Ratling [72]2 years ago

Well usually people would get granola bars. But I wouldn't suggest that, it doesn't have that much protein. When my father was young he use to eat tuna, tuna has a lot of protein and that's a good source to get it from. Plus you can get tuna cheap instead of buying the over priced protein meals.

Which of the following is a false statement about dispersion forces? View Available Hint(s) Which of the following is a false st
icang [17]

Explanation :

Dispersion forces are also known as London dispersion forces. It is the weakest force. Also, it is the part of the Van der Waals forces.

(1) This force is exhibited by all atoms and molecules.

(2) These forces are the result of the fluctuations in the electron distribution within molecules or atoms. Due to these fluctuations, the electric field is created. The magnitude of this force is explained in terms of Hamaker constant 'A'.

(3) Dispersion forces result from the formation of instantaneous dipoles in a molecule or atom. When electrons are more concentrated in a place, instantaneous dipoles formed.

(4) Dispersion force magnitude depends on the amount of surface area available for interactions. If the area increases, the size of the atom also increase. As a result, stronger dispersion forces.

So, the false statement is "Dispersion forces always have a greater magnitude in molecules with a greater molar mass".

An automatic dryer spins wet clothes at an angular speed of 5.2 rad/s. Starting from rest, the dryer reaches its operating speed
Dvinal [7]
<h2>Time taken by dryer to come up to speed is 1.625 seconds.</h2>

Explanation:

We have equation of motion v = u + at

     Initial velocity, u =  0 rad/s

     Final velocity, v = 5.2 rad/s    

     Time, t = ?

     Acceleration, a = 3.2 rad/s²

     Substituting

                      v = u + at  

                      5.2 = 0 + 3.2 x t

                      t = 1.625 s

Time taken by dryer to come up to speed is 1.625 seconds.

Which of the following has the most momentum?
777dan777 [17]

Answer:

0.50 kg moving at 10 m/s

Explanation:

          mv = p

 0.50(10) = 5.0 kg•m/s

5.0(0.50) = 2.5 kg•m/s

         1(2) = 2 kg•m/s

 0.40(10) = 4.0 kg•m/s

A hollow metal sphere is electrically neutral (no excess charge). A small amount of negative charge is suddenly placed at one po
Marizza181 [45]

Answer:

The excess charge has distributed itself evenly over the outside surface of the sphere.

Explanation:

Since the hollow sphere is a conductor, it has free electrons that can move about within the sphere. In this light, an excess charge, the like charges repels each other, therefore ensuring that charges are spread as far apart as possible. There is therefore an evenly distributed charge on the outside surface of the sphere.
