What are multistranded fibers?
Multistranded optics is narrow walled tubes of transparent material that housing a number of smaller solid core fibers. These inner fibers are, usually 0,75mm in diameter and numbered from ten or less to some hundred, depending upon the last use and diameter of the optic.
a closed organ pipe resonates with frequency 6hz and an open organ pipe resonates with frequency 12Hz. if the two organ pipes are joined to form a single organ pipe then it will re
The most probable radius (in pm) for finding the electron He + is: (1) 0.0 (2) 52.9 (3) 26.5 (4) 105.8 Ans: (c)26.5
Eddy current loss is proportional to the (A) Frequency. (B) Square of the frequency. (C) Cube of the frequency. (D) Square-root of the frequency.
A single-phase, 50Hz transformer has 40 primary turns and 520 secondary turns. The cross-sectional area of the core is 270cm 2 . When the primary winding is connected to a 3
