Answer:
Explanation:
Let mass of ice required is m kg
Heat gained by ice to attain zero degree
= m x 14.1 x 2100
= 29610m J
Heat gained by ice to melt = m x 3.34 x 10⁵ J
= 334000m J
Heat gained by water at zero degree to warm up to 27 degree
m x 4190 x 27 =113130 J
Total heat gained = 476740m J
Heat lost by hot water to cool up to 27 degree
.24 x 4190 x ( 75.8 - 27 )
= 49073.28 J
Heat lost = heat gained
476740 m = 49073.28
m = 49073.28/476740 kg
=102.93 gm
Answer:

Explanation:
C = 9 micro farad = 9 x 10^-6 F
L = 16 H
f = 60 Hz
Vrms = 116 V


XL = 6028.8 ohm


Xc = 294.88 ohm
Let Z be the impedance of the circuit.


Z = 6036 ohm


Irms = 0.0192 A
Irms = 19.2 mA
