<h2>Answer: Ion </h2>

An ion is an atom that is electrically charged by <u>gaining or losing one or more electrons. </u>

To understand it better:

An atom has a nucleus with electrons around it and has a neutral charge. When an electron is added or detached, this atom is electrically charged, that is, it ceases to have a neutral charge and becomes an <u>ion</u>.

In this sense, there are two types of ions:

-Anions: ions negatively charged, by the gain of electrons in the atom.

-Cations: ions positively charged, by the loss of electrons in the atom.

Sort out electric current as fundamental or derived unit.

Gemiola [76]

Answer:

electric current is derived unit.

Explanation:

According to the definition of electric current, it appears to be a derived quantity. Charge on the other hand seems more fundamental than electric current.

otez555 [7]

Answer:

The tangential speed of the ball is 11.213 m/s

Explanation:

The radius is equal:

$r=2.3*sin70=2.161m$ (ball rotates in a circle)

If the system is in equilibrium, the tension is:

$Tcos70=mg\\Tsin70=\frac{mv^{2} }{r}$

Replacing:

$\frac{mg}{cos70} sin70=\frac{mv^{2} }{r} \\Clearing-v:\\v=\sqrt{rgtan70}$

Replacing:

$v=\sqrt{2.161x^{2}*9.8*tan70 } =11.213m/s$

From the formula for Electric Power, P = IV, P = V²/R

So the 100W compared to the 50W.

From P = IV. From the equation there is a direct relationship between P and I. More Power P means more Current, I.

From P = V²/R. From the equation, there is an inverse relationship
between P and R. Therefore more P means less R.

So from these assertions, the answer is:

(1) less resistance and draws more current
