Um corpo tem uma carga igual a -32. 10-6 C. Quantos elétrons há em excesso nele?

a)20x10^13

b)-20x10^13

c)2,0x10^13

d)-2,0x10^13

e)NDA

a) 2*10^14 electrons

Explanation:

To find the amount of electrons you take into account that:

by replacing this values in the factor C of the charge given by the exercise you obtain:

= 2*10*10^13 =20*10^13 electrons (you take the absolute value)

hence, the total number of electrons in a charge of 32*10^-6 C is 2*10^13 electrons

depends on what you mean by "group." for order, it would be coleoptera (beetles). for class, it would be insecta (insects). for phylum, it would be the arthropoda (animals with jointed exoskeletons).

i think its c if i'm wrong
