Hi how can the answere of 4,19 * 10^3 *1,75 *86 be writen like this "6,3*10^2" ?
+130466 4,19 * 10^3 *1,75 *86 = 630.595 x 10^3
In scientific notation this would be written as 6.30595 x 10^5
CPhill.. im really impressed!
Just started a new school and im kinda not that good when it comes to math in general. But im trying my best to learn
more. The question you gave me just made alot of sence and i totaly understand why it's so! :D
The reason why i asked this is that we have a few exercises that we can use to get better and math is involved.
The question is basically
How much energy do you use to heat up 1,75 kg water from 6c(celcius) to 92c(celcius)
specific heat capacity for water is 4,19*10^3. So if i follow this E=c*m*delta T ( Energy = specific heat capacity for water * mass*temperature change) ?=4,19*10^3*1,75*86
The answere is: 6,3*10^2kJ
I have no idea how it became 6,3*10^2 and not 10^5 ?
