Answer:A
Explanation:
In R-L circuit current is given by
![i=i_0\left [ 1-e^{\frac{-t}{L/R}}\right ]](https://tex.z-dn.net/?f=i%3Di_0%5Cleft%20%5B%201-e%5E%7B%5Cfrac%7B-t%7D%7BL%2FR%7D%7D%5Cright%20%5D)
where i=current at any time t
R=resistance
L=Inductance
at t=0 
approaches to 1
therefore ![i=i_0\left [ 1-1\right ]](https://tex.z-dn.net/?f=i%3Di_0%5Cleft%20%5B%201-1%5Cright%20%5D)
i=0
when t approaches to 
, approaches to zero
thus 
thus we can say that initially circuit act as broken wire with zero current
and it increases exponentially with time and act as ordinary connecting wire
They make sure the bridge is functional and safe before the add the

One must have at least two visual pigments to distinguish between wavelengths independent of light intensity.
A substance that converts light energy into electrical potentials is called a visual pigment.
The basic structure of pigment consists of the chromophore, a colored molecule, and a protein called rhodopsin.
There are three types of visual pigments: Scotopsin, rhodopsins, and photopsin.
Scotopsin pigments are associated with vision and operate in less bright light while photopsin operates in a brighter light.
However, visual pigments are very significant substances as they are associated with vision and play a vital role in detecting light.

Answer:
The US Environmental Protection Agency (EPA) sets limits for exposure to x-rays and gamma rays in part because it recognizes that this form of radiation can cause cancer.
Answer:
The mild climate enabled Romans to grow wheat, grapes, and olives. This abundance o food supported the people and allowed Rome to prosper. While the climate made year-long agriculture possible, Rome also had the advantage to be near water. The Tiber River helped the agricultural system to prosper
