What is the deviation?

Deviation in physics means the measure of variations of N points and it's average value. To simple terms, it means the difference between  a value of an measurement or a observation.

If this is the normal deviation word, it just means that you are doing something out the ordinary that doesn't seem normal or acceptable at all.

answer: point c: b. 1/2 potential, 1/2 kinetic, point a: 3/4 of its potential energy, point d or b: 3/4 potential, 1/4 kinetic

explanation: i cant explain. it's difficult to explain.

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper.
