If you weigh 660 n on the earth, what would be your weight on the surface of a neutron star that has the same mass as our sun and a diameter of 19.0 km ? take the mass of the sun to be ms = 1.99×1030 kg , the gravitational constant to be g = 6.67×10? 11 n? m2/kg2 , and the acceleration due to gravity at the earth's surface to be g = 9.810 m/s2 . express your weight wstar in newtons.

Can you think of a way a rock unit with an older fossil could be above a rock until with a younger fossil? describe the scenario.

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 number of passengers who arrive at the platform of a subway station for the 10 am train is a random variable with a mean of 120 and a variance of 16. find the lower bound of the probability that there will be between 100 and 140 passengers (round off to second decimal place).
