Answer:

The amount of energy is directly proportional to the photon's electromagnetic frequency and thus, equivalently, is inversely proportional to the wavelength. The higher the photon's frequency, the higher its energy.

The voltage across a membrane forming a cell wall is 72.7 mV and the membrane is 9.22 nm thick. What is the magnitude of the ele

Blizzard [7]

Answer:

The magnitude of the electric field intensity is $E = 7.89 *10^{6} \ V/m$

Explanation:

From the question we are told that

The voltage is $\epsilon = 72.7 \ mV = 72.7 *10^{-3} V$

The thickness of the membrane is $t = 9.22 \ nm = 9.22 *10^{-9} \ m$

Generally the electric field intensity is mathematically represented as

$E = \frac{\epsilon }{t}$

substituting values

$E = \frac{72.7 *10^{-3} }{9.22 *10^{-9}}$

$E = 7.89 *10^{6} \ V/m$

GarryVolchara [31]

Answer:

Beryllium

Beryllium is an alkaline metallic element that is highly toxic. It is known for its sugary sweet taste and some of its common uses are in X-rays and fluorescent lights.

Beryllium : A very thorough and technical site about this mineral.

Chromite

Chromite is the ore of chromium and is a very hard metal, and diamond is the only thing harder. This hardness is what allows a chrome finish to take a high polish.

Chromite : This site talks about its history and characteristics.

Cobalt

Cobalt is famous for the incredible blue color it imparts to glass and pigment. It has been found in meteorites and is used in invisible ink. It is a brittle metal and resembles iron.

Cobalt : This site has photos, video, charts and physical and atomic descriptions.

Columbite-tantalite

Columbite-tantalite group is a mineral used widely in technology. Electronics, automotive systems and health products like the pacemaker need this mineral to operate. It is mined in Africa and has earned the name of Coltan over the last few years.

Columbite-tantalite : Information about its role in the world under the name 'Coltan'.

Copper

Copper is a common metal throughout the world. It is used for currency, jewelry, plumbing and to conduct electricity. It is a soft, orange-red metal.

Copper : This site talks about its properties, uses and makeup.

Regardless of their frequency, wavelength, or energy, all electromagnetic waves: A. travel only through the vacuum of space. B.

agasfer [191]

All electromagnetic waves travel at the same speed in a vacuum: 3.0 x 10^5 (300,000) kilometres per second. some electromagnetic waves are part of the visible light spectrum and some do emit harmful radiation, but certainly not all. they travel fine on earth without the vacuum of space too.
