37) To convert the mechanical energy of running water into electrical energy, a runway is constructed using a hallow metallic pipe of uniform cross sectional area, and dam. As water falls through a length, and a force , F builds up to turn turbines for the generation. The force F is found to be related to S,I and v by f- = B/s + kv where B and k are constants. Which of the following statements is/are true about the give equations? 1. The equation expresses the idea of energy conservation. 2. the units of B and K are respectively kgm2s2.

37) To convert the mechanical energy of running water into electrical energy, a runway is constructed
using a hallow metallic pipe of uniform cross sectional area, and dam. As water falls through a length,
and a force , F builds up to turn turbines for the generation. The force F is found to be related to S,I
and v by f- = B/s + kv² where B and k are constants. Which of the following statements is/are true
about the give equations?
1. The equation expresses the idea of energy conservation.
2. the units of B and K are respectively kgm?s?.
3. the units of the terms B/s and kv² are the same.
