True false according to current atomic theory electrons are in fixed locations

Physics
1 answer:
Amanda [17]3 years ago
4 0

That's <em>false.</em>  According to current atomic theory and quantum mechanics, an electron is always PROBABLY SOMEWHERE in a fuzzy foggy area around the nucleus of the atom, and that's all we can <u>ever</u> say about it.  There's no way to even TELL where the electron is, even if we <u>had</u> the technology to see things that small.

How does the type of medium affect a sound wave?
Llana [10]

The type of medium affects a sound wave as sound travels with the help of the vibration in particles. As different mediums have different amount and size of particles, for example, the speed of sound is faster through solid than liquid as solids have closely packed particles whereas liquids are loosely packed. Therefore the vibration is quicker in solids than liquids.

Hope it helps you! :)

Opposite electric charges will repel, and like charges will attract.
DochEvi [55]
As it stands now, that statement is false.

There are two ways to make the statement true:

#1).  Exchange the places of the words "Opposite" and "like".

#2).  Exchange the places of the words "repel" and "attract".

Either ONE of these changes will make the statement true.
Doing BOTH of these changes will leave it false.

Emily holds a banana of mass m over the edge of a bridge of height h. She drops the banana and it falls to the river below. Use
Mariana [72]

Answer:

The mass of the banana is m and it is at height h.

Applying the Law of Conservation of Energy

              Total Energy before fall = Total Energy after fall

                                E_{i}  = E_{f}

Here, total energy is the sum of kinetic energy and potential energy

K.E_{i} + P.E_{i} = K.E_{f} + P.E_{f}       (a)

When banana is at height h, it has

                 K.E_{i} = 0    and    P.E_{i} = mgh          

and when it reaches the river, it has

       K.E_{f}  = 1/2mv^{2}    and   P.E_{f}  = 0

Putting the values in equation (a)

                              0 + mgh = 1/2mv^{2} + 0

                                      mgh = 1/2mv^{2}

<em>cutting 'm' from both sides</em>

<em>                                           </em>gh = 1/2v^{2}

                                          v = \sqrt{2gh}

Hence, the velocity of banana before hitting the water is

                                          v = \sqrt{2gh}
