The statemengt is <em>false</em>. Electromgnetic waves do not require a medium to transfer energy. They can transfer energy through vacuum (empty space with nothing in it). If electrimagnetic waves needed a medium to move through from place to place, then we could never see the sun, and also it would get very cold here.
Friction affects forward motion because the friction slows something down and wears it to the Bone

Even though im ot giving you the whole answer I can tell you what to do and why to do it. If what you need is to find the Electric field of something you need to use the formula for that wich is E = kQ/r2 where k is a constant with a value of 8.99 x 109<span> N m</span>2/C2., Q is <span>a charge of magnitude and you have also the ratio. So replace the simbols with the data they give you. I know thi will help you</span>
