If nitrogen which has an electronegativity of 2.0 bonds with hydrogen which has an electronegativity of 2.1 the bond between the two atoms will be classified as an
covalent bond 2.0 bonds

answer:

polar bonds

explanation:

'polar bonds usually consist of different atoms unequally sharing electrons.'

in physics zero. in muscle fatigue could be high

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.
