The refractive index n of transparent acrylic plastic (full name Poly(methyl methacrylate)) depends on the color (wavelength) of

the light passing through it. At wavelength 486.1 nm (blue, designated with letter F) -> nF=1.497, and at wavelength 656.3 nm (red, designated with letter C) -> nC=1.488. Two beams (one of each wavelength) are prepared to coincide, and enter the flat polished surface of an acrylic block at angle of 45 arc degree measured from the normal to the surface. What is the angle between the blue beam and the red beam in the acrylic block?

Yuliya22 [3333]

Answer:

The typical weight of a human heart is approximately 0.93 lbs.

Explanation:

Based on this,

the heart's weight constitutes about 0.5% of total body mass.

Total human weight = 185 lbs

Let the entire body weight be represented as w and the heart's weight as w_{h}.

We aim to determine the heart's weight for a human

Using the provided information

w_{h}=0.5\times w

Where, h = heart weight

w = human weight

w_{h}=\dfrac{0.5}{100}\times 185

w_{h}=0.93\ lbs

The final weight of a human heart is 0.93 lbs.

Jay collects eggs in a basket and weighs the basket. He graphed the relationship between the number of eggs
serg [3582]

Answer:

I'm having difficulty comprehending the figures you've presented, but I will attempt to address the inquiry.

Jay is gathering data on the weight of a basket in correlation to the number of eggs it holds.

For a single egg, he notes that the basket weighs w1

for two eggs, the basket weighs w2

and continues similarly.

In this context, a linear relationship can be established as:

Weight = number of eggs*k + b

Where k denotes the slope and b refers to the y-intercept.

k signifies the average weight of each egg, while b marks the initial weight of the basket.
