An Asian elephant has a weight of 52,900 newtons. This enormous weight is balanced on four feet. In a circus act, these elephant

Aleonysh [2.5K]

Answer:

Option B, $18.11 \frac{N}{cm^{2}}$

Explanation:

Given-

The average surface area of one foot pad of an elephant is $2920$ $cm^{2}\\$

Weight of an Asian elephant is $52900$ newton

As we know, pressure is equal to total weight divided by total area of the surface on which it is concentrated.

Thus, pressure on one foot pad of elephant is $\frac{52900}{2920} \frac{N}{cm^{2}} \\$

$= 18.11\frac{N}{cm^{2}}$

Hence, option B is correct answer

Enter a nuclear equation for the fusion of two h-2 atoms to form he-3 and one neutron. express your answer as a nuclear equation

aliya0001 [1]

The nuclear equation that represents the fusion of two H-2 atoms to form He-3 and one neutron is

$\frac{2}{1} h + \frac{2}{1} h > > > > \frac{3}{2} he + \frac{1}{0} n$

In a nuclear reaction the nuclides are represented with the chemical symbol preceded by a superscript that represents the mass number (number of protons plus neutrons) and a subscript that represents the atomic number (number of protons).

<h3>What is a Nuclear reaction ?</h3>

A nuclear reaction is a process in nuclear physics and nuclear chemistry where two nuclei or a nucleus and an outside subatomic particle meet to create one or more new nuclides. Consequently, at least one nuclide must change throughout a nuclear reaction.

Interfacial adhesion and surface bioactivity of anodized titanium modified with SiON and SiONP surface coatings, The statement is correct.

<h3>what is adhesion ?</h3>

Adhesion is a type of attraction between two dissimilar phases, the theory of adhesion can be up two types mechanical interlocking and physical and chemical bonding and it is a combination of three methods.

Mechanical interlocking means when two dissimilar phases interact with one another by mechanical forces, requires a rough surface where the other material can enter.

Physical bonding includes van der Waals forces and the strength is rather weak and unable to contribute that much bonding strength.

Chemical bonding consist of covalent, ionic and metallic bonding which are more stronger than physical bonds and are responsible for cohesive forces.

chemical bonding between two dissimilar materials is more complicated due to the presence of few available bonding sites.
