Answer:
The resistance is 
Explanation:
From the question we are told that
The voltage rating of the headlamp is 
The voltage of the power system is 
The power rating of the headlamp is 
Generally the power which the resistor dissipates is mathematically represented as

=> 
=> 
Generally the resistance is



Answer:
5.522 m
Explanation:
Data provided:
Mass, m = 1.03 kg
spring constant, k = 861.1 N/m
Distance by which the spring is compressed, x = 0.36
Thus,
the energy stored in the spring = 
on substituting the values, we get
the energy stored in the spring = 
now,
by the conservation of energy, we have
Potential energy gained by the mass = Energy gained by the spring
or
mgh = 
where,
g is the acceleration due to the gravity
h is the maximum height reached by the mass before falling
on substituting the values in the above relation, we get
1.03 × 9.81 × h = 
or
h = 5.522 m
