a. nine times greater than its weight on Earth’s surface.

d. the same as on the Earth’s surface.

b. thirteen times greater than its weight on Earth’s surface.

c. one thirteenth its weight on Earth’s surface.

What are similarities and differences of reflection, refraction, diffraction and absorption?

The electric potential v is constant everywhere within a certain region of space. which statement below is true? the choices are: the electric field is also constant (but not zero) within the region. a charged particle placed within the region will experience an electric force. the electric field is zero everywhere within the region. the electric field varies from place to place within the region.

Large electric fields in cell membranes cause ions to move through the cell wall. the field strength in a typical membrane is 1.0 x 10 7 n/c. what is the magnitude of the force on a calcium ion with charge +e? what is its acceleration? is it possible for a particle with the same charge as as calcium to have a different acceleration if placed at this location? what would change the acceleration: mass of the particle? diameter of the particle?
