- (1) 8) Solve the following word problem. Zeta runs across a football field that is close to 100 meters long in 35 seconds. What is her speed? 2.9m/s 3500m/s 0.35m/s 29m/s
- What is the best definition of heat? Heat is described as molecules that are vibrating The more they vibrate.the more heat they have. Heat occurs when little balls of energy are absorbed by different objects. Heat is a property of matter. All matter has a certain amount of heat based on its temperature. Heat is one of the elements on the periodic table. It is represented by the letters He.
