Hello!
I believe C) immunizations are a high-priority health in the United States. First let's talk about what immunizations are. Immunizations are a liquid that is injected into your body by needle. This liquid then enters your blood stream and it gets pumped into all of your body because of your circulatory system. So it spreads all around your body and when you get sick, that vaccine helps to get rid of the disease way quicker or even not at all. The U.S government are in high demand to prevent serious disease by giving people the vaccines because many people are getting sick from, for instance, cancer. Although the actually vaccine cannot cure cancer it can prevent it from happening.
I hope it helps!

Answer:
The sound travelled 516 meters before bouncing off a cliff.
Explanation:
The sound is an example of mechanical wave, which means that it needs a medium to propagate itself at constant speed. The time needed to hear the echo is equal to twice the height of the canyon divided by the velocity of sound. In addition, the speed of sound through the air at a temperature of 20 ºC is approximately 344 meters per second. Then, the height of the canyon can be derived from the following kinematic formula:
(1)
Where:
- Height, measured in meters.
- Velocity of sound, measured in meters per second.
- Time, measured in seconds.
If we know that 
and 
, then the height of the canyon is:
The sound travelled 516 meters before bouncing off a cliff.
Answer:
The rate of acceleration is 7.441 m/s/s.
(19 - 2.6) * 9.8 / (19 + 2.6) = 7.441
The tension in the cord is 44.826 Newtons.
2.6 * (9.8 + 7.441) = 44.826
or
19 * (9.8 - 7.441) = 44.826
