An emission Ray has a frequency of 5.10 x10^14 Hz. Given that the speed of light is 2.998 x10^8 m/s, what is the wavelength of the Ray?

Answers

Answer 1

Answer: Speed of Light = frequency × wavelength
C = λ ν
∴ ν = C ÷ λ
ν = ( $2.998 * 10^(8) m/s )$ ÷ $(5.10 * 10^(14) Hz)$
= 5.87 × $10 ^(-7)$ m

How many grams of oxygen can be created when you heat 200g of sodium chlorate

Answers

The balanced chemical reaction is:

2NaClO3 9= 2NaCl + 3O2
We are given the amount of sodium chlorate to heat. This will be the starting point of our calculations.

200 g NaClO3 (1 mol / 106.44 g) ( 3 mol O2 / 2 mol NaClO3) (32 g O2 / 1 mol O2) = 90.19 g O2

Using less water is one way to practice watera. filtration.
b. distribution.
c. conservation.
d. irrigation.

Answers

Answer: Option (c) is the correct answer.

Explanation:

When we avoid wastage of water or overuse of then then it is known as conservation of water.

For example, turning off tap when bucket placed below it is filled with water means avoiding wastage of water.

Whereas over flow of water from the bucket is wastage of water.

Thus, we can conclude that using less water is one way to practice water conservation.

Using less water is one way to practice c. conservation. That would come in handy for a drought :D. Hope this helps and have a good day!
