Answer:
Alternating
Explanation:
It is alternating because it is easy to distribute long distance.
Direct current is found in batteries and have large voltage drop over distance.
No. You cannot rule out the battery even after the open circuit voltage measurement. The open-circuit voltage may not have changed but the battery's internal resistance may have greatly increased.
Answer:0.061
Explanation:
Given
Temperature of soup
heat capacity of soup
Here Temperature of soup is constantly decreasing
suppose T is the temperature of soup at any instant
efficiency is given by
integrating From to
Now heat lost by soup is given by
Fraction of the total heat that is lost by the soup can be turned is given by
