La cabeza humana es (aproximadamente) una esfera conductora de aproximadamente 10cm de radio. ¿Cuál es su capacitancia? ¿Cuál será la carga si, mediante una maquina electrostática eleva el potencial de ella (y de su cuerpo) a 100 000 V?

i think it is 18

step-by-step explanation:

addition

step-by-step explanation:

3x-x+2=4 i think that's is the answer, and i hope it you

b) yes

step-by-step explanation:

let the statements be named as,

statement 1: if the power has been cut, then the refrigerator does not work.

statement 2: the refrigerator does not work.

conclusion: the power has been cut

now, 'law of detachment states that if we have the statements given as,

1. if p, then q.

2. p

then, we get the true statement or conclusion as q'.

thus, on comparing, we get that,

p: if the power has been cut.

q: the refrigerator does not work.

so, the argument is true by the law of detachment.
