Answer:

The correct answer is option C.  electromagnetism.

Explanation:

All text messages, photos and videos that we send through our wireless devices manage to transfer this data through a force called electromagnetism.

<u>This force is one of the 4 natural forces that exist in nature</u> and in it the electric fields interact with the magnetic fields.

Around us there is an invisible field called <u>electromagnetic field</u>, and this field can sometimes be disturbed by electromagnetic waves. These types of disturbances are what allow an <u>electromagnetic wave to travel and send information. </u>

The information will travel as a wave and will be received by an antenna, which will decode those waves in order to obtain the information that is being transported.

What is the binary representation of the following hexadecimal numbers?
Dahasolnce [82]

Answer:

Corresponding Binary numbers are as following:

A4693FBC=10100100011010010011111110111100.

B697C7A1 = 10110110100101111100011110100001.

Explanation:

A single digit hexadecimal number is a 4 bit binary number.So for each hexadecimal bit we have to find the corresponding 4 bit binary number.

A=1010

4=0100

6=0110

9=1001

3=0011

F=1111

B=1011

C=1100

and write them in the same sequence of their hexadecimal number.

A4693FBC=10100100011010010011111110111100.

B=1011

6=0110

9=1001

7=0111

C=1100

7=0111

A=1010

1=0001

B697C7A1 = 10110110100101111100011110100001.

The light you shoot in will dictate what shutter speeds to use.
Nesterboy [21]

Answer:

The three things that will determine your exposure are film speed, aperture and shutter speed. The speed of the film dictates how much light the film needs. The aperture controls how much light comes through the lens. And the shutter speed then controls how much of that light hits the film. These three things always work together to produce your image.

The shutter speed, sometimes known as exposure time, determines the amount of time your film is exposed to light when taking a photograph. So, you always need to balance your aperture and shutter speed to get a correct exposure.

The general rule is you need to shoot with at least 1/60 to get sharp images when shooting handheld. It is best to use a tripod if you want to shoot with a slower exposure time as this will help reduce any camera shake.

Fast Shutter

Fast speeds are really good for freezing fast-moving subjects. You need to make sure you are using a fast exposure time if you are trying to take a sharp image of a fast subject. Different cameras have different options but commonly you can choose something like 1/500.

Higher ISO film will also allow you to utilise the faster shutter speeds as they are more sensitive to light.

Slow Shutter

Slow shutter speeds will visibly record motion. They are often used to create the effect of motion in an image. A moving subject captured with a slow exposure time will be captured as a blur across the image. Slow exposure times are also necessary when taking photos at night. They allow you to get enough light to expose your image correctly.

Be careful when using slow exposures without a tripod. The slower the shutter the more likely that you will have visible camera shake in the image.

Reading Shutter Speeds

Shutter speed is measured in fractions of a second. So, for example, 1/60 is read as one-sixtieth of a second. The bigger the second number in the faster the speed.

Typical shutter speeds you will see are; 1, 1/2, 1/4, 1/8, 1/15, 1/30, 1/60, 1/125, 1/250 and 1/500.

In a relational database, a primary key is sometimes made up of multiple fields. What is this known as?
wlad13 [49]

Answer:

Foreign key is the correct answer for the above question.

Explanation:

  • A foreign key is a key that is used to extract the information of a foreign table with the help of primary key value. When there is a normalized table then it needs to split on two or more tables to overcome the problem of normalization.
  • So is there is a two table then the primary key is used for the first table and the combination of the primary key and foreign key is used to identify the record of the foreign table. The foreign key is made up of multiple fields because there is no single field in the foreign which can not be null for any instance of the primary table. It happens when there is data for the primary table but there is no record for the foreign table.
  • The above question wants to ask about the term which is made up of multiple fields which is a foreign key which is described as above. Hence Foreign key is the correct answer for the above question.
