Matter behaving like a wave rather than like a particle is best illustrated by which phenomenon?

Answers

The photoelectric effect is about electrons being ejected from metals when light is shined on metals. The electrons do not behave like waves in the photoelectric effect. Black body radiation is all about the radiation emitted by warm bodies and not about those bodies behaving like waves. The emission spectra of atoms is all about what light is given off by atoms when electrons in those atoms jump down to lower energy levels from higher levels. That also has nothing to do with matter behaving as a wave. Interference is classically defined as the generation of a new wave with an amplitude modulated according to the waves that interfere to form that new wave. Note its emphasis on the wave part.

Answer:

Cells are the basic building blocks of all living things. The human body is composed of trillions of cells. They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions.

Explanation:

As a tile falls from the roof of a building to the ground its momentum is conserved.

Answers

No it isn't.
Gravity does work on the tile, causing its momentum
and its kinetic energy to increase.

Gravity works on tiles.

Further Explanation

Gravity or gravity is the attraction that occurs between all particles that have mass in the universe. Sun's gravity causes celestial bodies to be in their respective orbits around the sun. Modern physics describes gravity using Einstein's Theory of General Relativity, but Newton's simpler universal law of gravity is a fairly accurate estimate in many cases.

For example, the earth which has a very large mass produces a very large gravitational force to attract objects around it, including living things, and objects that exist on earth. This gravitational force also attracts objects in space, such as the moon, meteors, and other celestial bodies, including man-made satellites.

Kinetic energy or motion energy (also called kinetic energy) is the energy possessed by an object because of its motion.

The kinetic energy of an object is defined as the effort needed to move an object with a certain mass from rest to a certain speed.

The kinetic energy of an object is equal to the amount of effort required to express its speed and rotation, starting from the others.

Modern research in the theory of gravity began with the work of Galileo Galilei in the late 16th century and early 17th century. With the results of his experiments dropping the ball from the Tower of Pisa, and then also measuring the ball sliding through the slope, Galileo showed that the magnitude of gravitational acceleration was the same for all objects. This is a big advance from Aristotle's earlier belief that heavier objects have greater gravitational acceleration.
