The existence of the dwarf planet pluto was proposed based on irregularities in neptune's orbit. pluto was subsequently discovered near its predicted position. but it now appears the discovery was fortuitous, because pluto is small and the irregularities in neptune's orbit were not well known. to illustrate that pluto has a minor effect on the orbit of neptune, calculate the acceleration due to gravity at neptune, in m/s2, due to pluto when they are 4.50x1012 m apart, as they are at present. the mass of pluto is 1.4x1022 kg.

The crank oa rotates in the vertical plane with a constant clockwise angular velocity ω0 of 5.6 rad/s. for the position where oa is horizontal, calculate the force under the light roller b of the 10.6-kg slender bar ab.

Explain the difference between each pair of concepts. a. frequency and relative frequency b. percentage and relative frequency a. select the correct choice below. a. frequency is the total number of observations in a data set. relative frequency is the number of times a particular distinct value occurs. b. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of a value to the total number of observations. c. frequency is the total number of observations in a data set. relative frequency is the ratio of the number of times a particular distinct value occurs to the frequency. d. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of two different values.
