50 points select all that apply. the following diagram shows the path of a planet around the sun. kepler discovered that area a = area b the distance from p 2 to p 3 is half the distance from p 5 to p 6 the speed in the interval from p 1 to p 2 is twice the speed in the interval from p 6 to p 1 the speed in the interval from p 1 to p 2 is less than the speed in the interval from p 3 to p 4

The correct answer is: B area = area

Explanation: You can solve this problem through the use of laws of Kepler's planetary motion. There are Kepler the laws ( 3 of them) In this exercise, we will use the second law. According to this law, a line segment joining a planet and the sun sweeps out areas is equal to that during the equal intervals of time

an ion is a charged atom or molecule. it is charged because the number of electrons do not equal the number of protons in the atom or molecule. an atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom.

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.
