47. Calculate Final Temperature 200 g of water in a glass is at 10.0°C when an ice
cube is placed in the glass. What is the tem-
perature of the water after it has transferred
4,200 J of thermal energy to the ice cube?

The electronic structure or chlorine is 2.8.7 what is the electronic structure of fluorine?

Asap and show ! a 14 kg rock starting from rest free falls through a distance of 5.0 m with no air resistance. find the momentum change of the rock caused by its fall and the resulting change in the magnitude of earths velocity. earth mass is 6.0 * 10^24 kg. show your work assuming the rock earth system is closed.

Suppose a wheel with a tire mounted on it is rotating at the constant rate of 2.15 times a second. a tack is stuck in the tire at a distance of 0.373 m from the rotation axis. noting that for every rotation the tack travels one circumference (a) find the tack's tangential speed. (b) what is the tacks radial acceleration?
