Find the result of mixing 40 gm of ice at -10°C in 300 gm of water at 90°C in a copper calorimeter of mass 70 gm
​

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees. 

the ima (higher than 1m) will be greater than the ima with the height of 1m.
