A 15.00 L sample of Helium gas has a mass of .002 kg. What is the density of this sample? Your answer should be expressed in proper
scientific notation. Please show your work to receive credit.

Explanation:

Hello there!

In this case, according to the given information, it turns out possible for us to calculate the required density by knowing it is calculated by dividing mass over volume:

Therefore, we plug in the given kilograms and liters to obtain:

Which shows the proper scientific notation.

Regards!

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
