Answer:
B. Voltage
Explanation:
Ohm's law: current times resistance equals voltage.
V = IR
as the public need for preventing injuries and deaths from car crashes became known,laws were enacted to mandate the inclusion of seatbelts in almost all passengers vehicles
Answer:

Given:
efficiency of the turbine,
= 65% = 0.65
available gross head,
= 45 m
head loss,
= 5 m
Discharge, Q = 
Solution:
The nozzle is 100% (say)
Available power at the inlet of the turbine,
is given by:
(1)
where
= density of water = 997 
acceleration due to gravity, g = 
Using eqn (1):

Also, efficency,
is given by:
