Answer:

6 - crimp

1 - strip cable end

8 - test

2 - untwist wire ends

4 - trim wires to size

7 - check

3 - arrange wires

5 - attach connector​

Explanation:

Step 1. Strip cable by inserting into the stripping tool. Rotate the cable in a smooth and even motion to create a clean cut and pull away towards the end of the wire to remove the sheathing.

Step 2. Untwist wire ends. Separate the twisted wires and straighten them out to easily sort in the right order.

Step 3. Arrange wires. Put the wires in the correct order so they can be properly crimped.

Step 4. Trim wires to size. Use the cutting section of the crimping tool to cut them into an even line.

Step 5. Attach connector. Insert the connector so that each of the small wires fits into the small grooves in the connector.

Step 6. Crimp. Insert the connector in the crimping tool. Squeeze the handles to crimp the connector and secure the wires.

Step 7. Check. Take the connector our of the tool and look at the pins to see that they're all pushed down.

Step 8. Test. Lightly tug at the connector to make sure it's attached to the cable.

Describe how you would use the principle of “staging” in a scene in an animated film that shows a triumphant moment in a soccer game played in a large stadium.

Describe a situation where an animator might choose to intentionally violate the principle of “slow in and slow out.”

Imagine that you had been given the task of animating a crab walking along the seashore. How would you use the animation principle of secondary action to make the scene appear more realistic?

Answers

Answer: The only thing i could find was this I hope this helps you out

Timing and Spacing: The number of frames between two poses, and how those individual frames are placed.

Squash and Stretch: The flexibility of objects to exaggerate or add appeal to a movement.

Anticipation: The setup for an action to happen.

Ease In and Ease Out: The time for acceleration and deceleration of movement.

Follow Through and Overlapping Action: The idea that separate parts of the body will continue moving after a character or object comes to a full stop, and the idea that parts of the body will move at different times.

Arcs: The principle that smooths animation and moves action in a realistic way.

Exaggeration: The pushing of movement further to add more appeal to an action.

Solid Drawing: The accuracy of volume, weight, balance, and anatomy.

Appeal: The relatability (or charisma) of a character.

Straight Ahead Action and Pose to Pose: The spontaneous and linear approach to creating an action using many in-between poses along with the main poses, and the more methodical approach to creating an action using only a few poses.

Secondary Action: The actions that emphasize or support the main action of the animation.

Staging: The setting up of the scene, from placement of characters to the background and foreground elements, to how the camera angle is set up, the lighting and shadows, and more.

Explanation:

Answer:

1. Linear motion is motion in a straight line. Non-linear motion is motion that is not in a straight line. For example when you move your pen in a line it is linear.

2. They might use something to show the mountain and show how big it is. Using effects like this can bring out certain parts and bring out what really is trying to be shown in a movie.

3. The camera angle of the soccer game and the follow with the ball being shown can give a staging looking for what is coming or what is important in that time.

4. You can use it to show how fast a car is going or to show where a person is at on a map in a 3rd person view

5. I would use Arcs because it smooths out the image or video to make whatever your trying to make look more realistic.

What are the chances of a baby zombie to spawn in full golden armor in MC? ​

Answers

Answer:

Baby Zombies can spawn naturally in the Overworld, but they only have a 5% chance to spawn. The player can also spawn one with a Zombie Spawn Egg. Baby Zombies can also be found riding a Chicken, creating a Chicken Jockey.

Explanation:

It is very unlikely for a baby zombie to appear wearing shiny golden armor.

Why is this so?

It is not common for a zombie to appear with armor, and it is even rarer for a baby zombie to wear a full set of golden armor.

The chance of this event happening is different for each version and if any changes have been made to the game. However, in the regular MC with no changes, the chances are usually low.

Answers

The programing language, R has a unite unite function in the tidyr package. Hence, the code chunk which let's the analyst create the location column is; unite (stores, "location”, city, state, sep=",")

The syntax for the unite function is ; unite(data,col,..., sep)

data = dataframe from which data is to be extracted `; stores col = name of the new column ;" location"... = dataframes to be merged ; city, statesep = seperator ; ","

calculate the speed when given the amount of 1TB to be transfer in 5hrs.

Answers

Answer:

Data transfer rate is the speed that a certain amount of data is transferred over a given period of time. You might want to know the transfer rate if you’re downloading something online or transferring data from one source to another. First, convert your units so the file size and transfer speed are in either bits or bytes with the same prefix (kilo, mega, giga, or tera). Then, plug your numbers into the equation S = A ÷ T in which A is the amount of data and T is the transfer time to solve for S, the speed, or rate, of transfer. You can also determine the amount of data or the transfer time if you know one of the variables plus the speed of transfer.
