a stone can slide down one of four different frictionless ramps, as shown in the figure. for which ramp will the speed of the ball be the greatest at the bottom?

i think if it were me i whould divide 300 dide 15

step-by-step explanation:

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this
