Final answer:
The correct statement is that Spring 1 has a speed of 4 m/s, which is half the speed of Spring 2 that travels at 8 m/s. Therefore, the correct option is a) Spring 1 has a speed of 4 m/s.
Step-by-step explanation:
If the speed of pulses in spring 2 is 8 m/s, which is twice the speed in spring 1, then the correct statement would be: Spring 1 has a speed of 4 m/s. This is because if spring 2's speed is double that of spring 1, we simply divide the known speed of spring 2 by 2 to find spring 1's speed. Therefore, spring 1’s speed would be 8 m/s / 2 = 4 m/s.
A spring is a flexible elastic object, typically made of metal, that can store mechanical energy when it's stretched or compressed and return to its original shape when the force is removed. Springs are used in various applications due to their ability to absorb and release energy.
Here are some key points about springs:
Types of Springs: There are different types of springs, including:
Compression Springs: These springs compress when a force is applied along their axis. They store potential energy in the form of strain energy.
Tension Springs (or Extension Springs): These springs extend when a force is applied along their axis. They also store potential energy as strain energy.
Torsion Springs: These springs store energy by twisting or torsion. They're used in applications where rotationally applied forces are involved.
