What happens to capacitors at low frequencies? At very low frequencies, such as 1Hz our 220nF capacitor has a high capacitive reactance value of approx 723.3KΩ (giving the effect of an open circuit). At very high frequencies such as 1Mhz the capacitor has a low capacitive reactance value of just 0.72Ω (giving the effect of […]
What can a firewall not prevent?
What can a firewall not prevent? Users not going through the firewall: A firewall can only restrict connections that go through it. It cannot protect you from people who can go around the firewall, for example, through a dial-up server behind the firewall. It also cannot prevent an internal intruder from hacking an internal system. […]
Is it OK to run anaerobic?
Can light be a reference frame?
Can light be a reference frame? In all reference frames that actually exist, light travels through space and time in a normal way just like any other object. According to Special Relativity, as a frame goes faster, it shortens more in the direction of motion, relative to the stationary observer. How did Einstein know that […]
What is the electric potential if the electric field is zero?
What is the electric potential if the electric field is zero? If the electric field is zero, then the potential has no gradient i.e.: the potential is equal across space. But potential is always measured relative to a baseline, so it can therefore be considered as zero. Can electric potential at a point be zero […]
What is the uncertainty in the mass of a muon?
What is the uncertainty in the mass of a muon? muon mass Standard uncertainty 0.000 000 042 x 10-28 kg Relative standard uncertainty 2.2 x 10-8 Concise form 1.883 531 627(42) x 10-28 kg Click here for correlation coefficient of this constant with other constants What is produced when a muon decays? The muon is […]
Is walking a push or pull?
How do bones muscles and joints work together?
How do bones muscles and joints work together? Muscles can pull bones, but they can’t push them back to the original position. So they work in pairs of flexors and extensors. The flexor contracts to bend a limb at a joint. Then, when the movement is completed, the flexor relaxes and the extensor contracts to […]
What is the charge on the other plate of the capacitor?
What is the charge on the other plate of the capacitor? Capacitors do not store charge. Capacitors actually store an imbalance of charge. If one plate of a capacitor has 1 coulomb of charge stored on it, the other plate will have −1 coulomb, making the total charge (added up across both plates) zero. How […]
Which ocean has strongest currents?
Which ocean has strongest currents? Antarctic Circumpolar Current What happens if deep ocean currents stop? The ocean currents carry warmth from the tropics up to these places, which would no longer happen. If the currents were to stop completely, the average temperature of Europe would cool 5 to 10 degrees Celsius. There would also be […]
