The faster a molecule is moving in the upper atmosphere, the more likely it is to escape Earth's gravity.
Given this fact, and your knowledge of rms speed, which of the following molecules can escape most easily from Earth's atmosphere if they are all at the same temperature?
The temperature in one part of a flame is 2,100 K. What is the rms velocity of the carbon dioxide molecules at this temperature? Give your answer as the number of meters per second.
mass of 1 mole of CO2 = 44.0 grams
1 mole contains 6.02 x 1023 molecules
the Boltzmann constant k = 1.38 x 10-23 J/K
The specific heat of a certain substance is 375 J/(kg°C). How much heat energy would you have to add to increase the temperature of 22 kg of this substance from 33°C up to 44°C in a number of Joules?

- Figure 8.14 shows a cube at rest and a small object heading toward it. (a) Describe the directions (angle 1) at which the small object can emerge after colliding elastically with the cube. How does 1 depend on b, the so-called impact parameter? Ignore any effects that might be due to rotation after the collision, and assume that the cube is much more massive than the small object. (b) Answer the same questions if the small object instead collides with a massive sphere.arrow_forward2. A projectile is shot from a launcher at an angle 0,, with an initial velocity magnitude vo, from a point even with a tabletop. The projectile hits an apple atop a child's noggin (see Figure 1). The apple is a height y above the tabletop, and a horizontal distance x from the launcher. Set this up as a formal problem, and solve for x. That is, determine an expression for x in terms of only v₁, 0, y and g. Actually, this is quite a long expression. So, if you want, you can determine an expression for x in terms of v., 0., and time t, and determine another expression for timet (in terms of v., 0.,y and g) that you will solve and then substitute the value of t into the expression for x. Your final equation(s) will be called Equation 3 (and Equation 4).arrow_forwardDraw a phase portrait for an oscillating, damped spring.arrow_forward
