In three separate trials and under the same conditions, you measure a gas's density to be 2.865 kg/m^3, 2.852 kg/m^3, and 2.860 kg/m^3. The actual density of the gas is3.214 kg/m^3. Evaluate the precision and accuracy of your measurement.

Explanation:

please follow me

yes it is balanced

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
