5 পয়সা এবং 50 পয়সাকে টকায় লেখ
পয়সাকে টাকায় রুপান্তর করতে গেলে, পয়সাকে 100 দিয়ে ভাগ করতে হবে।
5 পয়সা
=(5/100) টাকা
=0.05 টাকা
সুতরাং, 5 পয়সা = 0.05 টাকা
50 পয়সা
=(50/100) টাকা
=0.5 টাকা
অতএব, 5 পয়সা = 0.05 টাকা এবং 50 পয়সা=0.5 টাকা।
FUNCTION OF BASS, TREBLE, VOLUME OPTION IN AN AMPLIFIER
Bass and Treble options are used to regulate the sound on the basis of frequency. Generally a audio amplifier has 3 main controlling options. (i) Volume or Master (ii) Bass (iii) Treble Volume : When we increase Volume the loudness of the audio is increased. In frequency level, the amplitude of all the frequencies are increased. Similarly, when we decrease Volume, the loudness is decreased i.e. amplitude of all the frequencies are decreased. Bass : When we increase Bass, the loudness of only lower frequencies are increased i.e. amplitude of the lower frequencies are increased. When we decrease Bass, the loudness of only lower frequencies are decreased i.e. amplitude of the lower frequencies are decreased. Treble : When we increase / decrease the Treble, the loudness of the sound of only higher frequencies are increased / decreased. Now the main questions is that what do lower and higher frequencies mean ? We know that human beings able to h...
