In the solution to this question, they have first taken the component of downwards-acting gravity(g) along the incline which is the sin component then again they have taken the component of the gsin along the x-axis and y-axis. Now my question is how are we supposed to take the component of a component and why not just... | 0 |
Say we have a plate full of soup, why to cool it down we move the spoon around in the plate? Is it to facilitate the thermal interchange between the air and the soup? Also why is the edge of the plate always cooler than the center of the plate? It may be because of how close it is to the plate so it exchanges heat with... | 0 |
are modus ponens and tollens axioms if not how can they be derived or proved? if I am good at math then I am good at logic, I am good at math, therofe I am good at logic this seems evident but is there any proof for them? looking at the truth table for implication we see p->q is true when P is true and Q is true | 0 |

For college, we are supposed to hand in uncompiled .tex files for the teacher to make the .pdf themselves. However, college computers have very few packages installed ; but I have heard somewhere that one can include the package along with the .tex source. I cannot find a guide on how to do this, can someone explain ho... | 0 |
Good day, I am a lay person in this field So i am very sorry if my question Is dumb. I am wondering whether the Hypothesis H formulated by Schreiber and Sati stating that C-field is charge quantized in J-twisted Cohomotopy theory doesnt assume already existing spacetime manifold And a C-field which would together const... | 0 |
Premise: Verb 'want' is normally (?) stative We use adverbs when we have an action verb and adjectives when the verb is stative In sentence "I want it bad(ly)" we would use the adverb 'badly' and not adjective 'bad' --> "I want it badly" (correct) From that we can infer that the verb 'want' is then an action one. But i... | 0 |
By Definition Electric field vectors point in the same direction as the electric force that a (hypothetical) positive test charge would experience, if placed in the field. Electric Field Lines are generated by connecting all of electric field vectors together, forming continuous lines and curves. What does electric fie... | 0 |
I am currently doing some writing, and constantly try to create smooth transition and ease of readability and linkage between sentences. This sentence feels like it kind of halts the reader a bit.

Knowing the strength of concrete you can get the mass of an object put on a concrete block is able to withstand on given area. As for a falling object, kinetic energy itself doesn't translate to force, so the force decelerating the object while collision occurs is somehow defined by material properties of the block (fo... | 0 |
I am looking for a bell-shaped periodic function f(x) with parameters a and b, with following characteristics: ( not sure if such function already exists or one can formulate one ) : oscillating between zero and a constant non-negative number A.

Is there a way to avoid division through size n in ift (ifft) ? Performing the Inverse (Fast) Fourier Transform on the complexnumbers, you go with a for loop through every element dividing it through the sizeof (dimension) of the array, to complete the last step of the inverse fourier transform. Is there a (more effici... | 0 |
If you take empty space right next to a black hole once in awhile, you will get a positive particle being admitted in the opposite direction of the black hole. In the creation of the photon this demands that a negative energy is supplied in the opposite direction of the positive particle which would be into the black h... | 0 |

If we think about inertial mass and gravitational mass as independent concepts and develop physics then we would know after a while they are only propotional (by precision we have by now). but it seem physicist say they are equal. when in history they became equal? two guesses: Newton himself says gravitional force is ... | 0 |
The theory only deals with the local curvatures, not the global topology. Hence any manifold with an allowed metric is allowed. These can be infinitely many, especially for negative curvature space-times. From So I suppose for the same physical situation, there would be many manifolds from which it can be studied, then... | 0 |
When charge moves at a constant speed, it is said that it produces static magnetic and electric field. Why static ? If it moves, at every points, electric field and magnetic field change as they are dependent on a distance to the point. So even if charge moves at constant speed, we still should have electric and magnet... | 0 |

The identations would cause it to exactly follow the curve. ...but...why? Why does... | 0 |
Suppose we work in GR, then space time is four dimensions, but, if we have a mechanical system with a high number of degree of freedoms, say five then how would we fit it into a four dimensional space time. Now that'd obviously be impossible, it'd suggest that the sense we talk about dimensions of physical system is di... | 0 |
in our physics lessons we often learn how to calculate the time that sound of a plane that travels faster than sound takes to reach us using the Mach cone.
