Answer:
It is -1.602 x 10^-19 C, and the smallest unit of charge
Step-by-step explanation:
The charge on an electron is 
. The charge on electron is negative. The quantization of electric charge is :
q = ne
q is net charge
n is no of electrons
e is the electronic charge which is 
. Hence, the correct option is (b).
3 3/4 is the mixed number for the fraction 15/4
hope this helps you
AN = (1/2^N-1) A1 { in general AN= (r^N-1) A1
<span>A5 = (1/2^4) 40 = 40/16 = 0.5

So the answer to your question is 0.5
Best to write this problem as shown below:
<span>562.34
-64.89
----------- First, estimate the correct answer. It would be 562-65 = 497.
Must borrow from the tenths column, because 9 is greater than 4. We end up with 5 under the 4 and 9. We must borrow again to obtain the next digit:
12-8=4, so the result is now .45
11-4=7, so the result is now 7.45
55-6=9, so the result is now 97.45.
Finally, 4-0=4, so the final result is 497.45. Compare this to the estimate (497).
Here we've had to borrow 4 times.</span>
