Question

physics answer please

Answer 1

ANSWER

Velocity ratio (V.R)

Velocity ratio is the ratio between the distance moved by the effort to the distance moved by the load.

$velocity \: ratio(</u><u>V</u><u>.</u><u>R</u><u>.</u><u>) = \frac{velocity \: of \: effort \: (</u><u>V.E</u><u>.</u><u>)}{velocity \: of \: load \: (</u><u>V.L</u><u>.</u><u>)}$

now.......

$</u><u>V</u><u>.</u><u>E</u><u>. =3 \: m \\ </u><u>V</u><u>.</u><u>L</u><u>.</u><u> =( 4 - 3)m = 1 \: m$

therefore....

V.R.=3/1=3

therefore..

effort=load/(V.R)

=(500/3) Newton

=166.67 N

Answer 2

Answer:

166.67 N

Explanation:

Velocity ratio is the ratio of distance traveled by the effort to the distance traveled by the load in the machine.

Velocity Ratio(VR) = Distance moved by effort/Distance moved by Load

∴ Effort = (500/3)

            = 166.67 N

Therefore, Effort = 166.67 N.
