Hm, ok I'm more confused. Can you change the fact that V1 > V0 remaining in the same inertial frame ?

Hi to everybody ! I was thinking about something which confuses me about wave emission. The question is simply the following: Does an electron emit light when it accelerate? or just during its deceleration? or maybe when acceleration and deceleration alternates in some order? I'm not really...

I'm just worried about the steelwork near my home. Even if somebody measure emissions every once in a while, two problems can arise: 1) In some particular time frame (for example night) the steelwork could also emits more than usual pollution; it means that emissions control which are eventually...

Thanks for your reply. Do you know however, how it should be performed?

I have a steelworks nearby my home. Is it possible to perform an air analysis in order to know how much the air is polluted? Which instrument do I need ? Are there cheap possibilities? Thanks a lot in advance for your help!

Good inputs to think about.. Thanks again !

Hello everybody, I'm a little bit confused about two types of amplitude modulation. We distinguish here: Case I : Amplitude Modulation with suppressed carrier (https://en.wikipedia.org/wiki/Double-sideband_suppressed-carrier_transmission): Case II : Amplitude modulation with carrier: Now...

Very clear. Thanks!

In general I read that: R_m =\frac{l}{\mu A} But considering for example the following transformer: I don't understand why the lengths taken from the sketch by the solution's procedure are the following: For the right and left part resistance: R_r = R_l = \frac{(\frac{1}{2} + \frac{1}{2}...

How many trees are in a graph if the number of nodes and the number of branches (or meshes) is given? I refer to the trees which has to "walk" through the nodes along the given branches (so no tree between 2 nodes without a connecting branch between them)

Thanks for all the answers :)

Homework Statement Homework Equations I think it will make use of tables... The Attempt at a Solution Can someone tell me the solution step by step of this problem? Help me please :( Thanks in advance..

Homework Statement Homework Equations FBD and all forces and moments = 0 The Attempt at a Solution Sketched in the image. So, I don't know how to go on with my analysis of the load, since I can't determine the reaction forces. Can someone please help me? Thanks in advance!

Is it correct what I did till now?

My problem is, that I don't understand what keep the rigid lever and the flat bar together..
