The age of the universe in seconds
Marianna [84]

Answer:

4.351968e+17 seconds

Explanation:

So I googled age of the universe and it says 13.8 billion years.

you'll have to do some conversions:

in one year, there are 365 days. in one day, there are 24 hours. in one hour, there are 3600 seconds.

\frac{1 year}{365 days} x \frac{1 day}{24 hours} x \frac{1 hour}{3600 seconds}

so you have to add in the current age of the universe to that equation:

\frac{x seconds}{13.8 bil years} x \frac{1 year}{365 days} x \frac{1 day}{24 hours} x \frac{1 hour}{3600 seconds}

arranged so that the proper "units" will read as "x seconds" at the end of the equation.

then you do the math to find x:

13.8 billion x 365 x 24 x 3600 = 4.351968e+17 seconds.

which would be 435,196,800,000,000,000 seconds

Hope this helps :)

gulaghasi [49]

Answer:

The current would be 0.12A

Explanation:

Well, the formula for electric current is

i=\frac{q}{t}

where i is current, q is charge and t is time. Then we have to calculate the charge. If we know that the charge of a proton is 1.6*10^{-19} C, then we calculate the charge of 1500 protons as it follows:

q=1500*1.6*10^{-19} C\\q=2.4*10^{-16} C

So the current for each square meter of Earth's surface is

i=\frac{2.4*10^{-16} C}{1s} \\i=2.4*10^{-16} A

Finally, knowing the surface of the Earth is 510065284702000 m^{2}, we can calculate the total current i_{t}

i_{t}= 2.4*10^{-16} A*510065284702000\\i_{t}=0.12A
