The time constant is how long will the current decrease by 1/e. The numerical value of this is approximately equal to 0.37. Since we are looking at the decrease which is equal to 1 less than this value, the answer would be 0.63. Thus, the answer to this item is letter E.

E, 63% of the value. I forget the rationale behind it but I learnt that in engineering. 90% confident for that answer.

You see a total eclipse of the sun. Three Saros cycles later, you find yourself at the same location.

Nitella [24]

Answer:

Contemporary light microscopes are able to magnify objects up to about a thousand times. Since most cells are between 1 and 100 μm in diameter, they can be observed by light microscopy, as can some of the larger subcellular organelles, such as nuclei, chloroplasts, and mitochondria.

A cell is the smallest unit of a living thing. A living thing, whether made of one cell (like bacteria) or many cells (like a human), is called an organism. Thus, cells are the basic building blocks of all organisms.

Cells have many structures inside of them called organelles. These organelles are like the organs in a human and they help the cell stay alive. Each organelle has it's own specific function to help the cell survive. The nucleus of a eukaryotic cell directs the cell's activities and stores DNA.

If the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume. When this happens, the cell must divide into smaller cells with favorable surface area/volume ratios, or cease to function.

lightning strikes in the distance and six seconds later Thunder is heard how far away was the lightning strike
marshall27 [118]
The speed of sound really depends on the temperature and moisture in the air,
and the sound of the thunder doesn't necessarily travel straight from the lightning
to where you are.  So we can't say exactly. 

But if we use the nominal speed of 340 m/s, then 6 seconds means 2,040 meters,
or about 6,700 feet, or about 1.27 miles.
