Suppose that you put one air molecule on your desk, so it is in thermal equilibrium with the desk at 16.9°C. Suppose that there is no atmosphere to get in the way of this one molecule bouncing up and down on the desk. Calculate the typical height that the air molecule will be above your desk, so that Mgy ≈ kBT. (For simplicity, assume that the air molecule is diatomic nitrogen.) kB = 1.3807e-23

If angle "a" is 25°, angle "b" is: a) equal to angle c b) less than angle c c) greater than angle c

The ph is the a.independent variable b.the dependent variable c.control group

Suppose a force of 60 n is required to stretch and hold a spring 0.1 m from its equilibrium position. a. assuming the spring obeys hooke's law, find the spring constant k. b. how much work is required to compress the spring 0.5 m from its equilibrium position? c. how much work is required to stretch the spring 0.6 m from its equilibrium position? d. how much additional work is required to stretch the spring 0.1 m if it has already been stretched 0.1 m from its equilibrium? a. kequals 600
