Energy is transferred in a one direction only.
Example : Wave propagating in a stretched string.
why The magnitude of known potential difference must be greater than the value of unknown potential difference to be measured.
initial position time the vibration mean time time period of the bob t time
99 ml of H 2 O is initially at room temperature (20.0 o C). A chilled steel rod at 2.0 o C is placed in the water. If the final temperature of the system is 18.7 o C, what is th
Q. The kinetic energy of an electron 120 eV. Compute the de Broglie wavelength of electron. λ = h / √2mE λ = 6.626 X 10 -34 / √ 2 X 9.1 X 10 -31 X 120 X 1.6 X 10 -19
Factors which are affect velocity of sound in gaseous medium is (1) Effect of density (2) Effect of pressure (3) Effect of temperature : (4) Effect of humidity
a balloon is filled with 100 kg of helium, and that the velocity is 2.0 m / s what is the external kinetic energy?
A section through a magnetic circuit of uniform cross-sectional area 2cm 2 is shown in Figure. The cast steel core has a mean length of 25cm. The air gap is 1mm wide and the
How is energy transformed in windmills? Essentially what occurs is that as the energy from the wind rotates the vanes of the mill, coils of wire move inside a permanent magnet
A standing wave is formed on a tightly stretched string. The distance between a node and an antinode is: w) 1/8 wavelength x) 1/4 wavelength y) 1/2 wavelength
