The 15 g head of a bobble-head doll oscillates in SHM at a frequency of 4.0 Hz.

a. What is the spring constant of the spring on which the head is mounted?

b. suppose the head is pushed 2.0 cm against the spring, then released. What is the head's maximum speed as it oscillates?

c. the amplitude of the head's oscillations decreases to 0.5cm in 4.0s. What is the head's damping constant?

(science)study the following ocean currents map. an ocean currents map is shown. on the map the locations for san diego, california and savannah, georgia are marked. there is a looping current from the north past san diego and a looping current from the south near savannah which statement is most likely correct about the average temperatures in san diego, california as compared to savannah, georgia? it is higher in savannah because of the cool ocean currents from the south. it is higher in savannah because of the warm ocean currents from the north. it is lower in san diego because of the warm ocean currents from the south. it is lower in san diego because of the cool ocean currents from the north.

Could someone me find the answer to this problem.

Which of the choices below is one of the primary gases found in the atmosphere? a. helium b. carbon dioxide c. nitrogen d. argon
