Answer:
a. decrease by a factor of 3.
Explanation:
The intensity of light is inversely proportional to the square of distance.
I ∝1/d^2
or
I= k/d^2
where k is a constant
so, if d becomes 2d , I will be come I/4
Therefore, intensity will a. decrease by a factor of 3.
Answer:
Explanation:
For discharge of capacitor in RC circuit , the relation is as follows

V is voltage across the capacitor , V₀ is maximum voltage across capacitor , λ is time constant and t is the time after which the voltage is recorded. During discharge this will also be voltage across resistance .
Taking log on both sides
lnV = lnV₀ - 
Given equation
[lnV] = - .027 t + 2.5
Comparing these equation

λ = 37 s
time constant = 37 sec.
