Answer:
ocean waves are converted to electricity with wave energy converter, or WEC, devices. ... The surface portion moves faster than the submerged part, and the WEC converts that relative motion into electricity
The volume of a box with length 25 cm, height 25 cm and width 1.0 m is 0.0625m³.
Volume of the box which is a cuboid can be calculated by multiplying the length, breadth and height of the given box.
Volume of the box is given by the product of the length of the box, Height of the box and Breadth or width of the box.
Since, the box is a cuboid, hence the formula is given by the products of length, breadth and height.
Given,
length of the box= 25cm = 0.25m
Height of the box =25cm = 0.25m
width of the box= 1m
Volume = length × width × height of box
Volume = 0.25 × 0.25 × 1
Volume = 0.0625m³
The volume of the box is 0.0625m³.

Traits are determined by alleles.
1. Structure of an atom:-
The basic structure of an atom includes a tiny, relatively massive nucleus, containing at least one proton and usually one or more neutrons.Outside of the nucleus are energy levels (also called shells), which contain one or more electrons.
Properties of an atom:-
The neutrons have the greatest mass and have no charge. The protons have slightly less mass than the neutrons and are positively charged. The electrons have almost no mass and are negatively charged. The chemical properties of the atom are determined by the number of protons, in fact, by number and arrangement of electrons.
2. Elements and their chemical symbols :-
1) Sodium - Na
2) Carbon - C
3) Magnesium - Mg
4) Aluminium - Al
5) Silicon - Si
6) Chlorine - Cl
7) Potassium - K
8) Calcium - Ca
9) Copper - Cu
10) Iron - Fe
3. ionic bond
Covalent bond
Metallic bond
4. pH scale used to specify the acidity or basicity of an aqueous solution. Acidic solutions are measured to have lower pH values than basic or alkaline solutions
5. There are four natural states of matter: Solids, liquids, gases and plasma.
6. Law of conservation of mass :
The 'law of conservation of mass' says that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations. The mass of the products in a chemical reaction must equal the mass of the reactants.
Law of conservation of energy :-
According to the law of conservation of energy, energy can only be transformed from one form to another. It can neither be created nor destroyed. The total energy before and after the transformation always remains constant.
Hydrogen - 7.44%
Carbon - (100-7.44)% = 92.56%
Lets take 100 g of benzene, then we have
Hydrogen - 7.44 g
Carbon - 92.56 g
n - number of moles
n(H) = 7.44g *1 mol/1.0g = 7.44 mol
n(C) = 92.56 g* 1mol/12.0 g ≈ 7.713 mol
n(C) : n(H) = 7.713 mol : 7.44 mol = 1:1
Empirical formula is CH.
M(CH) = (12.0+ 1.00) g/mol = 13.0 g/mol
M (benzene) = 78.1 g/mol
M (benzene)/M(CH)= 78.1 g/mol/13.0 g/mol = 6
So, molecular formula of benzene is C6H6.
