You are designing a new roller-coaster. The main feature of this particular design is a vertical circular loop. At the top of the loop, riders will feel like they are weightless when they are completely upside-down. Explain why such an effect is independent of the mass of the rider. Compute the radius of the loop required for this effect to occur if the coaster start at rest a height of 80m above the ground, speeds up as it descends to ground level, and then enters the loop.(You can assume that the coaster rolls on the track without friction).

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

false.

explanation:

this statement is false. after falling for 5 seconds, its speed will not be 100 m/s.
