A horizontal net force F is exerted on an object at rest. The object starts at x = 0 m
m
and has a speed of 8.0 after moving
6.0 m along a horizontal frictionless
surface. The net force F as a function of
the object's position x is shown below

What is the mass of the object

the device is called “ rocket engine”

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

d. platinum would have the greatest temperature increase because it has the lowest specific heat.
