What is the difference between a molecular formula and a molecular model

Physics
1 answer:
Anon25 [30]3 years ago
7 0
The difference is one is a written formula that describes a molecule, the other is a visual representation of the molecule. for example the hydrocarbon butane has a molecular formula of C4H10, whereas the molecular model would depict 4 Carbon atoms (either represented by colour coded dots or the letter C) with single bonds (one straight line) connecting them to the 10 Hydrogen atoms (either differenly coloured dots or a H)

Freezing involves the ______________ of latent heat and a change is state from the ______________ phase to the solid phase.
DaniilM [7]
<span>Freezing involves the decrease in value of latent heat by 80 Cal/gm and a change of state from the Liquid phase to the solid phase.

So, in short, Fill in the blank as follows:
1st blank = Release/decrease
2nd blank = Liquid

Hope this helps!

1.2 m long spring with a spring force of 200.0 N/m, 12.0 kg mass is attached to it, find the length
Crank

From Hooke's law, the length of the spring after extension and after the mass is attached is 1.788 meters. Option B is the answer.

<h3>HOOKE'S LAW</h3>

Hooke's law state that in an elastic material, the force applied is directly proportional to the extension provided that the elastic limit is not exceeded.

Given that a 12.0 kg mass is attached to 1.2 m long spring with a spring constant of 200.0 N/m.

The given parameters are:

  • mass m = 12kg
  • Initial length L_{1} = 1.2 m
  • Spring constant K = 200 N/m
  • Extension e = ?

According to Hooke's law

F = Ke

But F = mg

mg = Ke

Substitute all the parameters into the formula to get extension e

12 x 9.8 = 200e

e = 117.6 / 200

e = 0.588 m

The length of the spring after extension and after the mass is attached will be

L_{2} = L_{1} + e

L_{2} = 1.2 + 0.588

L_{2} = 1.788 m

Therefore, the correct answer is option B because the length of the spring after extension and after the mass is attached is 1.788 meters.
