You are in a desert on a hot day and see water in the distance. It is not really there, you see it because light bends due to a difference in the temperature of air. Which behavior of light best explains this? Select one: a. reflection b. translocation c. diffraction d. refraction

Answers

Answer 1

Answer:

Answer:

d) refraction

Explanation:

in physics, refraction is the change of direction of a wave passing from one medium to another. refraction of light is the most commonly observed phenomenon but other waves such as sound waves and water waves also experience refraction

Answer 2

Answer:

Answer:

B. Translocation

Explanation:

It means a change in location. It often refers to genetics, when part of a chromosome is transferred to another chromosome, you want a change in location because you are so thirsty in the desert and need water

The period of a ball moving in a circle is doubled while the radius stays the same. What happens to the velocity of the ball?

Answers

Answer:

The velocity of the ball becomes half when the time period is doubled.

Explanation:

Let $T$ be the time period of the ball, $R$ be radius and $v$ be the velocity of the ball performing circular motion.

Now, for a circular motion, the velocity is given as:

$v=(2\pi R)/(T)$

From the above relation, we can conclude that, velocity is inversely proportional to time period if the radius is constant.

This means that if time period is increased, velocity will decrease and vice-versa.

So, if time period is doubled, the velocity will reduce by half. This can be verified mathematically also given below.

$v_o=(2\pi R)/(T)\nv_n=(2\pi R)/(2T)$

Divide $v_n$ by $v_o$ , we get

$(v_n)/(v_o)=((2\pi R)/(2T) )/((2\pi R)/(T) )\n(v_n)/(v_o)=(T)/(2T)\n (v_n)/(v_o)=(1)/(2)\n\therefore v_n=(1)/(2)v_o$

Here, $v_n\ and\ v_o$ are the new and old velocities.

So, it can be concluded that if the time period is doubled, velocity is reduced by half.

SQUA is a square. If side SQ has endpoints S(-2,8) and Q(4,10), find the perimeter to two decimal places?HURRY!!

Answers

Answer : The perimeter of square is, 25.28 unit.

Step-by-step explanation :

First we have to calculate the distance of SQ.

Using distance formula:

$d=√((x_2-x_1)^2+(y_2-y_1)^2)$

where,

d = distance between the two coordinates

x and y are the coordinates.

To calculate the distance of SQ:

$d=√((x_2-x_1)^2+(y_2-y_1)^2)$

$d=√((4-(-2))^2+(10-8)^2)$

$d=√((36)^2+(4)^2)$

$d=√(40)$

$d=6.32$

As we know that SQUA is a square that means all sides are equal.

So, Side SQ = Side QU = Side UA = Side SA = 6.32

Now we have to calculate the perimeter of the square.

Perimeter of square = Side SQ + Side QU + Side UA + Side SA

Perimeter of square = 6.32 + 6.32 + 6.32 + 6.32

Perimeter of square = 25.28 unit.

Therefore, the perimeter of square is, 25.28 unit.

Final answer:

To find the perimeter of the square, calculate the length of one side using the distance formula and multiply it by 4.

Explanation:

To find the perimeter of a square, we need to know the length of one side and multiply it by the number of sides. In this case, the length of one side can be found using the distance formula, which is the square root of the sum of the squared differences in the x-coordinates and y-coordinates of the endpoints of the side. So, the length of side SQ is:

Length of SQ = √((-2 - 4)2 + (8 - 10)2) = √((-6)2 + (-2)2) = √(36 + 4) = √40 ≈ 6.32

The perimeter of the square is found by multiplying the length of one side by 4, since a square has 4 equal sides:

Perimeter = 4 * Length of SQ = 4 * 6.32 = 25.28

Therefore, the perimeter of the square to two decimal places is 25.28 units.

the image of a mountain can be seen on the surface of calm water. what property of light is demonstrated?

Answers

Answer:

It is Reflection of light from water surface

Explanation:

When light coming from the mountains incident on the stationary water surface then major proportion of light gets reflected from the surface of water and this will received by the observer eye.

We also know that when light beam gets reflected into the form of beam then it is known as regular reflection.

Here when water surface is calm then the surface is assumed to be plane and in this case the light gets reflected by the surface of water in same direction and we got a good image in the water.

So this property of image is due to reflection of light.

I say it's the regular reflection
