Answer: The question has some details missing. Here is the complete question ; An molecule adsorbed at one site on a surface. An oxygen molecule is adsorbed onto a small patch of the surface of a catalyst. It's known that the molecule is adsorbed on 1 of 576 possible sites for adsorption (see sketch at right). Calculate the entropy of this system. Round your answer to 3 significant digits.

Explanation:

The stefan boltzmaan constant for entropy is given by ;

  • S = kInw
  • we are given that 576 total possible sites in which O2 can get absorbed
  • w = 576, k = 1.38 x 10-23J/k

plugging the values into the equation ;

S = 1.38 x 10-23J/k X In(576)

Entropy of the system = 8.79 X 10-23J/k

A water rocket has a mass of 0.8kg and is launched in a school playground with an inital upwards force of 12newtons. what is the
Darina [25.2K]

Weight = (mass) x (gravity).
It always acts downward.

On Earth, the acceleration of gravity is 9.807 m/s².
On the Moon, the acceleration of gravity is 1.623 m/s².

On Earth, the rocket's weight is  (0.8kg) x (9.8 m/s²) = 7.84 newtons

On the Moon, the rocket's weight is  (0.8kg) x (1.62 m/s²) = 1.3 newtons

The force of the rocket engine acts upward.
Its magnitude is 12 newtons. (From the burning chemicals.
Doesn't depend on local gravity. Same force everywhere.)

Now we have all the data we need to mash together and calculate the
answers to the question.  You might choose a different method, but the
machine that I have selected to do the mashing with is Newton's 2nd law
of motion:

                           Net Force = (mass) x (acceleration).
 
Since the question is asking for acceleration, let's first solve Newton's law
for it.  Divide each side by (mass) and we have

                           Acceleration = (net force) / (mass) .

On Earth, the forces on the rocket are

        (weight of 7.84 N down) + (blast of 12 N up) =  4.16 newtons UP (net)

         Acceleration = (4.16 newtons UP) / (0.8 kg) = 5.2 m/s² UP .

On the moon, the forces on the rocket are

         (weight of 1.3 N down) + (blast of 12 N up) = 10.7 newtons UP (net)

         Acceleration = (10.7 newtons UP) / (0.8 kg) = 13.375 m/s² UP

What factors affect the strength of the electric force between two objects
Nady [450]
There are three factors:

The charge of the two objects. The electric force is proporcional to the product of the charges of both objects.

The distance that separetes them. The electric force is proportional to the inverse of the squared distance that separates the objects.

The media. The electric force constant of proportionality depends on the media: air, water, oil, glass.

What is the difference between the purines and the pyrimidines?
Natali [406]
They both are types or categories of nitrogen containing bases present in nuclei acids of DNA and RNA.

Purines are 2 Ring or Carbon Ring, Nitrogen containing bases. That consist of these 2 rings next placed next to each other. These examples include - Adenine and Guanine.

Pyrimidines are 1 or single Ring Nitrogen containing structures. There are 3 nitrogenous bases that are categorized as pyrimidines. Cytosine, Thymine, and Uracil.
