The color of many ceramic glazes comes from cadmium compounds. If a piece of cadmium with mass 65.6 g and a temperature of 100.0°C is dropped into 25.0 cm3 of water at 23.0°C, what will be the final temperature of the system? The density of water at 23°C is 0.9978 g/mL , the specific heat capacity of water is 4.184 J g-1 K-1 , and the specific heat capacity of cadmium is 0.2311 J g-1 K-1 .
The solar wind is a thin, hot gas given off by the sun. Charged particles in this gas enter the magnetic field of the earth and can experience a magnetic force, calculate the radius of the circular path on which the particle would move if it were a..
At t = 0, a particle leaves the origin with a velocity of 12 m/s in the positive x direction and moves in the xy plane with a constant acceleration of (-2.0i+4j) . At the instant the y coordinate of the particle is 18 m, illustrate what is the x ..
Physics two skaters with masses of 65 kg and 45 kg, respectively stand 8.0 m apart each holding one end of a rope. If they pull themslevles along the the rope until they meet explain how far does each skater travel?
A -3.07 ?C charge is placed at the center of a conducting spherical shell, and a total charge of +6.70 ?C is placed on the shell itself. Calculate the total charge on the outer surface of the conductor.
A number of people are riding in a hot-air balloon. The combined mass of the people and balloon is 281 kg. The balloon is motionless in the air, since the downward-acting weight of the people and balloon is balanced by an upward-acting 'buoyant' f..

The spring is aligned with the plane and has a spring constant of 133 N/m. Explain how much does the spring stretch?
The coefficient of kinetic friction is 0.400. Illustrate what should be the magnitude of P, so that the net work done by it and the kinetic frictional force is zero?
Suppose a 61 kg boy and a 43 kg girl use a mass less rope in a tug-of-war on an icy, resistance-free surface. If the acceleration of the girl toward the boy is 3.0 m/s2, find the magnitude of the acceleration of the boy toward the girl.
If a car traveling at 55 km/h will skid 24 m while its brakes lock, how far will it skid if it is traveling at 130 km/h when its brakes lock.
