I love Music, like it's the only subject i enjoy in school but don't know what career to pursue using that skill. Any ideas?

If music is what you love, go for it. Keep practicing and get yourself involved with music placements and apprenticeships if possible. That way it will allow you to network with others in the field you enjoy! If you end up changing your mind, you can always keep it as a close hobby and when it comes to CV’s and Personal statements for university, you can put that in to show how much of a well rounded person you are! Hope this helps!

I'm doing my Physics homework and I have a quick question, What is elastic energy and how is it different to kinetic energy?

To understand this, let's look into the atomistic scale of a material. Here you have an array of atoms with the material. Each of the atoms is connected with one another through intramolecular forces (such as ionic bonds and covalent bonds). Now if you stretch the material by applying a uniaxial tensile force, this will stretch the bonds within the material. As a result, some form of energy is stored within the materials as work is done. When you release uniaxial force applied on the material, these bonds will be unstretched and energy will be released. We call this as elastic potential energy. And if you plot out the extension-force curve of this material, the area under the linear-elastic regime of the material is the elastic potential energy. And it is given by U=1/2Fx, where U is the elastic potential energy, F is the force applied and x is the extension of the material. Kinetic energy is acquired when a body of mass is moved with a certain velocity. And this this given by E=1/2mv^2.

What kind of work experience can you get for psychology?

Well it depends on what field your looking to go into. Psychology branches off into many different sectors but work experience for psychology would mainly come from working in clinical based environments. But to be honest, universities will look for your ability to conduct a study and how well you can approach a problem. That’s my tip for you. Hope it helps!

What is better, an apprenticeship or going to college?

Interesting question! There is no correct answer to this but it really depends on what you feel is appropriate for your future. Don’t get me wrong, both can get you into university(if you want to)! College will provide you with all the fundamental knowledge you need for your select subject. On the other hand, apprenticeships are good for preparing you for that work field as it give you all the necessary training you require for that specific field, and maybe even a job placement! Sorry this isn’t the best of answers but I hope it helps!

What is the difference between potential difference and current?

Current: A flow of charges. They might be electrons, protons, ionized particles or any other form of charges. Potential difference: This is a measurement of difference in amount of unit charge densities between two places. Potentially different charges in two different places creates a flow of charges between two places if there is a path, a current.
