18. A circuit contains a 10 ohm resistor, a 50 ohm resistor, and an 80 ohm resistor connected in parallel. If you test this circ
lutik1710 [3]

The equivalent resistance is D) 7.55 \Omega

Explanation:

The equivalent resistance of n resistors in parallel is given by the equation:

\frac{1}{R}=\frac{1}{R_1}+\frac{1}{R_2}+...+\frac{1}{R_n}

For three resistors such as in this problem, the equation becomes

\frac{1}{R}=\frac{1}{R_1}+\frac{1}{R_2}+\frac{1}{R_3}

where we have the following:

R_1 = 10 \Omega is the resistance of the 1st resistor

R_2 = 50 \Omega is the resistance of the 2nd resistor

R_3 = 80 \Omega is the resistance of the 3rd resistor

Substituting, we find the equivalent resistance:

\frac{1}{R}=\frac{1}{10}+\frac{1}{50}+\frac{1}{80}=0.133 \Omega^{-1}

R=\frac{1}{0.133}=7.55 \Omega

What is the function of eye lens of the human eye<br>​
Artyom0805 [142]

Answer:

Lens of the human Eye is a important and one of that most complex sense organ.

Explanation:

Lens of the human eye it helps that in visualizing light and color perception and objects , glance on the human eye structure and function.

Sense organs are much pretty similar to the camera they  help us see the objects clear.

A human eye is the 2.3 cm in diameter and all filled some fluid, and there are following parts in eye:-  cornea,  Retina , Lens ,Pupil , optic nerves.

cornea :- the cornea is the first transparent part of is called cornea, enters the light through the cornea.

Retina :-it is light sensitive layer that consists of nerve cells,then transmitted to the brain through nerves.

Lens:- behind the pupil there is a transparent structure called lens,it shape focus light on the retina.

Pupil:-it control the value of light that enters the human eye.

Optic nerves is are the two types :- (1) cones (2) Rods .

Rufina [12.5K]
A) Expanding. We know this because it has a similar effect with sound. When a car goes by the pitch gets deeper and deeper. It's because you're receiving less waves. Same thing for light but instead of a pitch it's light, and the farther spread the waves - the redder, the closer and more contracted - the bluer

The astronomer who first worked out the mathematical description of black hole event horizons was?
vovangra [49]

Karl Schwarzschild devised the first general relativity model that would adequately describe a black hole in 1916.

What is Black Hole?

A black hole is an area of spacetime with such intense gravitational pull that nothing can escape from it, not even light or other electromagnetic waves. According to general relativity theory, a compact enough mass can bend spacetime into a black hole. The event horizon is the line beyond which there is no escape.

Black holes were once thought to be a mathematical curiosity, but theoretical research in the 1960s revealed that they were actually a general prediction of general relativity.
