How do I convert 498.82 cg to mg
mezya [45]
<span><u><em>Answer:</em></u>
498.82 cg is equivalent to 4988.2 mg

<u><em>Explanation:</em></u>
cg stands form centigrams
mg stands for milligrams

From the standards of conversion, to convert from centi to milli, we multiply the amount ny 10

<u>This means that:</u>
1 centigram = 10 milligram

To convert 498.82 cg to mg, all we have to do is <u>cross multiplication</u> as follows:
1 cg ..................> 10 mg
498.82 cg .........> ?? mg

498.82 cg = </span>\frac{498.82*10}{1}<span> = 4988.2 mg

Hope this helps :)</span>

Consider that a ray of light is travelling from glass to water. The refractive index of water is 1.30 (i e n . ., 1.30 w = ) and
Bess [88]

Answer:

\theta_i=49.88^{\circ}

Explanation:

Total internal reflection can happen when light goes from a medium with higher refractive index (in this case, glass) to a medium with lower refractive index (in this case, water).

Snell's Law tells us that n_isin\theta_i=n_rsin\theta_r, where the <em>i</em> stands for incident (in this case, glass) and the <em>r</em> for refracted (in this case, water). We want to know when \theta_r=90^{\circ}, that is, when n_isin\theta_i=n_r, and this happens when the incident angle is:

\theta_i=arcsin(\frac{n_r}{n_i})

Which for our values means:

\theta_i=arcsin(\frac{1.3}{1.7})=arcsin(0.76470588235)=49.88^{\circ}
