Which phrase best describes wave motion

Answers

Answer 1

Answer: Hi!
I don't know your options, but i can describe the wave motion for you:

wave motion is energy transfer through space that proceeds in regular variations (such as vibration),- we say that it's an oscillation because of the regular variations. These variations have specific characteristics, such as frequency or length.

The internal energy of a material is determined by

Answers

Answer:

Explanation:

The internal energy of any material is calculated as the sum of kinetic and potential energy of randomly distributed molecules.

This energy depends on temperature as well, if the temperature will increase the randomness will also increase hence will be the internal energy.

If any work is done on the system, then also the internal energy of the system is increased.

The combined amount of kinetic and potential energy of its molecules

Aristotle, the ancient Greek philosopher, thought that heavy objects fall to Earth faster than lighter objects. How could Aristotle's hypothesis be supported or disproved?

Answers

Gravitational potential energy=mass of object x gravitational field strength on earth(9.8 usually rounded to 10) x the height the object is held at

Therefore if two objects were held at the same height, the object with more mass(the heavier object) will fall faster because it's gravitational potential energy is greater than that of the lighter object

3. During a race, a sprinter increases from 5.0 m/s to 7.5 m/s over a period of 1.25s. What is the sprinter’s average acceleration during this period?Also please try and explain
Please and Thank you

Answers

(7.5)-(5)
----------- = 2 m/s^2
(1.25-0)

Average acceleration is calculated using the equation V(f)-V(i) / t(f)-t(i). (Final velocity minus initial velocity divided by final time minus initial time)

All atoms of the same element must have the same number of

Answers

Explanation:

Atomic number is defined as the total number of protons present in an element.

Each element of the periodic table has different atomic number because each of them have different number of protons.

For example, atomic number of Na is 11, and atomic number of Ca is 20.

On the other hand, atomic mass is the sum of total number of protons and neutrons present in an atom.

For example, atomic mass of nitrogen is 14 that is, it contains 7 protons and 7 neutrons.

Thus, we can conclude that all atoms of the same element must have the same number of protons.

Answer: Protons

Explanation: The number of protons corresponds to the atomic number.

Choose the answer that explains the photoelectric effect.

Answers

Photoelectric effects occurs in metals. When light or electromagnetic radiation shines upon these metals, electrons jump or are emitted freely. These emitted electrons are therefore called photoelectrons. This phenomenon can be measured in electric currents. Photoelectric effect also denotes the wave-like property of light.

Answer:

Metallic plates emit electrons only when light of a certain minimum frequency shines on them.
