Which statement best describes how an existing theory is often affected by the development of new technology?

an existing theory is thrown out and replaced with a completely new theory based on the new observations.
an existing theory is modified so that it can explain both the old and new observations.
an existing theory remains the same because a theory is a proven fact that is always true.
an existing theory is kept unchanged while a new theory is developed to explain the new observations.

An existing theory is modified so that it can explain both the old and new observations.

A theory is a well-confirmed explanation of a phenomenon, most of the time associated with scientific studies. It requires the use of a consistent scientific method, which includes observation and experimentation. A theory should be written in a way that allows for it to be proven wrong. Theories are often challenged when new evidence comes to light, and this is the main way in which science progresses. When this happens, theories are usually modified in a way that explains both past and present phenomena.

it is a bolivia your welcome

well, paralell is parallel. i am providing links to .

hope this !

a series circuit is one with all the loads in a row. there is only one path for the electricity to flow. if this circuit was a string of light bulbs, and one blew out, the remaining bulbs would turn off.

unlike in series circuits, a charge in a parallel circuit encounters a single voltage drop during its path through the external circuit. the current through a given branch can be predicted using the ohm's law equation and the voltage drop across the resistor and the resistance of the resistor.

a parallel circuit has certain characteristics and basic rules: a parallel circuit has two or more paths for current to flow through. voltage is the same across each component of the parallel circuit.
