Answer:
<h2>2.58 mL</h2>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula
From the question we have
mass = 31 g
density = 12 g/mL
We have the final answer as
<h3>2.58 mL</h3>
Hope this helps you
Answer:
4: Hydro electrical energy
5:Flase the law of conservation of energy is not violated by transformer.
Explanation:
4:Hydroelectric energy, also called hydroelectric power or hydroelectricity, is a form of energy that harnesses the power of water in motion—such as water flowing over a waterfall—to generate electricity. People have used this force for millennia.
5:Quantum Physics and Law of Conservation of Energy.
Niels Bohr, Hans Kramers, and John Slater proposed that these electrons violated the law of conservation of Energy momentarily. They stated that with each jump, energy is either created or destroyed by the electrons during the whole process.
The formula for an isotope of oxygen with nine neutrons, including the mass number and the atomic number is 17/8 O.
<h3>What is an isotope?</h3>
Isotope is any of two or more forms of an element where the atoms have the same number of protons, but a different number of neutrons within their nuclei.
This means that atoms of isotopes will have the same atomic number but a different mass number.
According to this question, an isotope of oxygen has 9 neutrons. If oxygen has an atomic number of 8, the formula of this particular isotope is as follows: 17/8 O.

Answer:
Potential energy is the energy stored within an object, due to the object's position, arrangement or state. Potential energy is one of the two main forms of energy, along with kinetic energy.
