The given question is incomplete. The complete question is as follows.
For your senior project, you would like to build a cyclotron that will accelerate protons to 10% of the speed of light. The largest vacuum chamber you can find is 60 cm in diameter.
What magnetic field strength will you need?
Explanation:
Formula for the strength of magnetic field is as follows.
B = 
Here, m = mass of proton = 
kg
v = velocity = 10% of 
= 
m/s
q = charge of proton = 
r = radius = 
= 30 cm = 0.30 m (as 1 m = 100 cm)
Therefore, magnetic field will be calculated as follows.
B =
= 
= 
= 1.0437 T
Thus, we can conclude that magnetic field strength is 1.0437 T.
Answer:
Inverse proportion, greater
Explanation:
The relation between wavelength (λ) and frequency (ν) is given by
Where 
speed of light in vacuum.
We can see from this equation that wavelength and frequency are related inversely.
Now,
Where 'E' is energy of electromagnetic radiation and 'h' is Planck's constant.
We can see from this equation that greater frequency (ν) will give greater electromagnetic radiation (E). As they are directly proportional.
Hence,
When decreasing electromagnetic radiation there is a(n) Inverse proportion relationship between wavelength and frequency and the greater the frequency, the greater energy the electromagnetic radiation has
Greenhouse gases can cause Earth's atmosphere to trap more and more heat. This causes Earth to warm up. Using fossil fuels results in a rise of greenhouse gases.
