise

A hamster of mass 0.100 kg gets into its exercise wheel and starts to run at t = 0. After t = 0.800 s, the wheel turns with a constant rotational frequency of 1.00 Hz. What is the tangential accelerat...

Q: In bright light, the pupils of the eyes of a cat

In bright light, the pupils of the eyes of a cat narrow to a vertical slit 0.30 mm across. Suppose that a cat is looking at two mice 18 m away. What is the smallest distance between the mice for which...

Q: The maximum height of a cylindrical column is limited by the compressive

The maximum height of a cylindrical column is limited by the compressive strength of the material; if the compressive stress at the bottom were to exceed the compressive strength of the material, the...

Q: A clothes washer reaches an angular speed of 1400 rev/min

A clothes washer reaches an angular speed of 1400 rev/min in 2.0 s, starting from rest, during the spin cycle. (a) Assuming the angular acceleration is constant, what is its magnitude? (b) How many...

Q: Light with a wavelength of 660 nm is incident on two slits

Light with a wavelength of 660 nm is incident on two slits and the pattern shown in the figure is viewed on a screen. Point A is directly opposite a point midway between the two slits. What is the pat...

Q: A wheel’s angular acceleration is constant. Initially its angular velocity is

A wheel’s angular acceleration is constant. Initially its angular velocity is zero. During the first 1.0 s time interval, it rotates through an angle of 90.0°. (a) Through what angle does it rotate d...

Q: A thin layer of an oil (n = 1.60

A thin layer of an oil (n = 1.60) floats on top of water (n = 1.33). One portion of this film appears green (λ = 510 nm) in reflected light. How thick is this portion of the film? Give the three small...

Q: A car that is initially at rest moves along a circular path

A car that is initially at rest moves along a circular path with a constant tangential acceleration component of 2.00 m/s2. The circular path has a radius of 50.0 m. The initial position of the car is...

Q: The Very Large Array (VLA) is a set of 30

The Very Large Array (VLA) is a set of 30 dish radio antennas located near Socorro, New Mexico. The dishes are spaced 1.0 km apart and form a Y-shaped pattern, as in the diagram. Radio pulses from a d...
