Answer:
Microwaves are a type of wave that are sandwiched between radio waves and infrared radiation on the electromagnetic spectrum. In the case of microwave ovens, the commonly used wave frequency is roughly 2,450 megahertz.
Given :
Potential ,
Uniform magnetic field , B = 0.02 T .
Mass of proton , .
Charge on proton , .
Also , velocity of proton is perpendicular to magnetic field .
To Find :
The radius of the proton's resulting orbit .
Solution :
Now , when velocity is perpendicular to magnetic field radius of orbit is given by :
Putting all given values above :
Therefore , radius of orbit is 183.33 m .
Hence , this is the required solution .

I took the test and got this correct, hope this helps
Explanation:
Earth's atmosphere is made up of a combination of gases. The major components of nitrogen, oxygen, and argon remain constant over time and space, while trace components like CO2 and water vapor vary considerably over both space and time.
Answer:
I₂ = 25 W / m²
Explanation:
Intensity is defined as the relationship between power and area
I = P / A
the power emitted by the sun is constant
P = I A
for the two points of interest
I₁ A₁ = I₂ A₂
energy is distributed on the surface of a sphere
A = 4π R²
I₁ R₁² = I₂ R₂²
I₂ =
let's calculate
I₂ =
I₂ = 25 W / m²
