Dewayne reviews kepler’s laws by making the table shown. which label belongs in each cell of the table? w: the orbital period is related to the average distance from the sun. x: orbit are ellipses with the sun at a focus. y: a planet sweeps out equal areas in equal time frames as it orbits the sun. choices: a. w: first x: second y: third b. w: third x: second y: first c. w: third x: first y: second d. w: second x: third y: first

There are three laws which are postulated by Kepler for planetary motion.

Kepler's first law: As per the first law of Kepler,the orbits of planets around the sun is elliptical in nature in stead of circular. The sun is situated always at one of its foci.

Second law: Planets are moving in such a way that the areal velocity of the planets are constant i.e planets sweep out equal ares in equal interval of time.

Third law: The square of time period of planets around the sun is directly proportional to the cube of semi major axis.

where T is the time period and R is semi major axis.

Hence the correct answer to the question is C i.e third,first,second.

two charges are fixed in place on the x-axis as shown. the charge at x = 0 is negative and has magnitude q = 2 μcoulombs (1 μcoulomb = 10-6 coulombs). the charge at x = d, (d = +12 cm), is positive and has magnitude q = 4 μcoulombs. find a point x = xo along the x-axis at which the electric field is zero.
