Read the passage.

People should consider the impact of drones before buying (and flying) one. Think about where you will fly your drone. There’s a difference between flying in close, tight civilization and the wide-open, vast wilderness. Also, some communities have laws regulating drone use. For example, Florida law requires recreational drones to be registered with the Federal Aviation Administration (FAA). Safety should always be of the utmost concern. Flying away from power lines and keeping a respectable distance from people and wildlife will ensure that no one (or no animal) is harmed should the drone operator mistakenly send it in the wrong direction. Drones of the twenty-first century are the Red Ryders of the 1940s. As this device becomes more popular and common, people should take care to be responsible drone operators.

Which statement best expresses the claim?

Drones can cause damage to power lines.
People should fly their drones responsibly.
Drones are regulated by law in many areas.
People should be required to register their drones.

First, launch the video below. you will be asked to use your knowledge of physics to predict the outcome of an experiment. then, close the video window and answer the question at right. you can watch the video again at any point. part a as in the video, we apply a charge +q to the half-shell that carries the electroscope. this time, we also apply a charge –q to the other half-shell. when we bring the two halves together, we observe that the electroscope discharges, just as in the video. what does the electroscope needle do when you separate the two half-shells again? view available hint(s) as in the video, we apply a charge + to the half-shell that carries the electroscope. this time, we also apply a charge – to the other half-shell. when we bring the two halves together, we observe that the electroscope discharges, just as in the video. what does the electroscope needle do when you separate the two half-shells again? it deflects more than it did at the end of the video. it deflects the same amount as at end of the video. it does not deflect at all. it deflects less than it did at the end of the video. submit

Two manned satellites approaching one another at a relative speed of 0.550 m/s intend to dock. the first has a mass of 2.50 ✕ 103 kg, and the second a mass of 7.50 ✕ 103 kg. assume that the positive direction is directed from the second satellite towards the first satellite. (a) calculate the final velocity after docking, in the frame of reference in which the first satellite was originally at rest.(b) what is the loss of kinetic energy in this inelastic collision? (c) repeat both parts, in the frame of reference in which the second satellite was originally at rest. final velocity(d) loss of kinetic energy = ?
