You transfer 20kJ20kJ of heat to a 4kg4kg block of iron and measure the temperature change of the iron. You apply 10kJ10kJ of heat to a second block of iron and find the temperature changes the same amount as for the first block. What is the mass of the second block

radial fractures in a piece of glass look most like which of the following?

a. spokes of a wheel

b. a circle

c. a zig zag

d. none of the above

the correct answer is a. spokes of a wheel

hope this (:

i had the same answer and put c. deflect randomly in multiple directions.   i looked it up on google and what i found was this;

scattering of light: by small particles and molecules in the atmosphere. different from reflection, where radiation is deflected in one direction, some particles and molecules found in the atmosphere have the ability to scatter solar radiation in all directions.

i know it's kinda annoying when you are just given a google article but this is why i think it is c.   i will try to let you know if i got it right.
