A rocket ship flies past the earth at 88.0 % of the speed of light. Inside, an astronaut who is undergoing a physical examination is having his height measured while he is lying down parallel to the direction the rocket ship is moving.

Suppose the astronaut in part A gets up after the examination and stands with his body perpendicular to the direction of motion. What would the doctor in the rocket measure for his height now?

the height will increase relativistically to 4.127m

This is because height increases as one approaches the speed of light c

Explanation:

The height of the astronaut in the ship is not indicated in this part of the question but I'll assume that it is the same as that of the other question where the height is 1.96m.

NB: if the height for this question is not 1.96m then substitute the actual value of the height as h', in h'÷0.4749 to get answer.

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
