Charged antimatter particles are stored using electric and magnetic fields in near vacuum conditions. (Near-vacuum conditions can be created on Earth) Anti-hydrogen is stored by exploiting its magnetic properties. (While neutral, it still has spin magnetic moment. The storage is done using strong superconducting magnets.) Antiparticles are easier to store ...

The Large Hadron collider was closed for a year and more for an upgrade in energy from 7 to 14 TeV. They have started runs in the summer but there is nothing solidly announced, though there are some exciting hints , which need more statistics.

Recent particles, which were confirmed by CERN, are pentaquarks and also it has been observed that the Bs0 meson decay in 2 muons. Both of these though had been theoretically predicted long ago.

First, you should be aware that while normal racers need a good deal of downforce, it is used to increase tire friction and allow tighter turns. The Bloodhound, by contrast, is not intended to turn at all when at speed - ideally the driver would never turn the steering wheel. It just gets out on the track, gets up to speed, clocks the necessary distance, ...

A classic method of measuring focal length is with an interferometer rather than by imaging. This is because you can determine movement in conjugate points very precisely. For example, using the interferometer you can: Locate the front and back surfaces of the lens and measure their optical thickness by measuring the translation of the interferometer ...

No. That equation is only valid for the photoelectric effect. Since fluorescent lights use the concept of mercury spectrum emission (the emitted UV rays cause fluorescence on the tube's phosphor coating) and incandescent bulbs use the principle of thermal emission by Joule heating, the said equation won't work. Even then, considering that these incandescent ...

Here is a (partial?) list of new hadrons discovered at LHC experiments $\chi_b(3P)$: a $b\overline{b}$ bound state, discovered by ATLAS in 2011 $\Xi_b(5945)^0$: a $bsu$ bound state, discovered by CMS in 2012 $\Xi_b^\prime(5935)^-$ and $\Xi_b^\star(5955)^-$: $bsd$ bound states, discovered by LHCb in 2014 $P_c(4380)$ and $P_c(4450)$: $c\overline{c}uud$ ...

Power is voltage times current, either of which is relatively easy to control. If your accuracy requirement is not so tight that the change in resistance of the heating element matters, you can simply assume power is either proportional to the square of the voltage or the square of the current. For tighter control, you need to do the math. Generally you'd ...

I'm not sure I understand what you're asking exactly, but there are two effects you might be seeing: A coiled wire is longer than a straight wire that fits in the same space. Therefore it has higher resistance ($R=\rho\dfrac{l}{A}$) and so produces more heat from the same current flowing through it. A coiled wire can't cool itself as efficiently as a ...

You will find that the coil will heat up much more with an AC current than a DC one. This is because for an AC current the coil will dissipate heat because of self induction. The coil set up a magnetic field in its core, and Faraday law will tell you that the change in the field due to a change in the current will cause impedance in the circuit.

I would add a third reason to The Photon's and Paul's answers. The electrons in a current flow in a straight wire are bouncing permanently with the atoms and running zig zag. As The Photon pointed out, Th e wire has an ohmic resistance. The electrons in a flow in a coil beside the bouncing have to run in circles and this is clearly an acceleration. Due to ...

According to http://www.scienceinschool.org/2014/issue28/planck, All you need to calculate Planck's constant is Four LEDs emitting coloured light – one each of red, orange, green and blue. Choose LEDs w Four LEDs emitting coloured light – one each of red, orange, green and blue. Choose LEDs with a clear, colourless casing surrounding the LED, so that ...

Experiments in Modern Physics, by Adrian C. Melissinos and Jim Napolitano The author details the most fundamental experiments in modern physics, performing an integration with matlab for data analysis and display This book is accessible to beginning undergrad students, yet still theoretically rich enough for advanced experimental practice. It can be used ...

The displacement of 7.44° is clearly wrong. It is inconceivable that a torsion pendulum with a period of around 50 - 100 seconds could be displaced by such a large amount through the attraction of a couple of 2 kg masses. I have to conclude that other factors (air currents?), not gravity, were the cause of the displacement you observed. You really need to ...
