As a student in a physics lab, you are asked to classify two springs. Right away you notice some differences. The first spring, spring 1, is very easy to compress and pliable. The second spring, spring 2, is stiffer and more difficult to deform. What qualitative statement can you make about their spring constants?
A. No inference can be made, the student needs to take a measurement.
B. The spring constant of spring 1 is larger than spring 2.
C. The spring constant of spring 2 is larger than spring 1.
D. The spring constants are the same because spring 1 has more displacement, while spring 2 requires more force.

If a refrigerator is a heat pump that follows the first law of thermodynamics, how much heat was removed from food inside of the refrigerator if it released 380j of energy to the room?

Simon is writing a story about an astronaut whose spacecraft has been boarded by space pirates. the astronaut has her lucky penny in her hand behind her back as the space pirates break into the control room. she has just locked the controls so that the ship is accelerating in the direction of the control room’s ceiling. simon wants the astronaut to use the penny to hit a button on the control panel to turn off the lights and escape. the button is located a short distance behind and below the astronaut’s hands. how should simon use the theory of relativity to describe what the astronaut must do in order to hit the button?
