When light waves pass through solids, the speed of the wave ___________.
remains the same
decreases
increases
It woukd decrease.
I am sure its correct you can trust me becuase I took the test.
Answer:
The speed of the wave decreases.
Explanation:
When light waves do pass through a medium, any solid, liquid, or gas, the speed of the waves actually decreases. Solids are more dense than liquids, so they decrease the speed of light even more.

How does transfer of infrared energy relate to weather and climate conditions on Earth?
Answer:
Convection is the transfer of heat energy in a fluid. Air in the atmosphere acts as a fluid. The sun's radiation strikes the ground, thus warming the rocks. As the rock's temperature rises due to conduction, heat energy is released into the atmosphere, forming a bubble of air which is warmer than the surrounding air.

An aqueous solution of nitrous acid hno2 has a ph of 1. 96. The ionization constant of this acid is 5. 0 × 10−4. How much nitrous acid was used to prepare one liter of this solution?.
The number of moles of nitrous acid used to prepare the solution is 0.0021 moles.
pH of the HNO2 solution = 1. 96
Concentration of the HNO2 solution = Antilog(-1.96) = 0.011 M
We have to set up the ICE table as follows;
HNO2(aq) ⇄ H^+(aq) + NO2^-(aq)
I 0.011 0 0
C -x +x +x
E 0.011 - x x x
The dissociation constant of the acid is 5.0 × 10−4
Hence;
5.0 × 10−4 = x^2/ 0.011 - x
5.0 × 10−4(0.011 - x ) = x^2
5.5 × 10^-6 - 5.0 × 10^-4x = x^2
x^2 + 5.0 × 10^-4x - 5.5 × 10^-6 = 0
x= 0.0021 M
The concentration of the acid (H^+) in the solution is 0.0021 M. The number of moles of the acid is obtained from;
0.0021 M × 1 L = 0.0021 moles

lifes?
Answer: The information about sequential order of the event occurred in the past can be obtained by using only relative dating method.
Explanation:
Relative dating method doesn’t give information about when it happened. It provides sequential order of the events. It is the art of deciding the overall happening of past occasions (i.e., the age of an item in contrast with another), without fundamentally deciding their outright age (for example evaluated age).
In topography, shake or shallow stores, fossils and lithologies can be utilized to correspond one stratigraphic segment with another.

which best represents the number of moles in exactly 130 grams of potassium metal?
Answer:
if by EXACTLY means 130.0000, then the answer is 3.3250
by EXACTLY means 1.299 <Kmass<1.301 then the answer is 3.33
EXPLANATION
which best represents the number of moles in exactly 130 grams of potassium metal?
the elemental mass of K is 39.098
so exactly 130 divided by 39.098 = 3.3250
if by EXACTLY means 130.0000, then the solution is 3.3250 by EXACTLY means 1.299 <Kmass<1.301 is 3.33
What is Potassium Metal?
Potassium metal responds rapidly with atmospheric oxygen to create flaky white potassium peroxide in exclusively moments of exposure.
It stood preferably isolated from potash, the ashes of plants, from which its appellation derives.
In the systematic table, potassium is one of the alkali metals, all of which have a single valence electron in the outermost electron shell,
That is easily drawn to produce an ion with a positive charge a cation, that connects with anions to form salts. Potassium in disposition materializes only in ionic salts.
When the elementary mass of K is 39.098
Therefore, exactly 130 divided by 39.098 is = 3.3250

Distinguish between the first, second, and third ionization energies of an atom. b. How do the values of successive ionization energies compare
Answer:
The third ionization energy is the energy it takes to remove an electron from a 2+ ion. (That means that the atom has already lost two electrons, you are now removing the third.) And 2nd ionization energy is higher than 1st ionization energy, 3rd is higher than 2nd, and so forth.

Convection currents are one force driving plate tectonics. What other force plays a major role?
Heat transfer
Gravity
Radioactive decay
Fossil formation
Answer:
Gravity
Explanation:
Gravity was founded by famous physician Sir Izak Newton.The gravity is a phenomenon by which every object in the universe attracts eachotherNewton discovered gravity by the falling apple from tree.The following factors contribute to plate tectonics: The Mantle's Convection. Mountain push gravitational force at the spreading ridges, Block pull gravitational force in subduction zones. Hence, option B is correct.
What is gravitational force ?The gravitational force, which is what pushes mass-containing objects toward one another. We frequently consider the pull of gravity from the Earth. Your body is kept on the ground by this force. However, all mass-bearing objects are pulled toward one another by gravity.
Population growth and changes in people's wants and activities are the main causes behind this. Changes in the overall levels of output and consumption are caused by these main movers.
The driving forces put strain on the environment through these modifications to production and consumption. In the direction of motion, gravity produces an active driving force.
Thus, option B is correct.

The heat capacity of the calorimeter is 133.76 J°/C.
A calorimeter is an apparatus employed when estimating the amount of heat required in a chemical reaction.
For the given calorimetric function:

The new concentration of the solution that has 400.0 mL of a 0.425 M solution of NaCl diluted to 900.0 mL is 0.189M
HOW TO CALCULATE CONCENTRATION:
The concentration of a diluted solution can be calculated using the following formula:C1V1 = C2V2
Where;
C1 = initial concentrationC2 = final concentrationV1 = initial volumeV2 = final volumeAccording to this question, a solution of NaCl has 400.0 mL of a 0.425 M solution and diluted to 900.0 mL. The new concentration is as follows:400 × 0.425 = 900 × C2
170 = 900C2
C2 = 170 ÷ 900
C2 = 0.189M
