Answer 1

Answer #1

Our milky way galactic disk has a diameter of 100,000 light-year

Average male person height is 1.75 metre.

1 light year= 9.461x10¹⁵ metre

so 100,000 light-year = 9.461x10²⁰ metre

so by calculating we can conclude that the diameter of our galactic disk is 5.4x10²⁰ times bigger than the average man's height.

A typical raindrop is much more massive than a mosquito and falls much faster than a mosquito flies. How does a mosquito survive the impact? Recent research has found that the collision of a failing raindrop with a mosquito is a perfectly inelastic collision. That is, the mosquito is "swept up" by the raindrop and ends up traveling along with the raindrop. Once the relative speed between the mosquito and the raindrop is zero, the mosquito is able to detach...

Why does Ca have a bigger atomic radius than Na? The periodic trend for atomic radius says that the lower and more to the left an element is, the greater it's atomic radius. In our case, Na is more to the left, but the Ca is lower down. How do we reconcile this?
