Answer:

principle of contiguity

Explanation:

The Law of Contiguity states that after events occur together (in spatio-temporal proximity), the re-occurrence of just one of the event awakens the 'memory' of the others. It is employed in a great number of scientific theories of learning, memory, and knowledge.

BARSIC [14]

Answer:

The correct option is;

c. He conducted experiments with balls and inclined planes

Explanation:

The inclined plane experiment conducted by Galileo Galilei was one of his most important experiments.

The experiment consisted of a grooved board with which a small metal ball is rolled down in, so as to analyze the held Aristotelian ideas about motion.

In the experiment, the focus was on acceleration, a concept that the previously held ideas about motion

A spring with a spring constant of 4 N/m is stretched by Sarah's dog until extended by 2 m. How much elastic potential energy is
azamat

Hi there!

Recall the equation for spring potential energy:

PE = \frac{1}{2}kx^2

k = Spring constant (N/m)

x = extension of spring from equilibrium (m)

PE = Potential Energy (J)

Plug in the given values:

PE = \frac{1}{2}(4)(2^2) = \boxed{8 J}

Neko [114]

Answer:

Explanation:

Energy of radiation in eV = 1237.5/280 = 4.42 eV.

Work function = 2.65 eV.

Maximum kinetic energy = 4.42 - 2.65 = 1.77 eV.
