The figure shows the circular wave fronts emitted by two sources, the wavelength for both idential waves is 1.4 m. What is the path-length difference at point Q, in meters? Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.

What is the intensity of the light falling on the center of the screen?b. What is the intensity of light falling on the edge of the screen?Formula:E = I/d^2 Where : E = is the intensity of the light on the object,lux (lx) or foot candleI = is the intensity of the light at the source,lumen (lm)d = is the distance of the light source from the object,meters or ft. Example Problem1. If the magazine is 2m from the 100 lumen source, what is the intensity of the light failing on themagazine?E = I/d2E = 100/22E = 25 lux
(a) Seismographs measure the arrival times of earthquakes with a precision of 0.100 s. To get the distance to the epicenter of the quake, geologists compare the arrival times of S- and P-waves, which travel at different speeds. If S- and P-waves travel at 4.00 and 7.20 km/s, respectively, in the region considered, how precisely can the distance to the source of the earthquake be determined? (b) Seismic waves from underground detonations of nuclear bombs can be used to locate the test site and detect violations of test bans. Discuss whether your answer to (a) implies a serious limit to such detection. (Note also that the uncertainty is greater if there is an uncertainty in the propagation speeds of the S- and P-waves.)

W/m (b) Suppose you were floating in space and pointed the laser beam away from you. What would your acceleration be? Assume your total mass, including equipment, is 74.8 kg and that the force is directed through your center of mass. Hint: The change in momentum is the same as in the nonreflective case. We know that the acceleration of an object is given by Newton's second law. How do we determine the net force acting on the accelerating object in this case? m/s (c) Calculate your acceleration if it were due to the gravity of a space station with mass 1.06 x 10° kg and center of mass 117.1 m away. m/s2 (d) Calculate the peak electric and magnetic fields of the laser.

The image on the right shows a distant object in motion. What is the behavior of the object? O The light is red shifted and the object is moving away from Earth. O The light is blue shifted and the object is moving towards Earth. O The light is blue shifted and the object is moving away from Earth. O The light is redshifted and the object is moving towards Earth.
