An object has a weight of 5.10 Newtons (N) at sea level, where the acceleration due to gravity is 9.81 m/s2.What is the acceleration due to gravity on the object of it is placed in a space ship 1,000 km above sea level, where gravity exerts a force of 3.81 N on the object. F(newtons)=m(kg) x a(m/s2) Please show work.

Answer:
Well, you could get the mass as m=\frac{G_0}{g_0} ad then g_1=\frac{G_1}{m}, where G_0 is the sea level weight, g_0 the sea level accel., g_1 the accel. above while G_1 the weight above

An element's chemical properties are determined by the number ofelectrons .
How do electrons determine chemical properties?
The number of electrons determine chemical properties of an atom as they are present in equal number outside the nucleus as that of protons .Protons contribute to the mass of an atom and give an identity to an atom .
As protons are positively charged there is a need to balance this positive charge and it is balanced by an equal number of electrons .As the valence electrons are the electrons which take part in chemicalreactions the element's chemical properties are determined by the number of electrons.
The number of neutrons has a negligible effect on the chemical nature of elements as they are neutral and have no charge.Indirectly, it's the electronic configuration of an element which determines the chemical properties of any element.

Answer: Identical to its parent.
Explanation:
The cloning can be defined as the process by which genetically identical individuals of an organism is produced either artificially or naturally.
The cloning in case of biotechnology refers to the creating the clones of organisms or copies of cells or DNA of the parent cell that is being used in the process.
The parent cell is cloned and numerous copies is made just like that of the asexual reproduction in the nature.
Example: Dolly the sheep.
A cell created by cloning is genetically identical to its parent. The correct answer is option A.
DNA (deoxyribonucleic acid) is a molecule that carries genetic information and instructions for the development and function of all living organisms.
When a cell is cloned, it is essentially a copy of the original cell. This means that the genetic material in the cloned cell is identical to the genetic material in the original cell.
- The DNA in the cloned cell is exactly the same as the DNA in the parent cell, and there is no mixing or recombination of DNA from different sources.
In conclusion, the correct answer is A) identical to its parent. A cell created by cloning is genetically identical to its parent.

Answer:
The correct answer is A. Stomach
Explanation:
The prefix gastro- is derived from the Greek word gastrós or gaster wich means stomach, the organ responsible for digestion of food. The most common examples are:
- Gastrointestinal: related to stomach and intestines
- Gastritis: inflammation of the stomach
- Gastroenteritis: inflammation of both stomach and intestines
A combining form with the meaning "stomach," is often used to create compound words, such as gastrology. Here the root word gastro means Stomach. The correct option is A.
The stomach is a muscular bag-like organ that is located on the left side of the upper abdomen. The esophageal sphincter, a valve, is used by the oesophagus to transfer food to the stomach. Acid and digestive enzymes are produced in the stomach to aid in meal digestion.
Storing and digesting the food and liquid consumed during meals is the stomach's main job. In order to aid in the digestion of food and other external items like germs, it creates hydrochloric acid and enzymes.
Thus the correct option is A.
