2. Calculate the energy in joules of a photon whose frequency is 7.55×1014 Hz.

Mathematics

The energy of a photon is given by
E = h × v

where:
E is the energy in joules/photon
'h' is the constant 6.63 × 10⁻³⁴
'v' is the frequency 7.55 × 10¹⁴

Substitute 'h' and 'v' into the formula we have

E = (6.63×10⁻³⁴) × (7.55×10¹⁴)
E = (6.63×7.55) × (10⁻³⁴ × 10¹⁴)
E = 50.0565 × 10⁽⁻³⁴⁺¹⁴⁾
E = 50 × 10⁻²⁰ joules/photon

Convert 12080 gallons per month into liters per hour
Anastaziya [24]

In this question , we have to convert 12080 gallons per month to liters per hour .

There are 3.78541 liters in 1 gallons , and there are 30 days in a month, and 24 hours in a day .

So to convert 12080 gallons per month, we have to multiply 12080 by 3.78541 and divide the result by the product of 30 and 24. THat is

12080 gallons per month = \frac{12080*3.78541}{24*30} liters / hour

= \frac{45727.75280}{720} liters/ hour = 63.51 liters/hour

milo is talking to his sister lisa about factors. he said he thinks that any even number always has more factors than any odd nu
UkoKoshka [18]

Answer:

I agree with Lisa

Step-by-step explanation:

* Lets explain the meaning of the factors of a number

- Factors are the numbers you multiply to get another number

- Ex: factors of 12 are 1 , 2 , 3 , 4 , 6 , 12 because

 1 × 12 = 12 , 2 × 6 = 12 , 3 × 4 = 12

- 1 is a factor every number

- The number is a factor of itself

* Lets solve the problem

- Milo said he thinks that any even number always has more

 factors than any odd number

- Lisa said she doesn't agree with him

* Lets take some examples for even and odd number to prove who

 is right

- We will chose numbers between 1 and 22

# Even numbers: 2 , 4 , 14 , 18

# Odd numbers: 3 , 9 , 15 , 21

∵ The factors of 2 are 1 , 2

∴ 2 has 2 factors

∵ The factors of 4 are 1 , 2 , 4

∴ 4 has 3 factors

∵ The factors of 14 are 1 , 2 , 7 , 14

∴ 14 has 4 factors

∵ The factors of 18 are 1 , 2 , 3 , 6 , 9 , 18

∴ 18 has 6 factors

∵ The factors of 3 are 1 and 3

∴ 3 has 2 factors

∵ The factors of 9 are 1 , 3 , 9

∴ 9 has 3 factors

∵ The factors of 15 are 1 , 3 , 5 , 15

∴ 15 has 4 factors

∵ The factors of 21 are 1 , 3 , 7 , 21

∴ 21 has 4 factors

∵ The number of the factors of the even numbers are 2 , 3 , 4 , 6

∵ The number of the factors of the odd numbers are 2 , 3 , 4

∴ The Factors of even numbers and odd numbers are equal

  like 2 and 3 , 4 and 9 , 14 and 15

 <em>OR</em>

  The factors of even number greater than the factors of the odd

  number like 18 the number of the factors of 18 is greater than the

  number of the factors of all odd numbers above

∴ <em>Not always that any even number has more factors than any odd</em>

<em>   number</em>

∴ I agree with Lisa
