In the lab, you looked at speed-time graphs to determine the acceleration of the cart for each of the three fan speeds.
What was the acceleration of the cart with Low fan speed?
What was the acceleration of the cart with Medium fan speed?
What was the acceleration of the cart with High fan speed?

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

Gordon is going for a run through the park, but it is cold outside. the low outside temperature could affect his personal safety.

Charge is distributed along the entire x-axis with uniform density λ. how much work does the electric field of this charge distribution do on an electron that moves along the y-axis from y = a to y = b? (use the following as necessary: a, b, ε0, λ, and q for the charge on an electron.)
