Answer:

This question is incomplete but the completed is below

Which of the following is a risk of obesity?

A. Bone loss

B. Sleep apnea

C. Liver damage

D. Addiction

Explanation:

Obesity is a medical condition in which the body has accumulated excess body fats. This condition exposes the body to other medical complications/issues such as diabetes, atherosclerosis, cardiovascular diseases and in some forms of cancer.

Sleep apnae is a serious sleeping disorder that causes one to have an interrupted breathing pattern during sleep. Obesity can also cause this, as excess fat could disturb the windpipe or even the heart causing heavy and irregular breathing during sleep.

The left face of a biconvex lens has a radius of curvature of magnitude 11.7 cm, and the right face has a radius of curvature of
SIZIF [17.4K]

Answer:

Explanation:

R1 = + 11.7 cm

R2 = - 18.7 cm

n = 1.52

(a) Use lens maker formula

\frac{1}{f}=\left ( n-1 \right )\left ( \frac{1}{R_{1}}-\frac{1}{R_{2}} \right )

\frac{1}{f}=\left ( 1.52-1 \right )\left ( \frac{1}{11.7}}+\frac{1}{18.7} \right )

\frac{1}{f}=\frac{0.52\times 30.4}{218.79}

f = 13.84 cm

(b)

R1 = + 18.7 cm

R2 = - 11.7 cm

n = 1.52

(a) Use lens maker formula

\frac{1}{f}=\left ( n-1 \right )\left ( \frac{1}{R_{1}}-\frac{1}{R_{2}} \right )

\frac{1}{f}=\left ( 1.52-1 \right )\left ( \frac{1}{18.7}}+\frac{1}{11.7} \right )

\frac{1}{f}=\frac{0.52\times 30.4}{218.79}

f = 13.84 cm

An ideal photo-diode of unit quantum efficiency, at room temperature, is illuminated with 8 mW of radiation at 0.65 µm wavelengt
nadya68 [22]

Answer:

I = 4.189 mA    V = 0.338 V

Explanation:

In order to do this, we need to apply the following expression:

I = Is[exp^(qV/kT) - 1]   (1)

However, as the junction of the diode is illuminated, the above expression changes to:

I = Iopt + Is[exp^(qV/kT) - 1]   (2)

Now, as the shunt resistance becomes infinite while the current becomes zero, we can say that the leakage current is small, and so:

I ≅ Iopt

Therefore:

I ≅ I₀Aλq / hc  (3)

Where:

I₀A = Area of diode (radiation)

λ: wavelength

q: electron charge (1.6x10⁻¹⁹ C)

h: Planck constant (6.62x10⁻³⁴ m² kg/s)

c: speed of light (3x10⁸ m/s)

Replacing all these values, we can get the current:

I = (8x10⁻³) * (0.65x10⁻⁶) * (1.6x10⁻¹⁹) / (6.62x10⁻³⁴) * (3x10⁸)

I = 4.189x10⁻³ A or 4.189 mA

Now that we have the current, we just need to replace this value into the expression (2) and solve for the voltage:

I = Is[exp^(qV/kT) - 1]

k: boltzman constant (1.38x10⁻²³ J/K)

4.189x10⁻³ = 9x10⁻⁹ [exp(1.6x10⁻¹⁹ V / 1.38x10⁻²³ * 300) - 1]

4.189x10⁻³ / 9x10⁻⁹ = [exp(38.65V) - 1]

465,444.44 + 1  = exp(38.65V)

ln(465,445.44) = 38.65V

13.0508 = 38.65V

V = 0.338 V

A storm 10.0 km in diameter has wind speeds of 10.0 m/s. What is its angular velocity in radians per second
Aloiza [94]

Answer:

The value is w= 2*10^{-3} \  rad/s

Explanation:

From the question we are told that

  The diameter of the storm is  d =  10.0 \  km  =  10 000 \  m

   The wind speed is  v  =  10.0 \  m/s

   

Generally the radius is mathematically represented as

       r =  \frac{d}{2}

=>  r =  \frac{10000}{2}

=>    r =  5000 \ m

Generally the angular velocity is mathematically represented as  

        w= \frac{v}{r}

=>     w= \frac{10}{5000}

=>     w= 2*10^{-3} \  rad/s

PLEASE HELP 15 POINTSexplain properties and importance of light and how it separates into colors
Inessa05 [86]

Answer:

It is not a property of light. It is your eyes and brain.

Specifically, the three kinds of cone cells in our eye that are sensitive to different ranges of the electromagnetic spectrum. The fact that there are three means that color is three dimensional, and is the reason the pure colors form a circle even though the spectrum of wavelengths is linear.

Visible light is part of the electromagnetic spectrum; light waves of different frequencies and wavelengths are distinguished as colors by the human eye. A prism can separate the colors of white light (dispersion) because different frequencies of light have different refractive indices for a given material.
