The food you eat every day provides the nutrients you need to survive. These food components include the macronutrients – protein, carbohydrate and fat – that offer calories as well as play specific roles in maintaining your health. Micronutrients, such as vitamins and minerals, don’t act as an energy source but do serve a variety of critical functions to ensure your body operates as optimally as possible.

Penghitungan intensitas suara dengan satuan desibel menggunakan rumus "10 log x" yang berarti setiap 10 desibel akan menghasilnya bunyi dengan intensitas 10x lipat, 20 desibel = 100 kali lipat, dan seterusnya. Rumus yang dipakai untuk soal ini adalah:
<span>TI2 = TI1 − 10 log ( <span>r2</span>/<span>r1</span> )<span>2
</span></span>Intensitas suara 2= intensitas suara 1 + 10 log (lokasi 2/lokasi 1)
Intensitas suara 2= 50dB + 10 log 50m/3m = 50db + 10 log 16.7= 62.21dB
