Answer the following questions...

1.

A spring has a length of 0.250 m when a 0.29-kg mass hangs from it, and a length of 0.920 m when a 2.17- kg mass hangs from it. a. What is the force constant of the spring? k : N! m b. What is the unloaded length of the spring? 1 : cm Add Work The loudness, L, of a sound {measured in decibels, dB) is inversely proportional to the square of the distance, d, from the source of the sound. (It is an inverse square relationship with distance.) When a person 3 meters from a jetski, it is 65 decibels loud. How loud is the jetski when the person is 15 meters away? (enter your answer as a number or decimal with 3 sig figs) dB (Hint, take end distance divided by begin distance to get the distance ratio. Then take Nd? to apply the inverse square law. ) Add Work
