This prevents resistance or reduces it. Because the slope makes it move much faster.

What if i just write to increase the speed?

That is correct, but in physics answers are never that simple.

The speed increases for what? To reduce friction and resistance.

Thats what i hate :'( ..

Can anyone define properly frequency, wavelength and speed please ? =[ i alwaysss get confused

freq: no. of complete oscillations in 1 sec, wavelength: distance between 2 crests or troughs and speed umm the distance travelled by the time taken ..

yeah, speed is freq*wavelength though

thats wavespeed i thought just "speed"

np lets see hwz ur preparation State why electrical energy is transmitted at high voltage.

ummm as its more efficient ,,where is it asked?
