- A student is asked to describe the path of a paper airplane that is thrown in the classroom. Which statement best describes the path of the paper airplane? The paper airplane will move in a straight line, according to Newton's first law of motion. The paper airplane will drop straight to the ground once its inertia gives in to the force of gravity. The paper airplane will create a curved path toward the floor as it is pulled toward Earth's center. The paper airplane will orbit around the desk because it is the object with the largest mass in the rc
- A celebrity chef is looking for a metal -plated pan that she can heat to the highest temperature possible for a given input of energy. Her different pan options are: copper, iron, and aluminum. All of the pans have the same mass. Based on the metal's specific heat capacities shown , the chef should choose a pan made from iron because it undergoes the largest temperatule change for a given input of energy. Specific Heat in J/g^circ C
