2 Kg of ice at -20 degree C is mixed with 5Kg of water 20 degree C in an insulating vessel having negligible heat capacity. Calculate the final mass of water remaining in the comtainer. It is given thet the specific heats of water and ice are 1Kcal/kg/degree C and 0.5Kcal/kg/degree C while latent heat of fusion of ice is 80 kcal/kg
1. You are trying to observe a 500 Hz signal of amplitude 2 mV in the presence of an interfering 4.0 kHz signal also of amplitude 2mV. Use a MATLAB .m script to plot the waveform y
Noise: An undesirable and unpleasant sound that makes harmful effects on our auditory system is known as noise.
Suppose that we have a monochromatic non-diverging beam of x rays that are incident on a slab of Pb. Inside the Pb plate there are three apertures (openings) that allow the beam
Can you show mathematically that the total energy of a simple harmonic oscillator remains constant?
Question: The external surface of a short vertical segment of plastic pipe is hidden from view by wire wrapped around the pipe. Current flows clockwise as out looked from above
Total height of the gymnast just before falling back down is=(2+.3)=2.3m Energy gained at that point = m*g*h(m=mass, g=gravitational force, h=height) =55*9.8*2.3=1239.7 J
Quality: It is the characteristics of a sound by which we can distinguish among two sounds of the similar pitch and the loudness is known as quality of sound.
Que: Consider a capacitor containing of two flat metal plates of one and the same size. The plates are opposite each other and they are well-aligned with each other. The plates
initial acceleration rocket is 0.01t in upward dirction initioal velocity is 50ms-1 , what is the function for the velocity of the rocket?
Find the speed of the wave A copper wire, whose cross-sectional area is 1.1 x 10 -6 m 2 has a linear density of 7.0 x 10 -3 kg/m and is sturng between two walls. At the ambient
Apply the formula of mcT and at first calculate the amount of heat losed by water at 0 degree.the calculate the amount of heat gained by ice to go to 0 degree.now subtract the second from the first to get heat left for absorption.equate this heat to (mL)=latent heat ...and get the mass of new water formed.you will get it as 1 kg.hence the ans is 5+1=6 kg(ANS)
