A wave with a height of 5 feet and a wavelength of 15 feet has a wave base of___.
dmitriy555 [2]

A wave with a height of 5 feet and a wavelength of 15 feet has a wave base of <u>7.5 feet</u>.

A. 7.5 feet

<u>Explanation:</u>

Wave base defines the depth of the water when it is in still condition.

Wave base is half of wavelength.

Wave base = wavelength/2

Given,

Wavelength = 15 feet

So, wave base = 15 feet/2 = 7.5 feet

When the wave height is divided by wavelength then it gives the steepness of the wave.

Therefore, the wave base is 7.5feet.

The-attraction of the positive side of one water
Anna71 [15]

Answer:

B = hydrogen bonding

Explanation:

The water molecule consist of two hydrogen atom one oxygen atom. There is large electronegativity difference between oxygen and hydrogen. Both atoms are bonded through covalent bonds.

Covalent bond:

It is formed by the sharing of electron pair between bonded atoms.  

The atom with larger electronegativity attract the electron pair more towards it self and becomes partial negative while the other atom becomes partial positive.

For example:

In water the electronegativity of oxygen is 3.44 and hydrogen is 2.2. That's why electron pair attracted more towards oxygen, thus oxygen becomes partial negative and hydrogen becomes partial negative.  The partial positive end of one water molecule attracted towards the partial negative end of other moleucle. The attraction between them is called hydrogen bonding. In this way large mole are connected with each other. Hydrogen bonding is actually a weak bonding.

How does the Classification system distinguish between organisms?
polet [3.4K]

Answer:

By organising them into five major kingdoms and further dividing each kingdom into phyla (or divisions), classes, orders, families, genus, and species.

Explanation:

There are five kingdoms:

  1. Monera: bacteria
  2. Protista: amoeba, paramecium, euglena
  3. Fungi: yeast, rhizopus
  4. Plantae: flowering and non-flowering plants
  5. Animalia: animals (vertebrates and invertebrates)

Organisms that share the most similar features are grouped into the same species. Species with similar features fall under the same genus. Several genus make up a family, several families make up an order, several orders make up a class, several classes make up a phylum (or division), and several phyla (or divisions) make up a kingdom.

Note: there are three domains (or superkingdoms): Archea, Bacteria, and Eukarya.
