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
is the distance over which the input force is applied.
Let
is the distance over which the output force is applied.
The ideal mechanical advantage of the system is calculated as -
IMA =
.
Both
are measured in distance unit.
Hence, IMA is a unitless physical quantity.
If it is about the hydrogen fusion in main sequence stars, where the temperature of the center or the core rises the same time as the mass does, which results of the PP process is domination the process particularly in low masses. This is just one example of the step that percedes the onset of hydrogen fusion.
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.
