Define about the Heat Loss?
An immersion heater of power J=500 W can be used to heat water in a bowl. After 2 minutes the temperature enhance from T1=85oC to T2=90°C. The heater is after that switched off for an additional minute and the temperature drops ΔT = 1°C. By estimation the mass of the water in the bowl and The thermal capacity of water c= 4.2 • 103j/kg K.
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
a car tyre is pumped up to 230 kPa. What is the volume of air at atmospheric pressure (100kPa) that must be pumped into a tyre that has a volume of 0.1 cubic meter?
A plane e-m wave goes along vertical downward direction. At a provided instant, the direction of E at a point is towards east. Find the direction of B?
a yellow lamp emits light with a wavelength of 6.00E-7 meters. Calculate the frequency of the yellow light.
Q. Three capacitors every of capacitance 3 pF are connected in parallel. Find effectual capacitance. The effectual capacitance Cp = C1 + C2 + C3 = 9 + 9 + 9 = 27 pF
First Law: It shows that the mass (m) of substance deposited at the cathode during electrolysis is directly proportional to the quantity of electricity (total charge q) passed by t
Amplitude: The maximum displacement of a body on either side of the mean position during simple harmonic motion is known as amplitude and it is shown by x.
Essential properties of the medium for wave propagation: (i) Elasticity: So that particle can return to their mean position, after having been disturbed. (ii) Inertia : So t
