Answer:

Rutherford established the nuclear theory of the atom with his gold-foil experiment. When he shot a beam of alpha particles at a sheet of gold foil, a few of the particles were deflected. He concluded that a tiny, dense nucleus was causing the deflections.

Answer:

1. There are 7 categories:

Radio waves, microwaves, infrared heat waves, visible light spectrum, ultraviolet waves, x-rays, gamma rays

2. They are all electromagnetic radiation.

3. The amount of energy the photons within them have.

4. The longer the wavelength, the less energy. The shorter the wavelength, the more energy. They are inversely proportional.

5. As the wavelength increases, the smaller the frequency. The shorter the wavelength, the larger the frequency. They are inversely proportional. Also, wavelength is measured in meters and frequency is measured in hertz (cycles per second). They are two of the 3 ways EM radiation is expressed.

6/7 Reds have the least. Violets have the most.

8. Violet has the shortest. Red has the longest.

9. Ultra Violet B-Rays (UV-B) are the harmful rays that cause sunburn.

10. Microwaves are generally used for radar technology.

11/12 You are exposed to all of the categories of the electromagnetic spectrum everyday of every year. You just can't see/feel them all.

hope this helps! stay happy and healthy, friend! :))

What are the characteristics of a continental drift?
Eduardwww [97]

Continental drift was a theory that explained how continents shift position on Earth's surface. Set forth in 1912 by Alfred Wegener, a geophysicist and meteorologist, continental drift also explained why look-alike animal and plant fossils, and similar rock formations, are found on different continents.

Gallium has two naturally occurring isotopes with the following masses and natural abundances: Isotope Mass ( amu ) Abundance (%
ICE Princess25 [194]
The formula for determination of atomic mass given the mass of isotopes and relative abundance is:

Ar = ∑(mass * abundance) / 100
Ar = (68.92558 * 60.108 + 70.92470 * 39.892) / 100
Ar = 69.72306

The atomic mass of gallium is 69.72306 amu
