Answer:
Hey you can talk to me I don't know how we would talk but I can keep a secret. I know the feeling of not having anyone to talk to.
One kilogram is equal to one thousand grams. Further, one gram is equal to 1000 mg. The conversion is as shown below,
(6.285 x 10³ mg) x (1 g / 1000 mg) x (1 kg / 1000 g)
The numerical value of the operation above is 0.006285 kg.
Answer:
Displacement. (I think)
Explanation:
When you observe both a bowling ball and a feather falling to the ground at the same time, you see that the feather falls much slower. This is because the feather displaces the air around it.
Look closer at the feather. Notice that all the feather is are fibers sprouting from the quill. The air moves through these fibers slower and displaces the air around them. this is what helps birds to fly and glide.
Now observe someone in a flight suit. A flight suit has a type of fabric webbing in-between the arms and legs of the wearer. This allows them to glide through the air (when they gain lift) because the higher surface area of a light material displaces the air around it.

Answer:
In the chemical bonds.
Explanation:
There are different types of chemical bonds, some store a TON of energy while others do not store as much. You can think of it like this: for bonds with low energy, it takes a LOT of force to pull them apart, meaning they are strong bonds. However, this way, you have to put energy into them to break the bonds and form a chemical reaction. This is an endothermic reaction, a reaction that absorbs heat from its surroundings.
Instead, bonds in exothermic reactions are BEGGING to form a more stable bond, and hence store a lot of potential energy. Due to the difficulty of maintaining these bonds, there is a lot of energy put into them. If you break them, however, (exothermic reaction) the energy is released, and hence the exothermic reaction happens.
Hope this helped. Please give Brainliest! :>
