How are neutron stars and white dwarfs similar?
What will be an ideal response?
They are both compact objects, with about the same mass. Both are supported by degenerate matter: white dwarfs by degenerate electrons, and neutron stars by degenerate neutrons.

An explosion of genetic diversity similar to that which occurred during the Cambrian Period hasn't happened recently, most likely because
A) evolution of life on Earth is no longer occurring B) such an explosion can occur only for simple organisms and not complex ones C) there are no more ecological niches available to allow this to happen D) of the widespread presence of efficient predators that make it much more difficult for entirely new organisms to appear

A 50-gram sample of dry ice (solid CO2) is placed in a 4-liter container. The system is sealed and allowed to reach room temperature (20°C). By approximately how much does the pressure inside the container increase when the dry ice turns to gas? (Ignore the initial volume of the sample.)
You throw a baseball straight up. Compare the sign of the work done by gravity while the ball goes up with the sign of the work done by gravity while it goes down
A) The work is positive on the way up and positive on the way down. B) The work is positive on the way up and negative on the way down. C) The work is negative on the way up and positive on the way down. D) The work is negative on the way up and on the way down because gravity is always downward.
