The answer is 10 because you multiply 5.2=10 by using the formula
A.
Explanation:
Probably, if the sun was too close to the center of the galaxy, the solar system would experience chaos, such as a high frequency of collisions with other planets and stars, due to the enormous pull of the super black hole at the center of the MilkyWay Galaxy causing celestial objects to spin at very high speeds at its horizon – including bending light.
The position is postulated as the <u>Galactic habitable zone.</u>
Answer:
2NaBr + Ca(OH)2 ––> CaBr2 + 2NaOH
The term sulfate is used in chemistry to denote a salt of sulfuric acid. ... This is the sulfate type which can be found in many cleaning and hygiene products including shampoos. The main reasons why it is added to shampoos are because this sulfate produces foam and is a powerful detergent.
<u>Answer:</u> The speed of the electron is
<u>Explanation:</u>
To calculate the speed of electron for given wavelength, we use the equation given by De-Broglie's, which is:
where,
= De-Broglie's wavelength =
h = Planck's constant =
m = mass of the electron =
v = speed of the electron = ?
Putting values in above equation, we get:
Hence, the speed of the electron is
