How do the electrical force and the gravitational force compare?
The table lists the values of the electrical force and the
gravitational force between two protons.
Type
Force (N)
Electrical
6.26 x 10-32
Gravitational
5.02 x 10-08
The electrical force is 1.2 x 1036 times less than the
gravitational force.
The electrical force is 1.2 x 1036 times greater than the
gravitational force.
The electrical force is 8.0 10-37 times less than the
gravitational force.
The electrical force is 8.0 x 10-37 times greater than the
gravitational force.

1. what is the relationship between wavelength and the penetrating power of an electromagnetic wave? a) the penetrating power has no relationship to the wavelength. b) the penetrating power increases as the wavelength increases. c) the penetrating power decreases as the wavelength increases. d) the penetrating power decreases as the wavelength decreases. 2. as ice melts and turns into water, the speed of sound through the material would most likely do what? justify your answer. a) the speed would not change because the material is always water. b) the speed of sound would increase because the density of water is less than that of ice. c) the speed of sound would increase because energy is added to ice in order to make it melt. d) the speed of sound would decrease because sound travels faster through solids than liquids. 3.which of these waves need a medium to travel through? a) sound b) x-rays c) infrared rays d) visible light
