Cart A with a mass of 8 kilograms rolls to the right at 15 meters per second. Cart B with a mass of 9 kilograms rolls to the left at 11 meters per second. After they collide, Cart B is rolling to the right at 2 meters per second. (Neglect friction) Calculate the magnitude of block A’s velocity after the collision. Claim:
Evidence:
Reasoning:

second mirror gathers light from a faraway object and reflects it to another mirror. - a.

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.

hi i’m sorry to call us today so we will get back with y’all and we will have to do it haha omg was the day

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
