Why heat capacity for polymer higher than metal?

Physics
1 answer:

Because polymers are covalently bonded material, and metals are metalicly bonded material. 

Covalent bonds do not let atoms exchange electrons like metalic bonds do.

Examples of Selectively Permeable Membranes. Selectively permeable membranes can be found around a variety of cells and places. The most common example is the phospholipid bilayer cell membrane that surrounds every cell in our bodies. Another example of a selectively permeable membrane is the inner membranes of an egg.Nov 5, 2014

Why does an increase in temperature result in an increase in reaction rate?
lora16 [44]

Answer:

An increase in temperature typically increases the rate of reaction. An increase in temperature will raise the average kinetic energy of the reactant molecules. Therefore, a greater proportion of molecules will have the minimum energy necessary for an effective collision.

How does the law of conservation of energy apply to machines?
oksano4ka [1.4K]
<span>Energy transferred to a machine equals energy transferred from it. It is because according to conservation of energy we can't create or destroy energy so, energy remains constant however, their form can be change by machine's

In short, Your Answer would be Option C

Hope this helps!</span>

A compact car has a mass of 1380 kg . Assume that the car has one spring on each wheel, that the springs are identical, and that
astraxan [27]

Answer:

A) k=34867.3384\ N.m^{-1}

B) \omega'\approx84\ Hz

Explanation:

Given:

mass of car, m=1380\ kg

A)

frequency of spring oscillation, f=1.6\ Hz

We knkow the formula for spring oscillation frequency:

\omega=2\pi.f

\Rightarrow \sqrt{\frac{k_{eq}}{m} } =2\pi.f

\sqrt{\frac{k_{eq}}{1380} } =2\times \pi\times 1.6

k_{eq}=139469.3537\ N.m^{-1}

Now as we know that the springs are in parallel and their stiffness constant gets added up in parallel.

<u>So, the stiffness of each spring is (as they are identical):</u>

k=\frac{k_{eq}}{4}

k=\frac{139469.3537}{4}

k=34867.3384\ N.m^{-1}

B)

given that 4 passengers of mass 70 kg each are in the car, then the oscillation frequency:

\omega'=\sqrt{\frac{k_{eq}}{(m+70\times 4)} }

\omega'=\sqrt{\frac{139469.3537}{(1380+280)} }

\omega'\approx84\ Hz
