Answer:
I'm not exactly 100% sure sorry
The electrons in an atom can only occupy certain allowed energy levels. ... Only certain energy levels are allowed, so only certain transitions are possible and hence specific wavelengths are emitted when an electron drops to a lower energy level
Explanation:
Answer:
B. Both of the crates are accelerating at the same rate.
Explanation:
This is a <em>conceptual</em> question. Ignore the values. This is a <em>trick</em> question.
My question to you: both of these crates are falling on Earth, right?
Now chew on this:
What's the value of acceleration due to gravity on Earth?
Hope this helps you! Have a great day!
Surface tension and surface energy are two very important concepts discussed in physics. The concepts of surface tension and surface energy are widely used in fields such as fluid mechanics, fluid dynamics, aerodynamics and various other fields. Surface tension is the net intermolecular force on the surface molecules of a liquid. Surface energy is the relevant energy of these bonds. In this article, we are going to discuss what surface tension and surface energy are, their applications, the definitions of surface tension and surface energy, their similarities, and finally the difference between surface tension and surface energy.
The change in surface area of Gaussian surface with radius (r) is 8πr.
<h3>
Electric field from Coulomb's law</h3>
The electric field experienced by a charge is calculated as follows;
where;
- E is the electric field
- Q is the charge
- r is the radius
The electric field reduces by a factor of
<h3>Surface area of a Gaussian surface;</h3>
The surface area of a sphere is given as;
<h3>Change in area with r</h3>
Thus, the change in surface area of Gaussian surface with radius (r) is 8πr.
