Answer:

Calm water looks like a mirror from below because underwater light is entirely reflected when it comes from beyond a certain angle. This so-called total internal reflection also allows low power lasers to bend the waters surface.

thank you

Answer:

If you shine a light straight down at water, most of the light will go into the water, and some will reflect.

SO that would means:

- Laser would refract throught the water (in some part of it)

- But laser would also reflect from the water surface (in another part of it )

Another easy example:

- Sunshine go through water? (yes in the first few meters)

- Sunshine reflect with water? (yes, most of them would reflect )

Hope this helped :3

In a pool game, the cue ball, which has an initial speed of 3.0 m/s, make an elastic collision with the eight ball, which is ini

zhenek [66]

Explanation:

Given

initial speed(u)=3 m/s

mass of each ball is m

Let the cue ball is moving in x direction initially

In elastic collision Energy and momentum is conserved

Let u be the initial velocity and $v_1 , v_2$ be the final velocity of 8 ball and cue ball respectively

$\frac{mu^2}{2}+0=\frac{mv^2_1}{2}+\frac{mv^2_2}{2}$

The angle after which cue ball is deflected is given by

$\theta _1=90-40=50^{\circ}$

Conserving momentum in x direction

$mu=mv_1cos40+mv_2cos50$

$3=v_1cos40+v_2cos50$

Along Y axis

$0+0=v_1sin40-v_2sin50$

$v_1sin40=v_2sin50$

substitute the value of $v_1$

we get $v_2=1.912 m/s$

$v_1=2.27 m/s$

What is Kepler’s first law?

BartSMP [9]

Answer:

Kepler's First Law: each planet's orbit about the Sun is an ellipse. The Sun's center is always located at one focus of the orbital ellipse. The Sun is at one focus. The planet follows the ellipse in its orbit, meaning that the planet to Sun distance is constantly changing as the planet goes around its orbit.

zmey [24]

Answer:

v = 16.87 m/s

Explanation:

Given that,

Distance, d = 1.25 miles

d = 2011.68 m

Time, t = 1 minute 59.2 seconds

= 60 s + 59.2 s

= 119.2 s

We need to find the average speed of the horse. It is given by total distance covered divided by total time.

$v=\dfrac{2011.68 \ m}{119.2\ s}\\\\=16.87\ m/s$

So, his average speed is 16.87 m/s.

AVprozaik [17]

No. Sorry. A sound wave is a mechanical wave. There's nothing electromagnetic about it.
