N) A rectangular piece of aluminum foil is 12.8 cm long and 4.20 cm wide. It has a mass of 0.319 g.
What is the thickness of the aluminum foil if the
density of aluminum is 2.70 g/cm'?

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current

warm front forms when a moist, warm air mass slides up and over a cold air mass. as the warm air mass rises, it condenses into a broad area of clouds. a warm front brings gentle rain or light snow, followed by warmer, milder weather.

hope i !
