When you use floating for a two-column, fixed width page layout, you need to a. make sure the body element is wide enough for the columns b. float just the second column element to the right c. make sure the column elements are tall enough for their contents d. float both columns to either the right or left

Option A : make sure the body element is wide enough for the columns

Explanation: The best practice for when using floating for two column and the widths are fixed is to ensure the body element is wide enough for the separate columns.

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.

i really dont know but i will try okay.

so i think u would just add all them up and get your answer..
