how do upper fixed point calibrate in a thermometer ? Explain it .
Answer:
To mark the upper fixed point, the thermometer is placed in a hypsometer containing water as shown in the figure. The bulb of the thermometer should be outside the water. When the mercury level becomes stationary at a temperature of steam, the level is marked, which represents the upper fixed point of the thermometer.

As the mass of an object increases, what happens to the gravitational force created by that object?
Answer:
the gravitational force is proportional to the mass of both interacting objects, bigger objects will attract each other with a greater gravitational force. So the mass of either object increases, the force of gravitational attraction between them also increases.
Answer:
Since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force.So the gravitational attraction between them also increases.

How many different elements are in this equation? NaCl + AgNO3 --> NaNO3 + AgCl
Answer:
5 elements
Explanation:
Na, Cl, Ag, N, O are all separate elements because the first letter of an element is always capital and the second one is lowercase
The different chemical elements present in this equation NaCl + AgNO₃ --> NaNO₃ + AgCl are Na, Cl, Ag, N, and O.
What are chemical elements?Chemical elements are pure substances that contain only atoms and have the same amount of protons in the nuclei.
There are a total of 118 elements are present in a periodic table.
The elements present in the given equation are:
Na- sodium, Cl-chlorine, Ag-silver, N-nitrogen, and O-oxygen.
Thus, the elements present in the equation are Na, Cl, Ag, N, and O.

1. Explain the two processes that keep atmospheric oxygen and carbon dioxide at stable levels?
2. What do you think are two causes of the increase in carbon dioxide in the atmosphere?
Cellular Respiration and Photosynthesis. Photosynthesis is the process of when plants use sunlight to make foods from carbon dioxide and water, to later on make oxygen. Cellular respiration is the process through which cells convert sugars into energy.
Which equation represents a fusion reaction?
Answer:
B
Explanation:
I took the test
The equation that represents a fusion reaction is ²₁H + ²₁H = ⁴₂He and the correct option D.
A fusion reaction is a type of nuclear reaction that involves the merging or combining of two or more atomic nuclei to form a heavier nucleus. This process releases a significant amount of energy.
In fusion reactions, the atomic nuclei overcome the electrostatic repulsion between positively charged protons and come close enough for the strong nuclear force to bind them together. This typically occurs at extremely high temperatures and pressures, such as those found in the core of stars or in experimental fusion reactors.
The most well-known fusion reaction is the fusion of hydrogen isotopes, deuterium and tritium, to form helium. This reaction is the primary process that powers the Sun and other stars, and it is also the focus of research efforts to achieve controlled nuclear fusion for practical energy production on Earth.
Thus, the ideal selection is option D.

EXPLAIN
Answer:
Mechanoreceptors
Explanation:
If Propriorceptors are for sensing light, thermoreceptors are for decenting temperatures, and pain receptors are for detecting injury, then mechanoreceptors would be used for sensing touch, and in this case you are touching the iphone screen, so mechanoreceptors is the correct answer.
