Well yeah I can kind of explain the first part too - albeit in a un-professional way. But for the remaining parts, I was like WTH coz I've never dealt with electrostatic questions of this length.
The guide says:
One thing about CIE Physics is that it deals with rather narrow topics and...
Before I go about trying to futilly solve the question, is this thing beyond a CIE A-Lv physics student's reach or not? Any comments on the difficulty of the question, and perhaps the reading material which you would recommend before I attempt the question?
Thank you.
You're right. The guide didn't mention anything about a variation with height at ten times the height too. Thanks. Will solve it now.
p = (density)(rms square speed)/3 = (density)(temperature)/3
(using the proportion that rms speed is proportional to temperature)
p = 6.67E-12
But the...
Bromine gas at atmospheric pressure and room temperature has a density of 6.4 kg/m3. An approximate r.m.s. speed of bromine molecules is 216.5 m/s.
Experiments show that bromine molecules take about 500s to diffuse 0.1m in air. This low speed compared with the r.m.s. speed can be attributed...
At an altitude of about 100km above the Earth's surface, the density and temperature of the atmosphere are about 10^-14 kg/m^3 and 2000K, respectively. At this altitude, the major constituent of the atmosphere is atomic oxygen. Use this information to estimate the pressure of the atmosphere at...
By considering the forces acting on B by masses A and B, I am able to come up with the formula F=k(y+z). However by doing that I am ignoring the forces on the right, and that the formula I obtained at the end is divided by a factor of surd 2. What am I doing wrong over here?
Can somebody please...
Two cylinders A and C of equal volume V contain the same ideal gas at temperature T and at pressures 2p and p respectively. A valve connecting the two cylinders is opened slightly and as the gas leaks from A to B, the pressure in A is maintained at 2p by pushing in a piston. The process is...
A vessel is divided into two parts of equal volume by a partition in which there is a very small hole. Initially, each part contains gas at 300K and a low pressure, p. One part of the vessel is now heated to 600K while the other is maintained at 300K. If a steady state is established when the...
An evacuated cubical box of side a is constructed with perfectly reflecting interior surfaces; initially, it is dark inside. A small window is opened to allow light of frequency f to enter the container and is also closed again when the box contains N photons. Suggest what might happen if the...
