The unit for IMA is _____. newtons joules meters IMA is unitless
Sonja [21]

The correct answer to the question is unitless i.e the IMA of a mechanical system has no unit.

EXPLANATION:

The IMA of a mechanical system stands for ideal mechanical advantage.  It can be defined as the number of times the input or effort force provided to the mechanical system is multiplied under ideal conditions. The ideal conditions means that the system is free from friction, air resistance etc.

Let us consider d_{i} is the distance over which the input force is applied.

Let d_{0} is the distance over which the output force is applied.

The ideal mechanical advantage of the system is calculated as -

                    IMA = \frac{d_{i}} {d_{0}}.

Both d_{i}\ and\ d_{0} are measured in distance unit.

Hence, IMA is a unitless physical quantity.

QveST [7]

Answer:

A) motion parallax

Explanation:

Motion parallax is a visual perception while we are in motion with respect to our surrounding in which the surroundings objects nearer to our eyes appear to move or pass at a faster pace than the objects farther to our eyes during the motion.

This can also be understood as the angular displacement of the objects while our motion. The objects nearer to our eyes have a rapid change in the angular position than the objects far away from us.
