If you stop cooling a resistor and stop current simultaneously then what happens to the temperature of the resistor in the next few moments? My question is actually about whether a computer CPU will continue to heat up at all when the computer is switched off (Stopping any power to the CPU, so...

I achieved a C, which as you say, is the most I can achieve on foundation tier. I was put in foundation tier in year 9 when my mathematical ability was much worse than it is nowadays. The higher tiers were already full during years 10 and 11 so there was quite a few people who missed out on...

I applied for my A level courses today and applied for Physics, Chemistry, Biology and Maths (M) However, I did foundation tier mathematics GCSE and I've been told that my application to do Maths A level is at the discretion of the head of the department. I have caught up on the higher tier...

I haven't studied quantum physics academically and I have no understanding of it mathematically so forgive me if my questions are strange, nonsensical or erroneous. For instance in the double slit experiment when we attempt to observe the object going through a slit then the diffraction...

I think that very few CEs work on sites or outdoors. My brother is a CE and he works in an office.

I'm not an aerospace engineer but I have done allot of research in the area because I'm also considering it as a prospective career; Since no one else has replied thus far, I feel like I can help you out. 1) AE's (Aerospace Engineers) design both aircraft and spacecraft . If you do decide to...

Sorry, i'll give a little more info. It's a molar mass (chemistry) calculation. In a scientific calculator then it gives me an answer with a variable as shown below: Number\ of\ moles = 0.05 * 0.025 = 1.25^{-03} Just I don't like working with scientific notations and would rather read...

Homework Statement I'm trying to convert something like 1.25^-03 into it's standard number composed of standard decimals using a calculator (0.0125) - if you know what I mean. Thanks.

Will either method give me a correct answer if I make sure to take the direction into account? I got an answer of 3 m/s for method 1 and -6.6 m/s for method 2. I don't see how it can be method 2 since truck A has a positive velocity and truck B would have had to go through truck A in order to...

I don't understand what you mean by +x. Do you mean I need to give a direction to the velocity?

I am trying to revise this subject but I am unsure which of the two method's I've used is the correct one. Can someone help me? Homework Statement two trucks travel towards each other. truck A has a velocity of 10 m/s and truck B has a velocity of 3 m/s. Truck A has a mass of 1000 kg and...

This is a question someone asked me today and it's bugging me allot. If the acceleration caused by gravity is greater than the speed of light at a black hole event horizon then does this mean that the matter is falling at faster than light speed?

Say I have a boat moving at 10 m/s south (160 degrees) ina river that is flowing at 3 m/s east (90 degrees) How would you calculate the resultant velocity in this instance?

I imagine this gets asked a lot but I'm looking for an in depth explanation since none of the others I've found are detailed enough. I understand that p = mv is not applicable near the speed of light and I think (but am unsure) that the correct equation to use is e = pc. Assuming that e =...

I'm not sure if the way I understand it is correct or if it is slightly inaccurate, so I will just write it as I understand it and hope you can all my point out my errors. As I understand it, there are 4 dimensions. 3 of space and 1 of time (first question. Is time actually considered an extra...
