Answer:
Option (C)
Explanation:
Einsteinium is an element of the periodic table grouped in the Actinide series, with atomic number 99. They are dense element and highly electro-positive. <u>They are highly radioactive</u>, i.e the atoms within the element are unstable and constantly decay until they reach a stable environment. It has 99 number of electrons and protons, 153 number of neutrons.
Due to its high radioactivity, they are health hazardous and can used in making nuclear weapons but their uses are very limited and unknown.
Thus, the correct answer is option (C).
<h3><u>Answer;</u></h3>
The above statement is False
<h3><u>Explanation;</u></h3>
- Decreased output from the vasomotor center allows arterioles and veins to dilate.
- The vasomotor center controls vessel tone or contraction of the smooth muscle in the tunica media.It is responsible for central regulation of cardiac electrical activity, myocardial performance, and peripheral vascular tone.
- Changes in diameter affect peripheral resistance, pressure, and flow, which in turn affect cardiac output.
W=f*d = 5000N * 10 stories * each 4m = 200 000 J
