1) Inhabitants of the fifth planet in a solar system on the other side of the Galaxy measure distance in units called “ladoladelums” and time in units called “forevers”. They observe that, a) all the planets in their solar system are much smaller than their Sun,
b) all planets have nearly circular orbits,
c)the fourth planet is about 32 ladoladelums from their Sun and completes one revolution in about 47 forevers, and
d) the third planet completes one revolution in 13 forevers.
Question: About how far from their Sun does the third planet lie?

Which statement best describes resistance? resistance is a. how well a current will flow in a material and is measured in volts. b. how well a material conducts an electrical charge and is measured in ohms. c. the ability of a material to attract a positive charge to create a current. d. the ability of a material to repel neutral charges and is measured in ohms.

Infrared rays have a shorter wavelength than question 11 options: x-rays. ultraviolet rays. radio waves. gamma rays.

Electric field of the earth. the earth has a net electric charge that causes a field at points near its surface equal to 150 n> c and directed in toward the center of the earth. (a) what magnitude and sign of charge would a 60-kg human have to acquire to overcome his or her weight by the force exerted by the earth’s electric field? (b) what would be the force of repulsion between two people each with the charge calculated in part (a) and separated by a distance of 100 m? is use of the earth’s electric field a feasible means of flight? why or why not?
