Which statements accurately relate radiation and health? Check all that apply.
A - Ionizing radiation produces ions that disrupt natural chemical reactions in the body.
B - Stochastic effects are associated with short-term, high-level exposure to radiation.
C - Cancer and DNA mutations are examples of non-stochastic effects.
D - A single X-ray delivers about 1/10 of the radiation exposure permitted for one person per year.
E - Lead shielding is an effective means of reducing radiation exposure.

Electroplating is a way to coat a complex metal object with a very thin (and hence inexpensive) layer of a precious metal, such as silver or gold. in essence the metal object is made the cathode of an electrolytic cell in which the precious metal cations are dissolved in aqueous solution. suppose a current of 480.ma is passed through an electroplating cell with an aqueous solution of agno3 in the cathode compartment for 46.0 seconds. calculate the mass of pure silver deposited on a metal object made into the cathode of the cell. round your answer to 3 significant digits. also, be sure your answer contains a unit symbol. ×10μ

The air that we breath is made mostly of which gaseous molecule

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.
