A 200 g air-track glider is attached to a spring. The glider is pushed in 10 cm and released. A student with a stopwatch finds that 10 oscillations take 12.0 s. What is the spring constant?

28. evolution

29. environment, survive, offspring  

explanation:

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.

hi there!

out of the two, (b) precision would be more reasonable.   however, both a and b could be pretty reasonable.
