Answer:
Explanation:
From the question we are told that:
Number of battery
Voltage source
Lamp Power
Generally the equation for Resistance is mathematically given by
Therefore
Generally the equation for Current is mathematically given by
mass=5 kg
potential energy=6000j
height=?
Now
potential energy =m.g.h
or 6000=5*9.8*h
or 6000=49h
or 6000÷49=h
or h= 122.45m
V=1.5V
p=I×V
4.5=3×V
v=1.5
