Answer:
All of these choices are correct. US Government posters during World War II often displayed slanted language, ethnic biases and nationalistic biases.
Explanation:
The posters placed by the federal government on public roads, transportation and other places of high circulation of people during World War II had as their main and fundamental objective the creation of a united and strong domestic front, where all citizens collaborated with the effort of the thousands and thousands of Americans on the battlefront through the production of food, medicine, supplies, and weapons, and the rationing of their own consumption in order to allocate most of the resources to these soldiers. In addition, these posters attempted to encourage many young Americans to join the ranks of the military, by spreading nationalist (such as Uncle Sam and his "I Want You" message) and ethnicists slogans (such as posters depicting Japanese and Germans as sadistic and evil beings).
All this propaganda was effective in its initial purposes, since it generated a feeling of union and collaboration that allowed a greater allocation of resources for the armed forces that were fighting in Europe and the Pacific.

The additional measurements which must be made to determine the momentum of block 2 after the collision is both the mass and the post-collision speed of block 1
<h3>What is momentum?</h3>
Momentum can be defined as a scalar quantity that involves the multiplication of the mass of an object by its velocity.
In Physics, the momentum of an object such as a block, is calculated by using this formula;
Momentum = mass × velocity
In conclusion, we can deduce that the additional measurements which must be made to determine the momentum of block 2 after the collision is both the mass and the post-collision speed of block 1.

- Nitrogen,
- Calcium,
- Hydrogen
Essential trace elements:
The complete question
The elements are: Hydrogen, iron, Copper, Nitrogen, Helium, Carbon, Aluminum, Calcium, Argon
<h3>What is Essential and Nonessential Elements?</h3>
Nonessential elements as the name implies are elements which are not necessary for the functional routine of the body and hence are not included in diets.
Essential bulk elements are elements which are needed for the proper functioning of the body and hence are required in relatively large amounts.
Essential trace elements are required in minute quantities in the body.
