Light rays reflected from the fish are refracted at the surface of the water, but the eyes and brain trace the light rays back into the water as thought they had not refracted, but traveled away from the fish in a straight line. This effect creates a "virtual" image of the fish that appears at a shallower depth.

Answer:

Because of refraction.

Explanation:

Light coming from fish passes through two medium, one is water and another is air. As the density of medium is changing from high to low, the light bends away from the normal. So to the human eyes, the fish appears to be above its actual position.

. What is the difference between a combinational circuit and sequential circuit? Give example of each.

Licemer1 [7]

A combinational circuit is a complex circuit with different elements... for eg. computer motherboard is a very complex circuit with a lot of different elements connecting other components of computer as well.

A sequential circuit is a bit more primitive often a part of combinational one. For eg. three resistors connected in parallel.

Hope this helps.

natulia [17]

Answer: Geotagging was enabled on her smartphone

Explanation:

The security weakness that is the most likely cause of the security breach is that geotagging was enabled on the vice president's smartphone.

Geotagging, occurs when geographical identification metadata are added to websites, photograph, video, etc. Geotagging can be used to get the location of particular place.

In this case, since geotagging was enabled on her smartphone, it was easy for the attacker to locate her house.

import json #import package

#define function

def read_json(info):

return json.loads(info)#load data in variable

#call and print the function

print(read_json('[{'A': 10}, {'Y': 16}, {'U': 28}]'))

<u>Output</u>:

[{'A': 10}, {'Y': 16}, {'U': 28}]

Explanation:

following are the description of the code

Define function "read_json()" and pass an argument "info" inside it.
Return the data inside from the "load()" function .
