Answer:

The distance traveled in 1 year is: 3.143*10^{16}ft

Explanation:

Given

s = 982,080,000 ft/s --- speed

t = 32,000,000 s --- time

Required

The distance traveled

This is calculated as:

Speed = \frac{Distance}{Time}

So, we have:

Distance = Speed * Time

This gives:

Distance = 982,080,000 ft/s * 32,000,000 s

Distance = 982,080,000  * 32,000,000ft

Distance = 3.143*10^{16}ft -- approximated

<h2>Answers:</h2><h2 /><h2>a) Arrow B</h2><h2>b) Arrow E</h2>

Explanation:

Refraction is a phenomenon in which a wave (the light in this case) bends or changes its direction <u>when passing through a medium with a refractive index different from the other medium.</u>  Where the Refractive index is a number that describes how fast light propagates through a medium or material.  

According to this, if we observe the rays  A an D passing throgh the biconcave lens, we will have two mediums:

1) The air

2)The material of the biconcave lens

This two mediums have different refractive indexes, hence the rays will change the direction.

-For the incident ray A, the corresponding refractive ray is B, because is the ray that bends after passing throgh the lens

-For the incident ray D, the refracted ray is E following the same principle.

What is simple machine<br>​
notsponge [240]

Answer:

ϟ \huge{ \boxed{ \purple{ \text{Simple \: Machine}}}}

⤥ We use different types of devices in our life to make our work easier. A spade is used to dig , a broom is used to sweep , a hammer is used to pass a nail on the wall and a plank is used to drag a load up to a certain height. All these simple things or devices , which are used in our daily life are called simple machines. Such simple machines do not do our work themselves but we have to use force on them to work with them. Thus , Simple machines are those tools or devices which make our work easier and convenient to do in the direction of force.

Hope I helped ! ッ

Have a wonderful day / night ♡

An amateur astronomer grinds a double convex lens whose surfaces have radii of curvature of 40 cm and 60 cm. The glass has an in
DedPeter [7]

Answer:

44.4cm

Explanation:

glass has an index of refraction .n = 1.54

radii of curvature of 40 cm R1 = 40 by

radii of curvature of 600 cm R2 = 60

Now, by lens maker formula

1/f = (n - 1) (1/R1 - 1/R2)

Putting in the given values for n = 1.54 , we get f = 22.2

\frac{1}{f} = (1.54 -1) (\frac{1}{40cm} -\frac{1}{(-60cm)} )

\frac{1}{f} = 0.0225

f = 1 / 0.0225

f = 44.4cm

so, focal length in air will be  = 44.4 cm
