A vector has Ans✓✓✓Magnitude and direction
What is a team Ans✓✓✓a small group of people with complementary
skills who are committed to a common purpose, performance goals, and
approach for which they hold themselves mutually accountable
Newton's First Law Ans✓✓✓An object at rest stays at rest and an object
