Answer:
is weaker than the electromagnetic force
Explanation:
The weak force or weak nuclear force acts between elementary particles.
Weak nuclear force is important in the reaction speed of some nuclear reactions that occur in stars. It is also present at the origin of volcanic explosions.
The weak force is a short-range force, less than a billionth of a millimeter: 10-13mm. At a greater distance, the intensity of this force is already negligible.
If the weak force had a value of 1,
the electromagnetic force would have a value of 1,000
and the strong force would be worth 100,000,000,000
Although it is vastly weaker than the other two nuclear forces, the weak force is important in that it enables the Sun and stars to produce light and energy.
The weak force causes a type of radioactive decay called "beta decay." An example of beta decay is the decay of the neutron when it becomes 1 proton + 1 electron + 1 neutrino

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.
C^2=a^2+b^2
c^2=45^2+45^2
c^2=4050
c=63.64
c=64
The answer is D.
