Decreased it because you can float a lot
"Free fall" means that gravity is the ONLY force acting on the object. If there's air resistance, then it isn't free-fall.
Objects that fall near earths surface are ALWAYS falling through air, unless they're inside some kind of a vacuum chamber with all the air removed from it.
Answer:
No
Explanation:
You can easily injury yourself due to the force of gravity.
Answer:
The separation distance between the slits is 16710.32 nm.
Explanation:
Given that,
Wavelength = 641 nm
Angle =4.4°
(a). We need to calculate the separation distance between the slits
Using formula of young's double slit


Where, d = the separation distance between the slits
m = number of order
=wavelength
Put the value into the formula



Hence, The separation distance between the slits is 16710.32 nm.
Radio waves are a type of electromagnetic wave that can travel when there is no medium, whereas sound waves are a type of mechanical wave that cannot travel if there is no medium
