Answer:
Explanation:
The concept of a new strong nuclear force was introduced. In 1935, the first theory for this new force was developed by the Japanese physicist Hideki Yukawa, who suggested that the nucleons would exchange particles between each other and this mechanism would create the force.
The calorie was originally defined as the amount of heat required at a pressure of 1 standard atmosphere to raise the temperature of 1 gram of water 1° Celsius. ... Since 1925 this calorie has been defined in terms of the joule, the definition since 1948 being that one calorie is equal to approximately 4.2 joules.
A Many people who came to the hospital had very serious injuries.
Explanation:
From the passage, we can infer that many people who came to the hospital had very serious injuries.
Let us analyze the given options:
Many doctors were worried about the safety of their own families.
No where in the passage was the families of the Doctors mentioned. The passage directly spoke to the Doctors and their victims.
Many people were able to quickly leave the hospital after treatment.
There was shortage of blood and there was no way they could have been treated without it. The passage suggests an emergency situation was up.
Also, many people needed blood for treatment but there was an acute shortage. No way to treat and discharge them.
Many doctors who worked through the night wanted to go home.
Again, no text in the passage suggests this. We have a picture of Doctors who wanted to tend to their patients but lacked the means to do so.
<em>The fitting inference that can be drawn from the passage is that many people came to the hospital had serious injuries which led to blood shortage. </em>

The answers penciled in on the sheet are fine ... 1500 Hz and 0.0006 sec.
If you want to get super-technical about it, you could count the number of full cycles on the WHOLE graph, from one side to the other. At the right end, near 0.01 sec, you can notice an extra 1/4 of a cycle there. So it's actually 15 and 1/4 cycles in 0.01 sec.
That makes the frequency (15.25 cycles) / (0.01 sec) = 1,525 Hz .
and the period ( second / 1525) = 0.000656... second.
But I think it would be OK if you didn't do that, and just call it 1500 Hz and 0.0006s.
The difference is only 1.6% , and the engineer in me says that's not enough to worry about.
I believe it's potassium.
