Assume that a force acting on an abject is given by f⃗ = a x ihat + b y jhat, where the constants a = 3.0n/m and b = 4.0n/m. determine the work done on the object by this force as it moves in a straight line from the origin to r⃗ = (10 ihat + 20 jhat) m.

W = 950J

Explanation:

From the problem we have these values:

F = [3x,4y]N

ΔX = 10m

ΔY = 20m

correct it is c.) b b

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
