Pick a car model (preferably the one you drive, but can also be any car of your dreams), and find its stopping distance at highway speeds (you can usually find this type of data online). Assuming that the car in front of you suddenly does a hard brake. For simplicity, assume that its braking performance is about the same as yours. Then also assume a reasonable amount of reaction time on your part (the time delay between seeing the brake lights lit up and applying your own brake). In order for you not to run into the car your are following, what's the closet distance you need to keep between the two cars

Picture a all traveling at a constant speed around the inside of a circular structure. is the ball accelerating? explain your answer

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

If the specific heat of a metal is 0.850 j/g °c, what is its atomic weight?
