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
A constant force of 10N is applied perpendicular to rod placed on 2 parallel rails .If the rod is having a resistance 10ohm but rails have zero resistance then maximum speed of rod
Illustrate the mechanism of piezoelectric effect? Mechanism of Piezoelectric effect: Piezoelectric and inverse piezoelectric consequences are only exhibited through certain
If you "bow" a string on a violin you hear a note with a frequency of 1020 Hz. If the length of the string is about 40cm, what is the "wave" on the string? Draw a diagram to show
a) Heat produced or absorbed at a junction is proportional to the current by the junction. b) This effect is produced when current is passed by junction of suitable materials.
The Time Base Control 3 Shows the effect of changing the time base control on the display when there is an input voltage varying in time when the frequency of the voltage is hi
THE BASIC CAPACITOR If we have two metal plates close together, but separated by an insulator or dielectric (which could be air) and we apply a voltage across them, electrons a
DIMENSION of Newton DIMENSION ? The dimension of force is [MLT -2 ]
Can you please, explain what is ''n'' in this equation: Q=ne?
TA=300 TB=400 rA= rA=6.3(10)^12
Phenomenon of resonance At resonance, rapid transfer of energy takes place resulting louder sound (booming sound). If two bodies having same natural frequency is placed side b
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)
