in a physics experiment, 5.8 x 10^6 joules (j) of energy are converted into heat, and 1.3 x 10^5 joules of energy are lost as sound. what is the total energy dissipated? express your answer in scientific notation.

in a physics experiment, 5.8 x 10^6 joules (j) of energy are converted into heat, and 1.3 x 10^5 joules of energy are lost as sound. what is the total energy dissipated? express your answer in scientific notation.

Answer

Explanation:

Step1: Convert a number to same exponent

Convert $1.3\times 10^{5}$ to a number with exponent 6. $1.3\times 10^{5}=0.13\times 10^{6}$.

Step2: Add the two numbers

Add the energy converted to heat and the energy lost as sound. $(5.8 + 0.13)\times 10^{6}$. $5.8+0.13 = 5.93$, so the result is $5.93\times 10^{6}$ joules.

Answer:

$5.93\times 10^{6}$ joules
