A LASER is a source of very intense, monochromatic, and unidirectional beam of light. These properties of a laser light can be exploited to measure long distances. The distance of the Moon from the Earth has been already determined very precisely using a laser as a source of light. A laser light beamed at the Moon takes 2.56 s to return after reflection at the Moon’s surface. How much is the radius of the lunar orbit around the Earth ?

- A laser with 7.6 watts of power has a diameter of 13 cm. It's directed at the surface of a silver lined reflecting satellite in space with a mass of 75 kg. If the diameter of the satellite is greater than 20 cm what's the acceleration of the satellite and how long will it take to reach a speed of 15 km/s?arrow_forwardA fiber optic gyroscope is a fascinating device used to measure rotation rate (angular velocity), which is a necessary parameter to be measured in through autonomous navigation systems (inertial navigation). They are based on an interferometer conceived in 1913 by the French physicist Georges Sagnac. In a Sagnac interferometer, a beam of light is split and the two beams are made to follow the same path but in opposite directions. On return to the point of entry the two light beams are allowed to exit the fiber loop (see Figure and undergo interference. If the loop rotates clockwise, the clockwise optical path becomes longer than the counterclockwise optical path (see Figure 2). The phase difference (interference) is proportional to the rotation rate (angular velocity). Derive this relationship for a fiber optic gyroscope that uses a 1 km long fiber aranged in a 25 cm spool and a laser beam with wavelength of 1.5 um.

- You might have noticed that emergency vehicles such as ambulances are often labeled on the front hood with reversed lettering (e.g., ECNALUBMA). Explain why this is so.arrow_forwardThe high noon sun shines straight down on an airplane that is climbing through the atmosphere at an angle of 8.0° from horizontal. The plane's climb rate is 750 meters per minute. This the rate at which its altitude increases. (a) What is the speed of the airplane? (b) What is the speed of the plane's shadow crossing the flat desert below?arrow_forwardCASE STUDY In Example 34.6 (page 1111), we imagined equipping 1950DA, an asteroid on a collision course with the Earth, with a solar sail in hopes of ejecting it from the solar system. We found that the enormous size required for the solar sail makes the plan impossible at this time. Of course, there is no need to eject such an object from the solar system: we only need to change the orbit. A much more pressing problem is Apophis, a 300-m asteroid that may be on a collision course with the Earth and is due to come by on April 13, 2029. It is unlikely to hit the Earth on that pass, but it will return again in 2036. If Apophis passes through a 600-m keyhole on its 2029 pass, it is expected to hit the Earth in 2036. causing great damage. There are plans to deflect Apophis when it comes by in 2029. For example, we could hit it with a 10- to 150-kg impactor accelerated by a solar sail. The impactor is launched from the Earth to start orbiting the Sun in the same direction as the Earth and Apophis. The idea is to use a solar sail to accelerate the impactor so that it reverses direction and collides head-on with Apophis at 8090 km/s and thereby keeps Apophis out of the keyhole. Consider the momentum in the impactors orbit (Fig. P34.75) when the solar sail makes an angle of = 60 with the tangent to its orbit. Current solar sails may be about 40 m on a side, but the hope is to construct some that are about 160 m on a side. Estimate the impactors tangential acceleration when it is about 1 AU from the Sun. Keep in mind that the sail is neither a perfect absorber nor a perfect reflector, and a heavier impactor would presumably be equipped with a larger sail. Dont be surprised by what may seem like a very small acceleration. FIGURE P34.75arrow_forward

Find the magnitude and direction of the force exerted on the diving board (a) by pillar A. (b) by pillar B.arrow_forward4. Given: Three forces act on particle P. Force A has a magnitude of 15 N and acts 60° CCW from the positive x-axis. Force B has a magnitude of 60 N and acts along a ray from point P with a slope of -4/3. Force C has a magnitude of 10 N and acts straight left (180° CCW from positive x- axis). Find the Rectangular Components: a. Draw a neat, scaled, labeled diagram representing particle P and the three forces acting on it. b. Find the scalar components of A, B, and C. Remember, scalar components use a sign to indicate direction along their line of action.arrow_forward
