Answer:
I believe it's B. A meeting spot for family members
Explanation:
Make copies of your Family Emergency Communication Plan for each member of the household to carry in his or her wallet, backpack, or purse. So they know where to go in case of an emergency!
Answer:
<h2 /><h2>1) Radon is colorless at standard temperature and pressure and it is the most dense gas known. At temperature below it's freezing point is has a brilliant yellow phosphorescence. It is chemically unreactive, it is highly radioactive and has a short half life.</h2>
<h2>2) 7.5 times heavier than air and more than 100 times heavier than hydrogen. The gas liquefies at −61.8 °C (−79.2 °F) and freezes at −71 °C (−96 °F). On further cooling, solid radon glows with a soft yellow light that becomes orange-red at the temperature of liquid air (−195 °C [−319 °F]).</h2>

As we know that gravitational force of Sun will provide the centripetal force to all planets
so here we will have
here we know that
now from above equation
Position <em>' C '</em> is the middle of the swing. That's where the weight is the lowest.
It's also the place where the weight is moving the fastest, so that means it's the place where the kinetic energy is greatest.
If a coin is dropped at a relatively low altitude, it's acceleration remains constant. However, if the coin is dropped at a very high altitude, air resistance will have a significant effect. The initial acceleration of the coin will be the greatest. As it falls down, air resistance will counteract the weight of the coin. So, the acceleration will decrease. Although the acceleration decreases, the coin still accelerates, that is why it falls faster. When the air resistance fully counters the weight of the coin, the acceleration will become zero and the coin will fall at a constant speed (terminal velocity). So, the answer should be, The acceleration decreases until it reaches 0. The closest answer is.
a. The acceleration decreases.
