What is a rope-shaped tornado?
A rope-shaped tornado is a narrow tornado with a rope-like appearance. If a tornado is rope-shaped, that often means it is weak or starting to dissipate.
How can the magnitude to flux conversion be accurately calculated for astronomical observations?
The magnitude to flux conversion for astronomical observations can be accurately calculated using the formula: Flux = F0 * 10^(-0.4 * magnitude), where F0 is a reference flux value. This formula allows astronomers to convert the brightness of an object (magnitude) into its corresponding flux measurement.
What is fluxes in astronomy?
Definition: flux: A measure of the amount of energy given off by an astronomical object over a fixed amount of time and area. Because the energy is measured per time and area, flux measurements make it easy for astronomers to compare the relative energy output of objects with very different sizes or ages
How does burning rope tell time?
First. You take a lighter. And burn the end of a rope. And you count the seconds it takes to burn the piece of rope. Let's say it took 10 seconds. So after you count the 10 seconds, you know that 10 seconds have passed.
Why is rope important if you are stuck on the moon?
Rope can be useful on the moon for tethering to a spacecraft or to other astronauts to prevent drifting off in low gravity. Additionally, it can assist in securing equipment, tools, or samples in place. In emergency situations, rope can be used for rescue or navigation assistance.
Difference between flux linkage and flux leakage?
i) leakage flux is those flux which goes through the air and linkage flux is those flux whose go through the cell. ii)leakage flux is the loss at flux but linkage flu is warning flux. iii)leakage flux is cause of eddy current loss and linkage flux is case of copper loss.
What is leakage factor?
The Ratio of the total flux ( flux in iron path) to the useful flux (flux in air gap)
Difference between mutual flux and leakage flux?
when a current flow through the coil then flux produced around the coil . if the flux linked same produced coil only then the flux is said to be leakage flux. flux produced by one coil ,but linked with another coil then the flu is said to be mutual flux.
Difference between leakage flux and mutual flux?
when a current flow through the coil then flux produced around the coil . if the flux linked same produced coil only then the flux is said to be leakage flux. flux produced by one coil ,but linked with another coil then the flu is said to be mutual flux.

What are the two main types of flux?
Types of flux - Electric and Magnetic Flux. Electric field flux through a closed surface is equal to the change enclosed in the surface, or the rate of change of magnetic flux is equal to the induced voltage around the surface.
How flux is related to speed?
Flux is related to the speed of change in a physical quantity through the concept of flux density. Flux density is the amount of flux passing through a unit area per unit time. The faster the change in the physical quantity, the higher the flux density.
Air gap flux is termed as useful flux why?
Basically useful fluke is the flux that flows with in the magnetic circuit of an armature. That is why when there is an air gap the flux enters the armature which makes it useful flux! Hope that answers your question!
What are the differences between the natures of dc flux and ac flux?
dc flux is caused by dc current (flux and current are proportional), it is a constant value. Put an inductor (or transformer winding) across a battery and you will get dc flux. ac flux is caused by ac current (flux and current are proportional), it is a moving value, the flux moves with the current, typically cyclical but the waveform is arbitrary as long as we're moving.
In transformer core flux depends on voltage whereas leakage flux depends on current?
In a Transformer, Core flux is the difference of primary flux and Secondary flux which are opposite to each other in direction. There difference is equal to the no load flux at all loads. So, some of primary flux passes through the core and remaining becomes leakage flux (Because Secondary flux forces it to get out of the core). Same is the case with Secondary flux. Now, flux is directly proportional to Voltage and Current. When Current increases due to increased load (and voltage remains same): Then both primary and secondary flux increase. Because both of them increase, so there difference remains same. And all remaining flux is forced out. Hence leakage flux increases with current, but Core flux remains constant. When Primary Voltage is increased: Then only primary flux increases. So difference of this new increased primary flux and previous same secondary flux increases. Hence Core flux increases with voltage, But leakage flux does not. That's how In transformer core flux depends on voltage whereas leakage flux depends on current.
How do you calculate total flux when flux density and magnetic field strength has been?
once flux density is known multiply to it the area perpendicular to the flux lines . the product is the total flux passing through the area. If field strength is known , get the flux density by pultiplying to it the permeability of the medium. then flux can be obtained as above. from : govind Kunkolienker kunkolienker@yahoo.com
