Answer:

The sharklet film creates a phenomenon reffed to as mechanotransduction.

Explanation:

It was discovered that sharks do not experience fouling , their skin is made in a distinct manner with diamond patterns that will discourage micro organism from settling on it.

Through the process of mechanotransduction, mechanical stress is created to the bacteria whereby they cannot attach themselves to the surface because it makes them to produce more energy to settle on the surface thus they may keep off from the surface. In this manner, bacteria is inhibited from attacking these areas protected by the sharklet film.

A 32.2 g iron rod, initially at 21.9 C, is submerged into an unknown mass of water at 63.5 C. in an insulated container. The fin

lorasvet [3.4K]

Answer : The mass of the water in two significant figures is, $3.0\times 10^1g$

Explanation :

In this case the heat given by the hot body is equal to the heat taken by the cold body.

$q_1=-q_2$

$m_1\times c_1\times (T_f-T_1)=-m_2\times c_2\times (T_f-T_2)$

where,

$c_1$ = specific heat of iron metal = $0.45J/g^oC$

$c_2$ = specific heat of water = $4.18J/g^oC$

$m_1$ = mass of iron metal = 32.3 g

$m_2$ = mass of water = ?

$T_f$ = final temperature of mixture = $59.2^oC$

$T_1$ = initial temperature of iron metal = $21.9^oC$

$T_2$ = initial temperature of water = $63.5^oC$

Now put all the given values in the above formula, we get

$32.3g\times 0.45J/g^oC\times (59.2-21.9)^oC=-m_2\times 4.18J/g^oC\times (59.2-63.5)^oC$

$m_2=30.16g\approx 3.0\times 10^1g$

Therefore, the mass of the water in two significant figures is, $3.0\times 10^1g$

Pairs

BabaBlast [244]

Atoms are made up of protons, neutrons, and electrons.

Energy can be neither created nor destroyed.

Water freezes at 0°C

If a piece of platinum is placed in acid, it will not react.

<h3>What are the correct pairing of the given terms?</h3>

The correct pairing of the given terms are obtained from the given options as follows:

Atoms of elements contains three sub-atomic particles which are protons, neutrons, and electrons.

Energy is the ability to do work.

According to the law of conservation of energy, Energy can be neither created nor destroyed.

Water is a liquid which freezes at 0°C.

Therefore, Water freezes at 0°C.

Platinum is a metal which is less reactive than hydrogen, Hence, it cannot displace hydrogen from acids.

Hence, if a piece of platinum is placed in acid, it will not react.

In conclusion, the correct pairing gives the correct description of the properties of the given terms.
