Hello,


Your answer would be:


1) Solid, Liquid, Solid.


Explanation:

If you mean how they are made then it would be the first one because The product would begin as a crystal or rock and then melted down into glass with pressure and heat!


Brainliest!?!


Hope this helps!


Have a great day:)

Question:

Why is Glass useful for eyeglasses?

Answer:

Without the glass there would refractive errors which means that in the long run you have trouble seing far away and up close which is also called "hyperopia".

When illuminated with monochromatic light, a double slit produces a pattern that is a combination of single-slit diffraction and
d1i1m1o1n [39]

Answer:

The ratio is  k:d = 1 : 5

Explanation:

From the question we are told that

   The first minimum of the single slit pattern falls on the fifth maximum of the double slit pattern.

Generally the condition for constructive interference for as single slit is  

     ksin(\theta) = n\lambda

Here  k is the width of the slit  and n is the order of the fringe and for single slit n =  1 (cause we are considering the first maxima)

Generally the condition for constructive interference for as double slit is    

        dsin\theta = m\lambda

Here  d is the separation between the  slit  and m is the order of the fringe and for double slit  m  =  5  (cause we are considering the first maxima)

=>     dsin\theta = 5\lambda

So

       \frac{ksin(\theta)}{dsin(\theta)}  = \frac{\lambda}{5\lambda}

=>    \frac{k }{d}  = \frac{1}{5}

So  

      k:d = 1 : 5

A potential energy function for a system in which a two-dimensional force acts is of the form U = 3x6y − 5x. Find the force that
liq [111]

Answer:

Force, F=((-18x^5y+5)i+(-3x^6)j)\ N

Explanation:

Given that,

A potential energy function for a system in which a two-dimensional force acts is of the form of :

U=3x^6y-5x

We need to find the force that acts at the point (x, y). The force in 2 dimensional with components is given by :

F=(\dfrac{-dU}{dx},\dfrac{-dU}{dy})\\\\F=(\dfrac{-d(3x^6y-5x)}{dx},\dfrac{d(3x^6y-5x)}{dy})\\\\F=(-(18x^5y-5)),(-(3x^6))\\\\F=((-18x^5y+5)i+(-3x^6)j)\ N

So, the force acting at the point (x,y) is ((-18x^5y+5)i+(-3x^6)j)\ N. Hence, this is the required solution.

gtnhenbr [62]
<span>240,000 miles / hour² Average acceleration can be calculated by dividing the change in speed by the elapsed time. Since the dragster's speed was 0 when the light turned green, the change in speed is simply 300 mph. Now, divide that by the time: 300 mph / 0.00125 hours = 240,000 miles / hour² By the way, 0.00125 hours is just 4.5 seconds!</span>
