# What is Degrees: Definition and 676 Discussions

An academic degree is a qualification awarded to students upon successful completion of a course of study in higher education, usually at a college or university. These institutions commonly offer degrees at various levels, usually including bachelor's, master's and doctorates, often alongside other academic certificates and professional degrees. The most common undergraduate degree is the bachelor's degree, although in some countries there are lower level higher education qualifications that are also titled degrees (e.g. associate degrees and foundation degrees).

1. ### I How does BTU convert to heat in degrees in a greenhouse?

Information online claims sun is 200 btu per sq ft in winter only when sun is perpendicular to plastic or glass of a green house. When sun hits glass or plastic at an angle there are losses. The steeper the angle the more losses will be. Is it possible to calculate how warm a green house will...
2. ### Evaluating the angle theta using inverse sin

I just need to know how to find Θ in sin2Θ=0.51 I know I can use Θ = arcsin(0.51) but what about sin2Θ = 0.51
3. ### Degrees of freedom (question based on an interview I attended)

I was asked by an interviewer the number of degrees of freedom (in both translation and rotational senses) this part has with respect to each axis. Indeed I can share what I think of here, but I want to start it fresh and correct. If you were the interviewee, what would have been your answer and...
4. ### Why does a wrist have 3 degrees of freedom?

The other two movements make use of the wrist and can't be done without it so I see why they are considered to be degrees of freedom of the wrist.
5. ### A Two degrees of freedom in GR after boundary conditions specified?

I read there are 2 degrees of freedom in GR after boundary conditions specified. Does that mean 2 equations are enough for EFE equivalent? Those two seem like the amplitude and a phase.
6. ### Degrees of freedom and holonomic constraints

Hi, I am not quite sure if I have solved task 2a and 2b correctly. For task 2a I would say, because of the constraints, that the system has only 1 degree of freedom. Since the vectors must always have an angle of Pi/4 to each other, this would mean that if one vector moves up, the other must...
7. ### I Degrees of freedom and constraints

In case of P holonomic constraints and N particles, I have 3N-P degrees of freedom and I have to look for 3N-P generalized coordinates if I want them to vary independently, but what about non-holonomic constraints? I know if I have N particles and P non-holonomic constraints, I still need 3N...
8. ### Job Skills Why is CS in more favorable over other IT degrees?

So recently what I've been seeing especially on reddit was that people have been praising CS over other IT degrees. Why is that a trend? Is it because other IT degrees are seen as "obsolete"?
9. ### I Dimensions vs. degrees of freedom

Are dimensions the same thing as degrees of freedom? Would you say that a circle is a one dimensional object embedded in a two dimensional space?
10. ### How can the degrees of freedom of a mechanism be obtained?

Summary: ##M=3\left(n-1\right)-2j_1-j_2## Hi, I'm trying to get the degrees of freedom of a can crusher. So substituting I get ## \begin{array}{l}M=3\left(n-1\right)-2j_1-j_2\\ n=5\\ j_1=5\\ M=3\left(5-1\right)-2\cdot 5-0\\ M=2\end{array} ## And I would think it would be 1
11. ### Programs What Is a Doctor of Engineering Degree and How Does It Work?

I've recently learned that "Doctor of Engineering" degrees were a thing. It's seems to be a collaboration between the school and the company they work for. Does anyone here have one? Are these programs meant to be completed while continuing to work in industry full time? I couldn't find this...

I have a spherical concave mirror with focal length of 65cm, radius of curvature of 130cm. I hold the mirror close to the eye at approximate 45 degrees and I reflect an object below it as shown in the image. The distance between the object and the mirror is 90cm, that is more than the focal...
19. ### Degrees of freedom of "simple bicycle"

Hi I thought that a bike could be simply modeled as two wheels attached by a rigid bar. If the wheels move without sliding, then there is one degree of freedom: one of the wheels moves and so does the other one since they are rigidly attached by the bar. Then, if the wheels can turn to the right...
20. ### Why do we not need to convert from degrees Celsius to Kelvin?

I understand that the Kelvin scale begins at absolute zero and that the Kelvin scale may even be referred to as the absolute scale. As the units begin from a definite zero and increase with equal amounts of energy being added to the particles of the substance being measured (at equal intervals...
21. ### Degrees of freedom with a particle and a rod

The rod itself should have 3 translational+2 rotational DOF. The particle on top of the rod has one additional DOF. So total should be 6. But answer given is 4. What I'm thinking wrong?
22. ### I What do physicists mean by "local degrees of freedom"?

I have an empirical frequency distribution as for example below: ##f_{2} = \, \, \, 21## ##f_{3} = 111## ##f_{4} = \, \, \, 24## The theoretical distribution is determined by two parameters. So for a chi-square goodness-of-fit test there are actually no degrees of freedom left. Yet the...

30. ### Degrees of freedom of a water molecule

Well, first of all is really good to say that we don't can appeal to quantum mechanics... So, i can see: Three degree of freedoms in translation on a space xyz +3 degree Three normal modes of vibration, but each normal mode has with it a potential and vibrational kinetic energy, so +6 degree...
31. ### A Degrees of freedom of thin rods

(Note: I had this question posted at the intermediate level of difficulty for 11 days, but got only one, cryptic (to me) response that was rather quickly removed. So, I figured perhaps it's actually an advanced question, requiring more than a cursory understanding.) Assuming they've had an...

34. ### Thermodynamic state having 2 degrees of freedom (i.e., for properties)

I'm trying to delve into the reason why this is so. It seems that there are 5 fundamental properties: P - Pressure V - Volume (specific) T - Temperature S - Entropy (specific) U - Internal Energy (Yes, there are other types of energy, but they are fully determinable from these 5 - e.g...
35. ### Understanding Energy of Particles with 'x' Degrees of Freedom

I've learned that for a particle having 3 degrees of freedom, its average energy is 3/2 kT. So for a particle having 'x' degrees of freedom, its energy should be xkT/2. So what is the use of given E = ax6 here? Please help!
36. ### I What are the degrees of freedom of a quark?

In computer science we simplify lots of things down to arrays. Tensor equations just show the symmetries between these multidimensional arrays. And any model of a quark in our ordered world must have N degrees of freedom. The term called Degrees of Freedom is simple enough. For example a XYZ...

Planck states that all perfect crystalline system have the same entropy in limit T approaches zero,so we can put the entropy equal zero.Can we demonstrate that or is it only a presumption?
38. ### B Why do we need values greater than 90 degrees?

I can't understand how can we assign values greater than 90 to trigonometric functions as right angle triangle can't exist if one angle is more than 90 degree. For example if I say sin 30 according to me it means that ratio of perpendicular and hypotenuse is 1/2 at 30 degree but how can we say...
