Answer:
5.2x10^-25
Explanation:
Time=(1.56x 10^-16)÷(3x10^8)
I just got this question not to long ago but to answer your question the primary function of the respiratory system is to exchange oxygen<span> and carbon dioxide. Inhaled </span>oxygen enters the lungs<span> and reaches the alveoli. </span>Oxygen<span> passes quickly through this air-blood barrier into the blood in the capillaries. Similarly, carbon dioxide passes from the blood into the alveoli and is then exhaled.</span>
If you include the effects of falling through air, then you have to know the
shape, size, weight, and surface texture of the objects. You also have to
know the height from which they're dropped, and the temperature, pressure,
and humidity of the air. All these things make a difference in how they fall.
If you ignore the effects of falling through air, like build a giant metal tank
and pump all the air out of it, and ONLY talk about the effects of gravity, then
ALL OBJECTS accelerate at the same rate. If you drop two things from the
same height at the same time, then they both hit the ground at the same time,
traveling at the same speed, no matter what they are. They could be a piece of
tissue and a car !
There are several museums where they have a big glass pipe that you can
see through, and they pump the air out of the pipe and drop a feather and a
bowling ball from the top inside at the same time, and they both reach the
bottom together.
If gravity is the only force on an object, then all objects fall at the same rate.
Assuming that there is in a vacuum, the two object will cool at the same rate, because the objects are made of the same material they will have the same cooling rate, assuming the surrounding temperature is the same.
