hai điện tích q1=q, q2=-3q cách nhau một khoảng r. nếu điện tích q1 tác dụng lên điện tích q2 có độ lớn là f thì lực tác dụng q2 lên điện tích q1 có độ lớn là. Giải thích giúp mình chi tiết với ạ

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it

if the person is shown to have +90n, then ans is -10n.

if the person is shown to have -90n, then ans is +10n.

report!

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."

it is given that trillions of microbes make up to 1% to 3% of the body mass.

let's take average of this percentage: 2%

consider the average mass of the human body as 70 kg.

then, trillions of microbes would have mass  

therefore, 100 trillion micro-organisms would weigh:

this is an approximate value and could change depending on the mass of the human body and percentage of the microbes present in it.

average mass per microorganism =
