A cloud mass moving across the ocean at an altitude of 2000 m encounters a coastal mountain range. As it rises to a height of 3500 m to pass over the mountains, it undergoes an adiabatic expansion. Th
Given 2.50mol of an ideal gas with CV =12.47J?mol?1?K?1 is expanded adiabatically against a constant external pressure of 1.00 bar. The initial temperature and pressure of the gas are 325 K and2.50 ba
In a laboratory experiment, one end of a horizontal string is tied to a support while the other end passes over a frictionless pulley and is tied to a 1.4 kg {\rm kg} sphere. Students determine the fr
Two frisky grasshoppers collide in midair at the top of their respective trajectories and grab onto each other, holding tight thereafter. One is a robust beast of mass m1 initially moving south at a v

A 1000 MW fission reactor consume half of its fuel in 5 years. How much did it contain initially? Assume that the reactor operates 80% of the time, that all the energy generates arises from the fissio
Biologists think that some spiders "tune" strands of their web to give enhanced response at frequencies corresponding to those at which desirable prey might struggle. Orb spider web silk has a typical
When mass M is tied to the bottom of a long, thin wire suspended from the ceiling, the wire's second-harmonic frequency is 150Hz . Adding an additional 1.5kg to the hanging mass increases the second-h
The potential energy of two atoms in a molecule can be approximated by the Morse function:U(r)=A[((e^((R-r)/s)-1)^2 )-1)] where r is the distance between the two atoms and A, R and S are positive
