Brewed coffee is often too hot to drink right away. You can cool it with an ice cube, but this dilutes it. Or you can buy a device that will cool your coffee without dilution - a 270g aluminum cylinder that you take from your freezer and place in a mug of hot coffee. If the cylinder is cooled to -20 C, a typical freezer temperature, and then dropped into a large cup of coffee (essentially water, with a mass of 500 g at 85 C, what is the final temperature of the coffee?
An 8-g bullet is fired into a 170 g block that is initially at rest at the edge of a table of 1m height. The bullet remains in the block, and after the impact the block lands d = 2.10 m from the bottom of the table. Determine out the initial speed..
The specific heat of water is 4186 J/kg•K. The latent heat of fusion is 333 kJ/kg. The density of water is 1.0 g/cm.
The spring stretches 5.0 cm from its previous equilibrium position toward the two spheres. Calculate the spring constant.
If the electric field in an EM wave in free space has a peak magnitude of 7.5*10^-5 v/m, what is the peak magnitude of the magnetic field strength
The emissivity of her skin is 0.750 and its surface area is 1.30 m2. How much time would it take for her to emit a net radiant energy from her body that is equal to energy contained in this dessert.
assume the coefficient of kinetic friction between m_{rm A} and the plane in the figure is mu_k = 0.15, and that m_{rm{A}} = m_{rm{B}} = 2.7{rm{ kg}}. What smallest value of mu _{rm{k}} will keep the system from accelerating.
