"As the legend tells, Isaac Newton discovered the law of universal gravitation after an apple fell on his head. What happened with this great apple after it bounced off Newton's head?" People who visited a certain website were asked this question. Of 257 people who answered this question during the last month, 30% replied that Newton ate the apple.
Calculate the margin of error for this result. Round the percentage to one decimal place. Do not round intermediate steps.
QUESTION:
If 30% of 257 people replied that Newton ate the apple, the margin of error is?
Which of the following statements cannot be supported by Kepler's laws of planetary motion?
a The distance of a planet around the sun changes throughout its orbit.
b The speed a planet is moving around the sun changes throughout the year.
c The orbital period of Mercury can be calculated using the orbital period of Jupiter and the average distances of both planets.
d The age of the four largest planets can be determined using the age of the four smallest planets and the average distances of each planet.
The mass of Mars is 6.42 × 10^23 kg. Its moon Phobos is 9.378 x 10^6 meters away from Mars, with a mass of 1.06 × 10^16 kg and a period of 7.66 hours. It's moon Deimos has a mass of 1.4762×10^15 kg and a period of 30.3 hours. a) Use Kepler's 3rd law to determine the orbital distance between Mars and Deimos? b) What is the tangential velocity of Phobos, using the formula v(tangential) = sqrt (G x m(central)/ r)? c) What is the gravitational force of attraction between Mars and Phobos.
