1. Since sleep is so important, we might wonder why people so often fail to get a sufficient amount of sleep. What factors do you think are most important in preventing people from getting enough
sleep?
2. What factors prevent you from getting enough sleep in your own life?
3. How could factors that prevent people from getting enough sleep be addressed? If you were
designing an intervention to promote healthy sleep, what would you try to do?
4. Some careers involve regular sleep deprivation (e. g., flight attendants and jet lag: doctors and
night shifts). How does learning about sleep deprivation change your opinion about these
careers? Should they be regulated in some way, and if so, how?

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

The force it would take to accelerate an 900-kg car at the rate of 6m/s2

Juliette sets the initial velocity to +10 m/s, the acceleration to zero, and clicks “start.” how can shakina describe the subsequent motion of the car juliette controls?
