What is Salt water solution?
Salt and water are combined to form a saline solution. Normal saline solution has a sodium chloride (salt) content of 0.9 percent, which is comparable to the sodium content of blood and tears.
Normal saline is the name given to saline solution most often, but it can also be referred to as physiological or isotonic saline.
Saline is used extensively in medicine. It is applied to cure dehydration, cleanse sinuses, and clean wounds. It can be injected into a vein or administered topically.
Therefore, Five grams of salt dissolved in 100ml of water to form a salt-water solution. The solution is heated and the water boiled away. five grams of salt would you expect to have left in the container.

On Earth, 1 kg of mass weighs 9.807 Newtons, or 2.205 pounds (both rounded). The book with mass 1.5 kg weighs 14.7 Newtons, or 3.31 pounds.
Final answer:
To find the mass of a book that weighs 14.7 Newtons, we divide this weight by the acceleration due to gravity, 9.8 m/s², resulting in a mass of approximately 1.5 kilograms.
Explanation:
In order to find the mass of an object from its weight, we use the formula: mass = weight / gravity. Gravity on Earth is about 9.8 m/s².
To find the mass of a book that weighs 14.7 Newtons, we have to divide the weight by the acceleration due to gravity. This results in: mass = 14.7 N / 9.8 m/s² = 1.5kg.
So, the mass of the book is approximately 1.5 kilograms.

Answer:
Mechanical energy
Explanation:
Mechanical energy is the energy of an object because of potential and kinetic energies. It is the sum of both kinetic and potential energies.
Kinetic energy is given by the motion of an object while the potential energy is possessed due to its height above ground level. It is also called the total energy of an object. Mathematically, mechanical energy is given by :

The correct answer is option B
The mining of uranium is harmful for both air and water. Uranium is a radioactive compound that is extracted by mining.
Uranium ore emits the gas named radon. The health effects of exposure to radon have particular problems. Significant rate of lungs cancer was observed during the 1940s and 1950s.
Water is used in the heap leaching of the uranium mining. The water can get mixed into the normal supply of water and harm the health of people.
Mining of the radioactive element Uranium has the following negative effects on both air and water such as contamination.
What is Uranium?
This is a a silvery-white metallic chemical element in the periodic table, with atomic number 92 and is commonly used to run nuclear power plant.
it exists in the air and when contaminates water could lead to kidneyailments in affected individuals which is why option B was chosen as the most appropriate choice.
