- A clock battery wears out after moving 10,000 C of charge through the clock at a rate of 0.500 mA. (a) How long did the clock run? (b) How many electrons per second flowed?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.

- By the time he was forty years old, Benjamin Franklin had made enough money in various business enterprises to live comfortably for the rest of his life. At this time he decided to devote his energy to scientific investigations. It wasn’t until he was nearly 50 years old that he began his career as a statesman. When he was experimenting with atmospheric electricity and lightning, Franklin naturally wanted to know when a charged thundercloud was approaching. He set up the alarm shown here. Briefly explain how it worked.arrow_forwardHybrid vehicles are powered by a gasoline engine paired with an electric motor and batteries. Hybrids get much better mileage in the stop and go of city driving than conventional vehicles do. When you brake to a stop in a conventional car, friction converts the kinetic energy of the car’s motion into thermal energy in the brakes. In a typical hybrid car, depressing the brake pedal will connect a generator that converts much of the car’s kinetic energyinto chemical energy in a battery. Explain how this makes a hybrid vehicle more efficient.arrow_forwardI start with a pair of positive charges a set distance apart at rest. Then, I let go. Which of the following describes the subsequent behavior of the system? A The charges move toward each other. Their speed increases until they collide. B The charges move apart. The speed keeps increasing through time. C The motion is unpredictable. D There is a force at right angles to the motion at any time, so as the charges move apart, they each move in a spiral. E The charges move apart. The speed increases at first, but falls to zero as tehy get very far apart. F There is a force at right angles to the motion at any time, so as the charges move toward each other, they each move in a spiral. G The charges move apart. The speed keeps decreasing through time.arrow_forward
