A steel wire in a piano has a length of 0.6000 m and a mass of 3.600 10-3 kg. To what tension must this wire be stretched in order that the fundamental vibration correspond to middle C (fC= 261.6 Hz on the chromatic musical scale)?
According to their frequencies, waves are separated into three categories: (1) Audible or sound waves : Range 20 Hz to 20 KHz. These are formed by vibrating bodies like as voc
Do you know about optical rotation?
Battery powered vehicles Used DC series motors are the first choice. Recently AC motors with frequency changers are being considered.

Elastic collision : A collision is known as elastic when kinetic energy is also conserved along with the linear momentum. There is no transformation or loss of kinetic energy in th
Kohlrausch's law (F. Kohlrausch): If a salt is dissolved into water, the conductivity of the solution is the total of two values one based on the positive ions & the other dep
Must all illuminator have forced ventilation? Usually yes, the exception being which with a massive construction that dissipate heat by transfer or radiation.
These resistors change their resistance with variations of incident light energy. MANUFACTURING: Cadmium sulphide is obtained in a highly pure state. By adding special m
Q. In the given circuit, calculate the potential differences across each resistor Solution : i) R s = R 1 + R 2 + R 3 = 10Ω ii) Current in circuit I = V/R s
