How does the spring constant of the smaller springs relate to that of the original spring? Choose the correct explanation.
A) The spring constant of each half will be half the spring constant of the original long spring since it will stretch twice as much under the same tension
B) The spring constant of each half will be twice the spring constant of the original long spring since it will stretch twice as much under the same tension.
C) The spring constant of each half will be twice the spring constant of the original long spring since it will stretch only half as much under the same tension.
D) The spring constant of each half will be half the spring constant of the original long spring since it will stretch only half as much under the same tension.

An air bubble of volume 20 cm³ is at the bottom of a lake 40 m deep, where the temperature is 4.0°c. the bubble rises to the surface, which is at a temperature of 20°c. take the temperature of the bubble’s air to be the same as that of the surrounding water. just as the bubble reaches the surface, what is its volume?

Air initially at 0.75 bar, 1000 k, and occupying a volume of 0.12 m^3 undergoes two processes. process 1-2: the air is compressed isothermally until the volume is halved. process 2-3: the air undergoes a constant pressure process until the volume is halved again. assume ideal gas behavior. a) determine the mass of the air, in kg. b) the work and the heat transfer for each of the two processes, in kj. (100 kj = 1 bar . m^3)
