159.69g⋅5=798.45g that is the correct answer
m = pVol
p : copper density
Vol: volume
Vol = Al
A: area
L: length
m = p * A * L
L = m/p*A
To find the total resistance
Rtotal = R per Km * L/1000
Actually I think the question is missing the copper density.
Answer:
In 70s we were not much familiar with coca cola. Pepsi were sold in liter and milk is traditionally sold locally sold in gallon.
Explanation:
Sarah Brew said that unlike to the global brand like coca cola, Pepsi are sold at global level but milk is sold at local level follow the local custom measurement. If we look back in history, the milkman sold milk door to door in the form of quartz and the gallons. Same things consumers expected from seller.
These are two ways that play a role in grocery shopping. That's why the congress make a product list in form of liter and metric and traditional inches , gallons, pounds, milk etc.
