Two satellites, x and y, are orbiting earth. satellite x is 1.2 × 10^6 m from earth, and satellite y is 1.9 × 10^5 m from earth.
which best compares the satellites? satellite x has a greater period and a faster tangential speed than satellite y. satellite x has a greater period and a slower tangential speed than satellite y. satellite x has a shorter period and a faster tangential speed than satellite y. satellite x has a shorter period and a slower tangential speed than satellite y.

These models show the electron structures of two different nonmetal elements. which element is likely more reactive, and why? element 1 is more reactive because it has fewer electron shells and is toward the top of its group on the periodic table. element 1 is more reactive because it has more electrons in its valence shell and is farther to the right on the periodic table. element 2 is more reactive because it does not have a valence shell close to the nucleus, so it will attract electrons. element 2 is more reactive because it does not have a full valence shell, so it will attract electrons.

An artificial satellite circles the earth in a circular orbit at a location where the acceleration due to gravity is 6.03 m/s^2. determine the orbital period of the satellite.

How are the crust and the inner core alike? a) they are both solid. b) they both have the same temperature. c) they are both under the same pressure. d) they are both very close to the center of the earth.
