D. magnetic
b. potential c. chemical
4. if work stays the same and distance is increased, then
a. less
b. more
c. the same
force will be needed.
d. no

a. less

Explanation:

The work done on a system is defined as the product of force and displacement. It is stored as the energy in the system.

The formula for work is given by

                         W = F x S    joules

where F - force

           S - displacement

From the above equation, if the work remains constant when the distance is increased, then the quantity of force should be reduced.

they are non-matter

explanation:

they are non-matter. basically, any type of energy or any abstract concept is an example of something that does not matter. other examples include dreams, magnetism, radio, and hate
