Arm's length) ol rädius 0.0 discus. 12. 5. (ii) suppose the space shuttle is in orbit 400 km from the earth's surface, and circles the earth about once every 90 minutes. find the centripetal acceleration of the spac shuttle in its orbit. express your answer in terms of g, the gravitational acceleration at the earth's surface. 6. (ii) what is the magnitude of the acceleration of a speck of clay on the edge of a potter's wheel turning at 45 rpm (revolutions per minute) if the wheel's diameter is 32 cm? 7. (ii) a ball on the end of a string is revolved at a uniform rate in a vertical circle of radius 72.0 cm, as shown in fig. 5-33. if its speed is 4.00 m/s and its mass is 0.300 kg, calculate the tension in the string when the ball is (a) at 13. the top of its path, and (b) at the bottom of its path. tl

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

Under normal conditions, describe how increasing the temperatures effects the solubility of a typical salt

Your science teacher brings in a speaker to talk to your class about climate change. during the session, students ask a few questions. which questions are related to the current evidence on climate change
