A secondary pollutant is one that is not directly emitted but rather forms when primary pollutants react in the atmosphere. Among the options provided, sulfuric acid is a secondary pollutant. Correct option is D.
In the context of environmental science, a secondary pollutant is a type of pollutant that is not directly emitted. Instead, secondary pollutants are formed when primary pollutants undergo chemical reactions in the atmosphere. Among the options provided, option D) sulfuric acid is a secondary pollutant. The others - sulfur dioxide, radon and carbon monoxide - are primary pollutants, as they're emitted in this form from a source.

Select one:
a. Wave A and Wave B travel through Earth's interior.
b. Wave A and Wave B are absorbed by liquid medium.
c. Wave A and Wave C are absorbed by liquid medium.
On a seismogram, the first recorded waves are the P type, followed by the S type and, finally, the surface waves. Option A) A and B travel through Earth's interior.
Note: the question was answered according to the attached image. Look at the seismogram and the explanation, and if your image differs from this one, apply the same reasoning to answer the question.
When rocks break during plate movements, they generate waves that propagate, moving inside the Earth and on its surface. These are the seismic waves.
There are three types of waves,
P waves are the fastest in moving and can be transmitted through different materials, liquid or solid.
S wavesare slower and can not be transmitted through liquid masses.
Surface waves are the slowest ones.
Due to the difference in the speed, the first recorded waves on a seismograph during an earthquake are the P waves, followed by the S waves, and finally, the surface waves.
The difference in waves' speed is used to determine the location of the earthquake focus and the structures of Earth.
As waves move through different materials, they change their speed. This change leads scientists to know what type of masses they are going through.
Following the waves from earthquake focus and recording their travel speed is helpful to determine the structures of Earth's interior.
The provided seismogram shows,
A- P waves ⇒ Transmitted in the interior of the Earth ⇒ first ones to be recorded. They are absorbed by liquid and solid medium.
B- S waves ⇒ Transmitted in the interior of the Earth ⇒ second ones to be recorded. They are absorbed by solid medium.
C- Surface waves ⇒ Transmitted in the syperficial layers of the Earth ⇒ last ones to be recorded. They are the slowest ones.
According to this information, we can assume that the correct option is a. Wave A and Wave B travel through Earth's interior.

(2) –2 (4) +17
The charge of the nucleus in an atom of oxygen is +8. The correct option is 3.
The charge is negative or positive or neutral charges present on the substance or molecule. The charges are produced by the gaining or losing of electrons.
The charges tell the tendency of the atom or molecule of gaining or losing of the atom.
Thus, the correct option is 3, +8.
