15-02-2016 13:47:00 +0000Good day All,
My name is Sunday and I'll be available for the next hour or so to help answer any questions you may have.
I am the tutor of the physics lessons on the Jambite app.
Ask your question as a comment and I'll try to answer as many people as possible.
Thanks.

Sir,in a resonance tube experiment performed with a vibrating turning fork of frequency 300Hz,the length of the air column at first resonance is 30cm.The velocity of sound in Air is?

A simple microscope forms an image twice the size of the object. If the focal length of the lens of the microscope is 20m,how far is the object from the lens? A.10m B.20m C.30m D.40m E.60m

simple sense it means " the quality in a sound of being deep, full, and reverberating"

@Deborah Uchechi. Current electricity as the name goes is analogous to Electric Current. So Electric current is defined to be the rate at which charge flows. Represented as current I= Q/t, Were Q = charge and t = time

@Ebuka Kingsley. recall that velocity of sound = wavelength times frequency, resonance occurr at intervals of length lahmda/4 for first resonance. so lahmda = wave length = 4 times air colunm length of the first resonance = 4&time;30 = 120cm. = 1.2m so velocity v = 300 × 1.2 = 360m/s

My problem in physics is calculations... Please is there any short cut that make me so easy to understand calculations? THANKS

@Adesewa Rufai magnets can be demagnetized by placing them in a coil connected to an alternating electric current source. Hammering or heating the magnet may also cause a loss of magnetization in a steel bar magnets.
