Maggie is trying to find out if the amount of sugar in a liquid affects the amount of time it takes to freeze
A good hypothesis is: The more sugar in the drink the longer it takes to freeze
Conclusion= she concludes that her hypothesis is correct as the unsweetened tea froze the fastest while the root beer took the longest time as it contained the most sugar
Nuclear energy is EXTREMELY ecofriendly, punching down any fossil fuels and even wind energy. It also is reliable, and has low emissions. However, nuclear energy is somewhat expensive and can go wrong, being dangerous to the environment and people. Along with this, uranium is finite and radioactive waste disposal is really bad.
Answer:

Explanation:
We know that the frequency of the nth harmonic is given by
, where
is the fundamental harmonic. Since we have the values of two consecutive frequencies, we can do:

Which for our values means (we do not need the value of <em>n</em>, that is, which harmonics are the frequencies given):

Now we turn to the formula for the vibration frequency of a string (for the fundamental harmonic):

So the tension is:

Which for our values is:

The frequency of a photon with an energy of 4.56 x 10⁻¹⁹ J is 6.88×10¹⁴ s⁻¹.
<h3>What is a frequency?</h3>
The number of waves that travel through a particular point in a given length of time is described by frequency. So, if a wave takes half a second to pass, the frequency is 2 per second.
Given that the energy of the photon is 4.56 x 10⁻¹⁹ J. Therefore, the frequency of the photon can be written as,

Hence, the frequency of a photon with an energy of 4.56 x 10⁻¹⁹ J is 6.88×10¹⁴ s⁻¹.
