Answer:

Explanation:
From the question we are told that:
Water flow Rate 
Initial Temperature 
Final Temperature 
Let
Specific heat of water 
And


Generally the equation for Heat transfer rate of water
is mathematically given by
Heat transfer rate to water= mass flow rate* specific heat* change in temperature



Therefore


Answer:
c 45 feet from the fulcrum
Explanation:
The moment at the fulcrum must be the same for each car. If the distance is d, then the artist must have ...
(2100 lb)(30 ft) = (1400 lb)(d)
2100·30/1400 ft = d = 45 ft
The Volkswagen should be 45 ft from the fulcrum.
