Answer:

Explanation:

The refractive index of the suspected glass can be known by using the backe- line method. This process takes place in a petrographic microscope. In this method an oil comparable to the refractive index of the glass is used. At a point when the refractive index of the glass becomes equal to that of the oil in which it is immersed the yellow line under the observation of the plane polarized light gets disappeared. This method can be used to identify the refractive index of the suspect glass and comparing it with the source of origin or sample glass.

Janis earns $7.00 per hour at Pizza King. After 6 months, her hourly pay of pay increased to $7.70 per hour. What is the percent

suter [353]

Answer: 10%

Explanation:

Given: Previous Hourly pay= $7.00

Current Hourly pay = $7.70

Increase in hourly pay = Current Hourly pay - Previous Hourly pay

= $7.70- $7.00

= $0.70

Now, the percent increase in her hourly rate of pay will be :

$\dfrac{\text{Increase in hourly pay}}{\text{Previous Hourly pay}}\times100\%\\\\=\dfrac{0.70}{7}\times100\%\\\\=\dfrac{1}{10}\times100\%\\\\=10\%$

Hence, the percent increase in her hourly rate of pay = 10%

A population of mice has black or brown hair. The gene for black hair color (B) is dominant over brown (b). If 16% of the mice a

amm1812

B = 0.4

b = 0.6

Explanation:

From the question we derive that;

BB = 16%

Bb = 24%

The gene frequency for BB = 16/100 = 0.16

To find allelic frequency of B;

B = √0.16 = 0.4

Remember Hardy Weinberg rule that all allelic frequencies of a gene must sum up to 1;

p + q = 1

If p = 0.4

q = 1 – 0.4 = 0.6

b = 0.6
