Answers
Answer:
E i think.
Explanation:
The triple-point of water occurs at 273.16 K (0.01 °C) and a vapor pressure of 0.0060373 atm. At this point water can be solid, liquid and gas. So, option (D) is correct.
What is phase diagram?phase diagram: a graph that displays the limiting conditions for a substance's solid, liquid, and gaseous phases under changes in pressure, temperature, or another combination of variables, such as solubility and temperature.
The curves in the figure were derived from measurements taken at various pressures and temperatures, and they represent a typical phase diagram for a one-component system (i.e., one made up of a single pure chemical).
What is triple-point?The combination of temperature and pressure at which a substance can exist in all three of its states—gas, liquid, and solid—is known as the triple point.
The Kelvin(K), the International System of Units' (SI) fundamental unit of thermodynamic temperature, is defined using the triple point of water. The triple-point of water occurs at 273.16 K (0.01 °C) and a vapor pressure of 0.0060373 atm.

Geologists use tools other than the law of superposition to help them with relative dating. Which statements describe those tools? Check all that apply.
Answers
Answer: Cross-cutting features are always younger than the surrounding rock.
When material erodes before sediment is deposited on it, a geologic gap results.
Explanation:
The options include:
1. An unconformity is created when lava pours out on Earth’s surface.
2. Faults are the result of volcanic activity.
3. Intrusions and extrusions are sedimentary formations.
4. Cross-cutting features are always younger than the surrounding rock.
5. When material erodes before sediment is deposited on it, a geologic gap results.
The law of superposition simply states that when there is a layers of rocks, we would see that the younger layers will lie and be on top of the layers that are older.
Other tools that can help scientist with relative dating are:
• Cross-cutting features are always younger than the surrounding rock.
• When material erodes before sediment is deposited on it, a geologic gap results.

Answers
Answer:
[tex]\mu =0.169704 Ns/m^2[/tex]
Explanation:
From the question we are told that
Area of plate[tex]a=1m^2[/tex]
Angle of inclination [tex]\theta=60 \textdegree[/tex]
Velocity [tex]v=0.75m/s[/tex]
Thickness of oil [tex]t=2mm[/tex]
Weight of plate [tex]w=90N[/tex]
Generally the equation for shear force is mathematically given by
[tex]F=mgsin45 \textdegree[/tex]
[tex]F=90sin45 \textdegree[/tex]
[tex]F=63.639N[/tex]
[tex]F=\mu* \frac{v}{t}[/tex]
[tex]F=\mu* \frac{0.75}{2*10^-^3}[/tex]
[tex]\mu* \frac{0.75}{2*10^-^3}=63.639N[/tex]
[tex]\mu =\frac{63.639}{375}[/tex]
Therefore viscosity is given by

Answers
A person’s blood type depends on the type of protein marker, called an Antigen, found on the cell membranes of the red blood cell.
What is antigen?A molecule known as an antigen is one that triggers the formation of an antibody and the immune system's response.
Large protein molecules known as antigens are found on the surface of pathogens like bacteria, fungi, viruses, and other foreign substances. When these dangerous substances enter the body, the body's immune system reacts by producing antibodies.
The ABO system distinguishes 4 major blood types:
Blood group O - has no antigens, but both anti-A and anti-B antibodies in the plasma. Blood group AB - has both A and B antigens, but no antibodies.Blood group A - has A antigens on the red blood cells with anti-B antibodies in the plasma.

what is the approximate increase in thermal energy in joules when the temperature of 15 grams of water is raised from 20° to 35° C. the specific heat of water is 4.19 j/g degrees Celsius
Answers
Answer:
942.75J
Explanation:
Change in thermal energy is equal to the mass of the given substance times the specific heat capacity times the temperature change.
We've already been given the specific heat capacity, the mass as well as the initial and final temperatures.
So change in temperature will be 35° - 20° = 15°
Thermal energy change = 15 × 15 × 4.19
The final answer is 942.75J

When water waves meet, they can combine to form new waves. In constructive waves, a ________ amplitude wave is formed. In destructive waves, a wave with a __________ amplitude is formed. A) greater, smaller B) smaller, greater C) smaller, smaller D) greater, greater
Answers
Answer:
In constructive waves, a greater amplitude wave is formed. In destructive waves, a wave with a smaller amplitude is formed. (option A)
Explanation:
Interference is called the superposition or sum of two or more waves. Depending mainly on the wavelengths, amplitudes and the relative distance between them, there are two types of interference: constructive or destructive.
Constructive interference occurs when there are two waves of identical or similar frequency (both have motions equal to an even number of similar wavelengths) and overlap the peak of one with the peak of the other. These effects add together and make a wave of greater amplitude. All of this is possible because the waves were in the same phase in the beginning (in the same position).
Destructive interference occurs in the opposite case to constructive. When the crest of one wave overlaps the valley of the other, they cancel out since they are in different phases when they overlap (they were in different positions). That is, as in the case of constructive waves they were added, in the case of destructive waves they cancel out (subtract).
So, In constructive waves, a greater amplitude wave is formed. In destructive waves, a wave with a smaller amplitude is formed.
