Answer:
The answer of this question is =1.258*10-4
The answer would be: element helium
Answer:
According to II law of thermodynamics the heat always transfers from high temperature to low temperature body without aid of any external energy. So, according to this law the heat transfers from cup of coffee to the person body until both bodies reaches to the equilibrium state.
After attaining the equilibrium state, the heat transfer may be ceases between the bodies.
Whenever the person touches the hot coffee, he senses the heat that means the heat is transferring in to his body.
he number following the symbol represents a change in neutrons and mass numbers.
<u>Explanation:</u>
The chemical symbol is the abbreviation used to identify the element or atom of the element. The isotope symbols of specific element is recorded by placing a mass number as superscript in left to the element's symbol. The protons count (also referred as atomic number) as subscript precedes the symbol. For example, magnesium is the three isotopes mixture with 12 as atomic number and a mass numbers as 24, 25 and 26.
These isotopes can identify as . These isotope symbols are read as "element, mass number" and can be symbolized by this reading. For example, is read as "Magnesium 24" and so on. All magnesium atoms contain 12 protons in the nucleus. So, it indicates the neutron variation and mass numbers.
To get it to start moving, he have to exert a force equal to its maximum force of static friction.
F= fs,max = Ms m g= (0.21) * (180) * (9.8) = 370 N
Let me know if im wrong but if not brainliest user for helping or best answer
