Masses of the planets are easiest to determine if:
A) they are terrestrial and the extra size of the planet's disk can be measured. B) they are jovian and their oblateness can be found. C) they have natural satellites whose motions can be precisely measured. D) they are dense and easily deflect the path of passing spacecraft. E) they move rapidly and their periods are easily measured.
Treat each of your eyes as a circular aperture of diameter 3.5 mm. Light of wavelength 500 nm is used to view two point sources that are 894 m distant from you
How far apart must these two point sources be if they are to be just resolved by your eye? Assume that the resolution is diffraction limited and use Rayleigh's criterion.
A damped harmonic oscillator, with a damping force proportional to its speed, is oscillating with an amplitude of 0.500 cm at t = 0
When t = 8.20 s, the amplitude has died down to 0.400 cm. At what value of t will the oscillations have an amplitude of 0.250 cm? A) 18.5 s B) 20.5 s C) 16.5 s D) 25.5 s E) 5.13 s
A 2.0-kg block slides on a rough horizontal surface. A force (magnitude P = 4.0 N) acting parallel to the surface is applied to the block. The magnitude of the block's acceleration is 1.2 m/s2 . If P is increased to 5.0 N, determine the magnitude of the block's acceleration
a. 2.1 m/s2 b. 2.3 m/s2 c. 1.9 m/s2 d. 1.7 m/s2 e. 3.2 m/s2
