Is it a must that a nucleus must have opposite nature with the electron

1 answer:

7 0

Generally, the nucleus of an atom has a positive CHARGE because of the protons (not sure what you mean by nature) which helps attract the electrons the nucleus but it stays within it's electron cloud.

It cannot have the same charges as electrons (being negative) as the electrons would be repelled and the atom would lose it's structure.

I hope this answers the question.

What is the mechanical advantage of the wheel and axle shown below?

BigorU [14]

The correct answer is A. 32.5

Mechanical advantage is the ratio of force that is input into a machine to the force output.

Mechanical advantage of a wheel and axle is calculated by dividing the radius of the wheel by that of the axle.

MA=R/r where R is the radius of the wheel and r is the radius of the axle.

Substituting for the values in the question gives:

MA=26cm/0.8cm

=32.5

Explanation:

The package in relation to the point where it was released falls a certain distance that is calculated by applying the horizontal motion formulas , as the horizontal speed of the plane and the height above the ground are known, the time that It takes the package to reach its destination and then the horizontal distance (x) is calculated from where it was dropped, as follows:

$V_{ox}=v_x = 40 \ m/s$
