Answer 1

Here are the answers to your questions:

14. According to Newton's second law, what happens when the same force is applied to two objects of different masses?

• b The object with greater mass will experience a smaller acceleration.
  (According to Newton's second law, \( F = ma \), when the same force is applied, acceleration is inversely proportional to mass.)

15. What happens to the volume of a gas when the temperature is increased?

• b The volume is increased.
  (According to Charles's Law, at constant pressure, the volume of a gas is directly proportional to its temperature in Kelvin.)

16. In what group and period does Barium (Ba) belong?

• C) Group 2, Period 6.
  (Barium is an alkaline earth metal located in Group 2 of the periodic table and is in Period 6.)

17. Match the description of nuclear decay to the type of nuclear decay.

• 1. 4 He 2 → B (Alpha)
• 2. 0 e -1 → A (Beta)
• 3. 0/0 Y → C (Gamma)
• 4. Can be stopped by paper → B (Alpha)
• 5. Can be stopped by aluminum → A (Beta)
• 6. Can be stopped by lead → C (Gamma)
