Compute the quantum volume for an N2 molecule at room temperature, and argue that a gas of such molecules at atmospheric pressure can be treated using Boltzmann statistics. At about what temperature would quantum statistics become relevant for this system (keeping the density constant and pretending that the gas does not liquefy)?
A simple pendulum has a mass of 0.150 kg and a length of 1.00 m. It is displaced through an angle of 10.0° and then released. What is the maximum restoring force
Starting from a location with position vector r1,x = -16.5 m and r1,y = 22.7 m, a rabbit hops around for 11.3 seconds with average velocity vav,x =-2.27 m/s and vav,y = 1.47 m/s. Find the components of the position vector
Given that the nearest star is about 4 light years away, develop an estimate of the density of stars per cubic light year in our galaxy. estimate the number of stars in the milky way galaxy given that it's roughly a disk 100 000 light years across..
a boat has a mass of 6800 kg. its engines generate a drive force of 4100 n due west while the wind exerts a force of
A person is riding a bicycle, and its wheels have an angular velocity of 19.8 rad/s. Then, the brakes are applied and the bike is brought to a uniform stop. Through braking, the angular displacement of each wheel is 12.0revolutions.
The period of a pendulum is 0.215 s on Earth. The period of the same pendulum is found to be 0.467 s on planet X, whose mass is equal to that of Earth.
