Nitromethane CH3NO2) burns in air to produce significant amounts of heat. 2 CH3NO2(l) + 3/2 O2(g) --> 2 CO2(g) + 3 H2O(l) + N2(g). delta H^0 reaction = -1418 kJ How much heat is produced by the complete rection of 6.66kg of Nitromethane?
A 0.410kg block is attached to a horizontal spring that is at its equilibrium length, and whose force constant is 22.0N/m . The block rests on a frictionless surface. A 6.00×10^2kg wad of putty is thrown horizontally at block, hitting it with a s..

A square loop (edge = 9.4 cm) is comprised of 41 turns of copper wire. The square loop is placed in the plane of the page, What is the magnitude of the induced emf in the square loop
Two Styrofoam balls with the same mass m = 7.7 10-8 kg and the same positive charge Q are suspended from the same point by insulating threads of length L = 0.92 m. The separation of the balls is d = 0.027 m. What is the charge Q?
A metal sphere A has charge Q. Two other spheres, B and C, are identical to A except they have zero net charge. A touches B, then the two spheres are separated
A boat crosses the river from the south shore to the north shore by maintaining a constant velocity of 15.0 m/s due north relative to the water. Illustrate what is the velocity of the boat relative to shore?
make sure to label the graphs with units and values to indicate any critical points of the ball's motion.
Compute the average linear velocity of the discus
A race car has a mass of 718 kg. It starts from rest and travels 45.0 m in 3.0 s. The car is uniformly accelerated throughout the entire time. What net force is exerted on it.
A student wearing frictionless in-line skades on a horizontal surface is pushed by a friend with a constant force of 23.00N. How far should the student be pushed, starting from rest, so that her final kinetic energy is 283J.
