When calculating the expansion of solids, can one only use Kelvin?
I had an assignment where the temperature change was given in degrees Celsius and on the board the same number was written just with K for Kelvin behind it.
Are 30C and 30K the same?
I am writing a physics test tomorrow and need many examples of a weight force
Task: For a uniformly accelerated movement from rest, a time of 0.93 seconds was measured for a distance of 60 centimeters. Use these values to calculate the final velocity of the body and the effective acceleration. Thanks
For question 2.1, you should calculate the lifting work required to raise the ship 24 meters. I just about managed that. For question 2.3, you should calculate the work required to raise the ship the same height. It should be the same as the lifting work (golden rule of mechanics), but in my case, it's…
Hello, I'm starting my physics degree in a few weeks and am wondering if I really should buy a laptop, even though I have a very capable desktop in my apartment. Laptops are expensive, and I'd rather invest my money elsewhere. thanks in advance.
What are they? I can't seem to find anything about them online… LG
I mean, the downward gravitational force isn't always the same as the tensile force pulling the body upward, is it? And I know a rope only absorbs tensile forces, but then the force has to be drawn on the cable drum and not on the rope, because the downward force is the gravitational force, and…
At temperaturedifferences does not matter because 1K difference is equal to 1°C difference. However, temperature differences are always written in Kelvin (K) – even if one has subtracted °C from one another.
People in countries that use Fahrenheit have made it much harder.
As temperatureDifference yes, as absolute temperature of course not.
No. The expansion of bodies does not matter at which temperatures water freezes or boils. Only the absolute temperature applies.
can I just make 10C in my clausur? Or do I have to convert?
as said – C is not the same as K. Of course you have to convert!
