Answer:
TA is greater than TB
> 
Explanation:
Specific heat at constant pressure
is greater than specific heat at constant volume
.Therefore for given amount of supplied heat,increase in temperature at constant volume is greater than increase in temperature at constant pressure
Hence
TA is greater than TB

Unit lb mean pound. Which equals to about 0.45 kilograms(kg) /4536 grams,while 1kg equals to about 2.2lb.
Hope it helps!
To solve this problem it is necessary to apply the concepts related to Faraday's law and the induced emf.
By definition the induced electromotive force is defined as


Where,
Electric field
B = Magnetic Field
A = Area
At the theory the magnetic field is defined as,

Where,
N = Number of loops
I = current
Permeability constant
We know also that the cross sectional area, is the area from a circle, and the length is equal to the perimeter then
A = \pi r^2
l = 2\pi r
Replacing at the previous equation we have that

Where,
R = Radius of the solenoid
r = The distance from the axis
Re-arrange to find the current in function of time,

Replacing our values we have


Answer:
Explanation:
Given
mass of ethanol 
mass of aluminium cup 
both are at an initial temperature of 
specific heat of ethanol 
specific heat of aluminium 
specific heat of ice 
specific heat of water 
Latent heat of fusion 
suppose m is the mass of ice added
Heat loss by Al cup and ethanol after
is reached

Heat gained by ice such that ice is melted and reached a temperature of 

Comparing 1 and 2 we get

Thus 23.65 gm of ice is added
