A cylindrical aluminum wire of diameter d=0.9 mm runs electric current I=2.32 A. Find the drift velocity vd of conduction electrons corresponding to this current: vd= mm/s. What is the strength E of the electric field in the wire that causes this current?: E= V/m. To make things certain, let us use aluminum's mass density of 2.7 g/cm3 and resistivity = 2.82 10-8 Ω·m. The atomic mass of aluminum is 4.48 10-26 kg. You can assume that each atom supplies one conduction electron.

Ihave a density of 1.61g/cm^3 and a mass of 28g. find the missing value

Sasha has just gotten a new job in a nearby city. after comparison shopping, she found that renting a nice two-bedroom apartment would cost around $800 per month. her utilities would cost about $150 per month. sasha has enough money saved for a down payment, and she found that she can buy a three-bedroom house or condo with a mortgage payment of $1,000 per month, including taxes and homeowner's insurance. her utilities would cost about $200 per month. what is the advantage of buying the house over renting the apartment?
