Humans impact the environment, which can, in turn, have an effect on human health. Pollution is caused by human activity, and it also affects human health. Air pollution can cause respiratory problems and water pollution can lead to digestive problems. As human health is affected by these issues, concern increases and policies are enacted that address the causes of the issues. These policies do benefit the environment, but are, in part, brought about by concerns over human health.
The electromagnetic waves with an energy of are likely X-rays.
The energy of an electromagnetic wave is related to its frequency and wavelength by the equation:
E = hf = hc/λ
where:
E = energy of the electromagnetic wave
h = Planck's constant ()
f = frequency of the electromagnetic wave
c = speed of light ()
λ = wavelength of the electromagnetic wave
Solving for λ:
λ = hc/E =
λ ≈
This corresponds to a wavelength of about 44 nanometers, which falls in the range of X-rays. Therefore, the electromagnetic waves with an energy of are likely X-rays.

Answer;
the potential difference
The magnitude of the electric current is directly proportional to the potential difference of the electric field
Explanation;
An electric current results from the collective movement of free charges under the effect of an electric field. An electric field exists and can be observed in the space around a single charge or a number of charges.
Electric fields cause charges to move. It stands to reason that an electric field applied to some material will cause currents to flow in that material. In other words, the current density is directly proportional to the electric field. The constant of proportionality σ is called the material’s conductivity.
The Magnitude of the electric current is directly proportional to the voltage of the electric field.
B. The General Gas Law
C. Boyle's Law
D. The Law of Cubic Expansion
Answer:
(C) Boyle's law
Explanation:
According to Boyle's law when we kept the temperature as constant and is we decrease the pressure of the gas then the volume of the gas is increases it means that at pressure and volume are inversely proportional to each other when we take temperature as constant.
So for the given statement Boyle's law will be correct option
So option (c) will be correct option
