springs in series

What is the spring constant for two identical springs connected in series?

• Half of the original spring constant
• The original spring constant
• Twice the original spring constant
• Four times the original spring constant

What happens to the spring constant when two springs with different spring constants are connected in series?

• It increases
• It decreases
• It stays the same
• It depends on the spring constants

How does the extension of a spring in a series system compare to the extension of each individual spring?

• The extension is less than each individual spring
• The extension is greater than each individual spring
• The extension is the same as each individual spring
• It depends on the spring constant

What is the effect of adding more springs in series to a system?

• The spring constant increases
• The spring constant decreases
• The extension increases
• The extension decreases

If two springs are connected in series and a 20 N force is applied, what is the tension in each spring?

• 10 N
• 20 N
• 30 N
• 40 N
