Answer: Resistance

Explanation:

The tendency of a material to oppose flow of charges through it is known as resistance. It is an opposing force that acts against the electric current. It depends on the resistivity of the material, its length and diameter. It also depends on the temperature. With increase in temperature, resistance increases.

$R = \frac{\rho l}{A}$

It is measured in Ohms (Ω)

At constant voltage,

$I \propto \frac{1}{R}$

Thus, more resistance leads to low current value.

The law of universal gravitation states that a gravitational force exists between all objects in the universe. This force is dir

Answer: D. it has been demonstrated to be without exception under certain stated conditions.

Explanation:

A Law is an affirmation (something established) based on repeated long-term observation of a phenomenon that has been studied and verified.

That is: A law is present in all known theories and therefore is considered universal. In addition, a law can not be refuted, nor changed, because its precepts have been proven through various studies.

Unlike theory, which is the set of rules and principles that describe and explain a particular phenomenon and is subject to changes as new evidence emerges that gives meaning to it.

Then, based on what is explained above, the law of universal gravitation is a statement that exists because it was rigorously tested and verified, therefore it can not be refuted.
