Define mica capacitor?

When might it be necessary to use a 2 µF polyester capacitor rather than a 2 µF electrolytic capacitor?

when high voltages are present because the voltage rating of polyester (polyethylene terephthalate) capacitor is high as well as electrolytic capacitor will destroy if the voltage increases from nominal voltage and cause short circuit conditions.

What is the difference between framed and unframed?

Unframed E1, you will be able to use the full bandwidth of the circuit of 2048 kpbs. Normally, for various reasons, this mode is not given to customers by telco.

Costly service

Framed E1 ,you will be able to use 1984Kbps only from 2048Kbps where timeslot 0 is reserved for sync and signaling purposes.

Less costly when compared with Unframed.

How do you iron polyester ties?

Cover the tie with a cotton cloth before ironing. Test the iron on plain cloth to check that it is not too hot. The iron should be kept a low temperature and must not exceed 140 degree Celsius. It is best to avoid ironing a tie as this may damage the fabric or make it look too flat.

What is the difference between a TH350 and TH400 Trans?

The th400 is a much stronger transmission meant for heavy duty use while the th350 is meant for normal use.

What is the difference between Axis 1 and Axis 2 disorders?

Axis I disorders are predominantly mood disorders while Axis II disorders are personality disorders.

How long does it take for netting to decompose?

This depends on the material the net is made from. A nylon net can last indefinitely while a natural fiber rope will eventually decompose. Decomposition will depend on water temperature and organisms in the water.

What is the difference between a mullion and a muntin?

A mullion is the bar or bars in the middle of a window. A muntin is the bar on the outside of the window. == I have heard much debate about this question this is how I understand it. A window sash is made of the stiles, rails and muntins. The rails being the top and bottom and the stiles the sides that ride in the jamb, the muntins are the thin pieces of wood that divide the sash into lites. There is a small lip on the back of the muntin that the panes of glass are bedded to then glazed. Mullions are the vertical trim pieces that divide the windows in a ganged window, for instance a triple window would have two mullions separating the middle window from the outer windows.

What is the difference between isostatic anomaly and Bouguer anomaly?

Bouguer anomaly - This anomaly corrects for the gravitational attraction of the rock above sea level.

This correction is done after Free Air correction which accounts to the height of the measurements above sea level.

The simple Bouguer correction is calculated assuming that the rock above sea level is a slab of uniform thickness and density (generally 2.67g/cc for land data, 2.0 or 2.2 for marine data).

This density is called reduction density, and can be calculated with the Nettleton method which states that the optimum density is the one with the least correlation with topography.

In case of rough terrains a Complete Bouguer Correction is needed which accounts for topographic lows and highs (Terrain Correction).

The Bouguer anomaly is best for looking at local and regional gravity anomalies.

Isostatic anomaly - The isostatic anomaly accounts for low density roots needed to balance the topography and can be derived using either Pratt's or Airy's hypothesis and corresponds to the deviation of the crustal structure from floating statically in the upper mantle.

The isostatic anomaly improves on the other 2 anomaly models by taking into consideration the root structure under the crustal structure (mountain range) but that is also a problem as we often don't know what the root looks like.

This type of anomaly is best for the study of the sedimentary sequence, while it is not appropriate for deep crustal studies.

What is the difference between a layer 2 and a layer 3 switch?

The difference between Layer 2 and Layer 3 switching is the type of information inside the frame that is used to determine the correct output interface. With Layer 2 switching, frames are switched based on MAC address information. With Layer 3 switching, frames are switched based on network-layer information.

What is the difference between DIT DIF?

DIT is decimation in time. The input signal must already be available in bit-reversed format. This is the top-down approach where the entire time signal is split into two halve, then each half into again two more halves, etc.

DIF is decimation in frequency. Input is in normal order. The output is in bit-revered order. This is a bottom-up approach.
