The volume of a balloon is like that of a sphere. So we use 4/3x Pix radius3 .
Now plug in some numbers for V and see how radius changes. You will see if you go from a small volume to one a little larger, say .1 to .15, there is a pretty big change in the radius. Now try 1000 to 1000.15. You will see the change in the radius is much smaller.
That is because of the fact the radius is cubed. I can't draw it here, but have a look at the graph of x cubed and that may shed some light on it.
Area of a circle = (pi) x (radius)2 (pi) = about 3.1416 or about 22/7 . (It can never be written down exactly.) (radius)2 = (radius) x (radius)
If you cut the cone in half then drop a line from the point down to the centre of the base, you can then find the radius, which is the the base of one of the triangles you now have. You need to know one of the angles though, then work out the radius through trigonometry.
Depends. IF you mean BALLOON then the following is the answer If it is a small cold air balloon gravity simply pulls it down as it is denser than the surrounding air (ie. it weighs more for the space it take up then the surrounding air it displaces). If it is a hot air balloon then the hot air has expanded so as to displace the heavier cold air inside and around the balloon and now being less dense than the surrounding air it simply floats upwards defeating gravity (the reality is that the balloon only appears to rise - what actually happens is that the colder air falls around the hot air). Once the hot air cools the balloon shrinks in size displacing less cold air around it and it is now denser than the surrounding air and gravity takes over and the balloon is pulled toward the earth (commonly called "down") IF you really meant a guy named Ballon he was a German ballet dancer and probably tripped IF you mean a Balloon flask as used in Chemical procedures to catch the drippings of distillation then some one only has to knock it off the bench. IF you mean the village of Ballon it is already ground. Although the air in the balloon is the same density as the air outside, the rubber weighs it down pulling it to the ground. This doesn't happen with helium balloons because they are so much less dense than air that they can carry the plastic.
K
as i calculate it its 346, its the only cube number that's bigger than 200 but smaller than 400
With same mass, balloon get bigger with air than water because air is much lighter than water. With same standard volume, balloon get bigger with water than air because air is compressible and it will shrink down little bit from the pressure exerted by balloon wall.
The particles in the balloon slow down as the temperature decreases cause it to deflate
i believe that it is the ulna. the ulna starts as your elbow and runs down to your wrist. it is both thicker and longer than the radius.
It tends to increaseThe atomic radius increases down the group
The larger the highest energy level, the larger the atomic radius.
Filling up a balloon with hot air is a physical change. The hot air causes the particles within the balloon to expand and increase in kinetic energy, leading to an increase in pressure inside the balloon. Once the balloon cools down, the particles contract, causing the balloon to deflate, but no new substances are formed.
Forces have an indirect impact on the atomic radius of alkali metals. As you move down a group of alkali metals in the periodic table, the atomic radius typically increases due to increased electron shells. The forces between the electrons and nucleus (electrostatic forces) contribute to the overall size of the atom in terms of atomic radius.
the larger the highest energy level number, the larger the atomic radius (Apex)
As the warmer air inside the balloon cools, the balloon will shrink slightly. The amount of shrinkage will depend on the temperature change.
After a cool change, the air inside the balloon cools down, causing it to contract and deflate slightly. This is because the molecules inside the balloon have less energy and move closer together. Once the balloon warms up again, the air inside will expand and the balloon will return to its original size.
Mg has a larger atomic radius than Na. This is because atomic radius generally increases as you move down a group in the periodic table, and Mg is below Na in the same group. Additionally, Mg has more energy levels and electrons compared to Na, contributing to its larger atomic radius.
As you move down a group in the periodic table, the ionic radius tends to increase due to the addition of new electron shells. Across a period from left to right, the ionic radius generally decreases as the increasing nuclear charge pulls the electrons closer to the nucleus, resulting in a smaller radius.
