1. If a rod travels with a speed v 0.8 c along its length, how much...
A rod has rest frame length ?0=4.3m, and is moving with speed v=0.31c relative to a stationary observer. What length of the rod ? does the observer measure? Answer in meters.
Suppose a rod of rest length L travels with speed 0.90c along the x-axis toward a garage of length L/2 (both lengths being in the x direction). 1. What is the length of the rod in the frame of the garage? Will it fit inside the garage? 2. Suppose once the rod is inside the garage, the garage door closes. What happens? Is possible for the rod and the garage to be infinitely strong, so that neither breaks?
A car P travels along a straight road with a con- stant speed v 65 mi/hr. At the instant when the angle θ 60°, determine the values of r in ft/sec and θ in deg/sec. r 7.7 dea 100
1) The Solar and Sidereal days difer from each other by about 4 minutes. How much distance, relative to the Sun and in km, does the Earth travel during that time? (You may approximate the Earth's orbit as a perfect circle.) 2) How many degrees does the Moon move in its orbit during one Earth-day. Use the Moon's orbital period relative to distant stars, i.e. use its sidereal period. 3) a) Since the Earth makes one full revolution every 24...

Submit Answer Save Progress 14. 14 points The radius of the earth's orbit around the sun (assumed to be circular) is 1.50 x 108 km, and the earth travels around this orbit in 365 days. (a) What is the magnitude of the orbital velocity of the earth in m/s? m/s (b) What is the radial acceleration of...
The speed of light, by the u symbol c, has a value, to two significant figures, of 3.0 x 108 m/s. (a) How long does it take for light to travel from the Sun to Earth, a distance of 1.5 x 10!1 m? (b) How Jong does it take light to travel from the moon to Earth, a distance of 3.8 x 108 m? 1.0 In free light travels in a straight line at constant speed, c g along a...
1 What is the Earth's orbital speed as it orbits the Sun. Take the Earth/Sun distance to be 93 million miles (taking the Earth's orbit to be circular), the mass of the Earth to be 5.97 X 102 kg and the mass of the Sun to be 1.987 X 10*0 kg. Solve this problem using Newton's 2nd law directly 2. A 55.7 kg mass is lifted (at a constant velocity) from the ground to a vertical height of 1275 m....
question 4-7 4. Travelling Waves and Their Characteristics A rope wave travels in the positive x -direction. You are also told that the speed of the wave is 1000 cm/s, its frequency is 200 Hz, and that the wave is subject to the following initial conditions: at x 0 and t = 0: y =-1 cm, and, at x = 0 and t : ar = +20 cm/s (this is the velocity of the point on the rope at horizontal...
please help and answer all ASAP please thank you so much Question 49 (1 point) When light travelling in glass enters glass with a higher index of refraction, the wave will be: a) partially transmitted with a change in phase b) transmitted forming a standing wave pattern in air c) reflected so as to form a node at the junction d) totally reflected at the junction e) partially reflected without a change in phase Question 38 (1 point) The charge,...
Consider a cylindrical capacitor like that shown in Fig. 24.6. Let d = rb − ra be the spacing between the inner and outer conductors. (a) Let the radii of the two conductors be only slightly different, so that d << ra. Show that the result derived in Example 24.4 (Section 24.1) for the capacitance of a cylindrical capacitor then reduces to Eq. (24.2), the equation for the capacitance of a parallel-plate capacitor, with A being the surface area of...
