Answer:
A. He sent a cathode ray between electrically charged metal plates
Answer:
in a liquid, particles will flow or glide over one another, but stay toward the bottom of the container.
Explanation:
the attractive forces between particles are strong enough to hold a specific volume but not strong enough to keep the molecules sliding over each other.
The answer is "<span>An atomic nucleus is positively charged because it is composed of protons". An atomic nucleus actually contains nucleons which are made up of both protons and neutrons. Since neutrons are neutral or have no charge, the charge of an atomic nucleus mainly relies on the positive charge of the protons.</span>
Light as a wave
- Young's Double Slit Experiment.
- Davisson-Germer Experiment
Light as a particle
- Einsteins Photoelectric Effect Phenomenon
- Diffraction Phenomenon of Particles
<h2>Define the following terms:-</h2><h3>
1)Photoelectric Effect</h3>
Electrons are released when a material is exposed to electromagnetic radiation, such as light, and this is known as the photoelectric effect. These electrons are referred to as photoelectrons.
<h3>
2)Diffraction </h3>
When a wave hits a wall or an opening, several phenomena known as diffraction take place. It is described as the interference or bending of waves through an aperture into the region of the geometric shadow cast by the obstruction or aperture.
<h3>3)
Davisson-Germer Experiment</h3>
In the Davisson-Germer experiment, conducted by Clinton Davisson and Lester Germer between 1923 and 1927 at Western Electric (later Bell Labs), electrons scattered by a nickel-metal crystal's surface showed a diffraction pattern. This was an experimental turning point in the development of quantum mechanics and supported the wave-particle duality concept first put forth by Louis de Broglie in 1924.
<h3>4)
Young's Double Slit Experiment.</h3>
One of the most significant physics experiments was Young's Double Slit experiment. Thomas Young directed it in 1801. Despite the fact that Huygens' experiment had demonstrated that light has a wave character, the light at the time was still thought of as a beam of particles due to Newton's renown.

Hello! Charchar here!
Answer:
has an even shorter half-life. is around a hundred times higher. Rocks from the Earth's crust have isotope ratios varying by as much as a factor of ten; this is used in geology to investigate the origin of rocks and the composition of the Earth's mantle.
