What is the answer in this question. (a+b)(a+b)
Answer:
=a²+2ab+b²
Step-by-step explanation:
(a+b)(a+b)
=(a+b)(a+b)

What Are The Forces Belong To Contact Force?
What are the forces belong to contact force? Answer: The Contact Forces are the Frictional Force , Tension Force , Normal Force , Air Resistance Force , Applied Force , and Spring Force . Frictional Force - the force resisting the relative motion of solid surfaces, fluid layers, and material elements rubbing against each other (e.g. A ball rolling on the floor) Tension Force - the pulling force transmitted axially by the means of a string, cable, or chain (e.g. A chandelier) Normal Force - a support force exerted upon an object that is in contact with another stable object (e.g. A book on a table) Air Resistance Force - the force of air pushing against a moving object (e.g. A piece of paper falling) Applied Force - the force applied to an object by a person or another object (e.g. A person using a hammer to strike a nail) Spring Force - the force exerted by a compressed or stretched spring upon any object that is attached to it
