Proper Length

The theory of special relativity explains the connection between space and time to objects that move in a straight line at a constant speed. The objects move at the speed of light. When an object approaches light speed, its mass is endless and cannot move faster than light. The most crucial postulate of Einstein's special relativity is that the laws of nature do not change in each frame of reference.

The coefficient of friction between blocks is us = 0.4, at what angle will the block start sliding if it is initially at rest? Solution Let us obtain the net force in the axis perpendicular to the inclined plane. By virtue of the first law of motion (equilibrium), the net force is 2 Fperpendicular =n - Fgperpendicular = Thus, the normal force is n= m Cos On the axis parallel to the inclined, the net force is E FI| - Fg||-fs.max = Substituting the forces, we get the following: mg smg By simplifying, we get the following: tan(theta) = mus
The difference in absolute magnitude between two objects at the same distance is related to their fluxes by the flux-magnitude relation. FA FB = 2.51(MB − MA) A distant galaxy contains a type I classical Cepheid whose period results in an absolute magnitude estimate of −6.3. If this star were placed next to our Sun (M = +4.8) and you observed them both from the same distance, how much more flux would the Cepheid emit than the Sun? FCepheid FSun = If a galaxy contains a supernova that at its brightest has an apparent magnitude of +11, how far away is the galaxy? Assume that the absolute magnitude of the supernova is −18.

The figure above shows the light-curve obtained from continuous monitoring of the flux received from a star. Assuming that the dips arise because a planet orbiting the star passes between it and the observer once per orbit, estimate the orbital period (in days), the orbital semi-major axis (in Astronomical Units), and the physical radius of the planet (in units of the Earth’s radius). The star has a mass of 1.47 M⊙ and a radius of 1.84 R⊙.
