Line.30. The line perpendicular to point where a ray of light reflects is called the
a. angle of reflection
b. angle of incidence
c. normal
d. law of reflection

Answers

Answer 1
Answer:

Answer:

c) Normal

Explanation:

Reflection is a phenomenon typical of light wave; it occurs when a ray of light hits the interface between two mediums, and bounces off back into the original medium, at a certain angle.

The direction of the reflected ray is determined by the law of reflection, which states that:

1) The incident ray and the reflected ray, together with the normal to the interface (the perpendicular to the interface), all lie within the same plane

2) The angle of incidence is equal to the angle of reflection:

\theta_i=\theta_r

where

\theta_i is measured as the angle between the incident ray and the normal to the interface

\theta_r is measured as the angle between the reflected ray and the normal to the interface

Which correctly describes molecule "a" in this diagram

Answers

Answer is: adenosine triphosphate.

ATP is made of three components: the triphosphate (P), the sugar ribose and a nitrogenous base (adenine).

ATP is short for adenosine triphosphate

Adenosine triphosphate converts to either the adenosine diphosphate (ADP) or adenosine monophosphate (AMP), in this process energy is released.  

The correct answer is A- Adenosine Triphosphate

write the equation for the combined gas law using temperature in degree Celsius. explain why the Kelvin scale is convenient​

Answers

Answer:

(PV)/(T)=k

Explanation:

Combine Gas law is a combination of  three gas laws which are  Boyle's Law, Charles' Law, and Gay-Lussac's Law.

Combine gas law states that the ratio of the product of pressure and volume and the absolute temperature of a gas is equal to a constant.

Hence the equation becomes:

(PV)/(T)=k

where P = pressure,

V = volume,

T = absolute temperature,

k = constant.

Now we know that Kelvin = °Celsius + 273

For all gas law problems it is necessary to work in the Kelvin scale because temperature is in the denominator in the combined gas laws (P/T, V/T and PV/T) and can be derived in the ideal gas law to the denominator (PV/RT) . If we measured temperature in Celsius we could have a value of zero degrees Celsius and this would solve as no solution, as you cannot have zero in the denominator.

However, if we reached zero in the Kelvin scale this would be absolute zero and all matter would stop and therefore there would be no gas laws to worry about.

What is pH level, what are its characteristics, and how does it contribute to pollution?

Answers

Answer:

pH Scale:

The pH scale refers to the negative logarithm of molar concentration of hydrogen ions: pH = -log [H+].

Characteristics:

The pH scale ranges from 0 to 14. A solution of a compound of pH 7 or pOH 7 is a neutral solution. Solutions of pH less than 7  are acidic and more than 7 are basic.

Low pH of water is acidic in nature as it enters into the ground and collects in streams, it can have bad impacts on the ecosystem.

It knows that when water evaporates, it carries heat energy away with it. 
So your body puts some water out on your skin, and hopes that it will
evaporate.  We call that "perspiring" or "sweating".
