The length of the side of a cube (in cm) having a volume of 44.4 l is

As in question, the side of a cube having a volume of 44.4 L.

Now can also write, .

As        

So, we can write,    

Therefore, the length of the side of a cube root of

work: w = fd (given)

work done by chet   =50*1 = 50 j

work done by mika =40*2 = 80 j

work done by sara =30*1.5 = 45 j

work done by bill =60*0.5 = 30 j

students in order from the greatest amount of work done to the least is mika> chet> sara> bill

hence option (b) is correct.

d. platinum would have the greatest temperature increase because it has the lowest specific heat.
