Explanation:

The energy of electromagnetic radiation is given by :

E=h\nu

Where, h is the Planck's constant

(a) A gamma ray, \nu = 1.64\times 10^{20}\ Hz

Energy,

E=6.63\times 10^{-34}\times 1.64\times 10^{20}\\E=1.08\times 10^{-13}\ J

(b) A microwave, \nu = 4.95\times 10^{10}\ Hz

Energy,

E=6.63\times 10^{-34}\times 4.95\times 10^{10}\\E=3.28\times 10^{-23}\ J

(c) A AM radio wave, \nu = 2\times 10^{6}\ Hz

Energy,

E=6.63\times 10^{-34}\times 2\times 10^{6}\\E=1.32\times 10^{-27}\ J

Therefore, this is the required solution.

3. The temperature of a fixed mass of gas in a rigid container is decreased from 127.00 degrees
Sonbull [250]

Answer:

750mmHg

Explanation:

The following data were obtained from the question:

T1 = 127°C = 127 +273 = 400K

T2 = 27°C = 27 +273 = 300K

P1 = 1000mmHg

P2 =?

P1/T1 = P2/T2

1000/400 = P2 /300

Cross multiply

400 x P2 = 1000 x 300

Divide both side by 400

P2 = (1000 x 300)/400

P2 = 750mmHg

Therefore, the new pressure after cooling is 750mmHg

Qué clase de alimentos podemos encontrar que contengan oligoelementos como Cromo (Cr), Litio (Li), Selenio (Se), Manganeso (Mn),
Slav-nsk [51]

Answer: There are many foods who have trace elements like seafood, legume, vegetables, tomatoes, bananas, eggs, fishes, meat.

Their five mainly functions are accept or receive electrons in redox reactions, act like cathalytic centers which are necessaries to live, control biologics process like the hormon activation and gen expression, provide stability, 3d structures in important molecules.

Explanation: Trace elements participate in redox reactions because they have acid-base components which alkalize o acidify the way, protecting the organism from free radicals.

Biological sources which are controlled by trace elements are:

  • assimilation of ATP
  • methabolic sources relationed with insuline
  • oxygen transport in the organism
  • stomach acid formation
  • 3d structures from important moleculess are mantained by balance of electrons which make up the atoms from the molecule.

A sample of oxygen gas occupies 3.60 liters at a pressure of 1.00 atm. If temperature is held constant, what will be the volume
evablogger [386]
P1V1=P2V2
(1.00atm)(3.60L)=(2.50atm)V
3.60=(2.50atm)V
3.60/2.50=V
1.44L=V
