Question

1. analyze the graph. which statement most accurately reflects the graph and data and shows the relationship of the mass of a javelin to its expected energy? a. as the mass of the javelin increases, the expected energy of the javelin increases in proportion to the change of mass. b. as the mass of the javelin decreases, the expected energy of the javelin increases in proportion to the change of mass. c. as the mass of the javelin increases, the expected energy of the javelin decreases in proportion to the change of mass. 2. if the javelin mass increased to 1.6 kg, how would that affect the data in the table? complete the following sentence. the energy will ......................... if the ........................ remains the same.

Explanation:

Step1: Analyze the graph trend

The graph shows a positive - slope linear relationship between energy and mass. As mass increases, energy increases.

Step2: Evaluate each option

Option a correctly describes this positive - proportional relationship. Option b and c are incorrect as they describe inverse relationships.

Step3: For the second part

Based on the direct - proportional relationship shown in the graph, if other factors remain the same, when the mass of the javelin increases, the energy will increase.

Answer:

1. a. As the mass of the javelin increases, the expected energy of the javelin increases in proportion to the change of mass.
2. The energy will increase if the other factors remain the same.
