Explanation:
Two objects that only have the force of gravity acting on them, will fall with the same acceleration <span>g=9.8<span>m<span>s2</span></span>; g=32.2<span><span>ft</span><span>s2</span></span></span> and will therefore hit the ground at the same time.
When you drop a feather, air resistance acts on all the surfaces of the feather. This causes the feather to slow down.
Air resistance depends on two factors: the speed of the object (increased for example by throwing it), and its surface area.
hope this can give u a little bet more to know about how to get ur answer :P
have a gud day and gud luck!
The average kinetic energy of the atoms that make up a substance which is changing from a liquid to a solid is <span>decreasing. The answer is letter A. This is because there is more room for movement of atoms if the pahse is in liquid than in solid.</span>
Answer:
1.082 mm
Explanation:
From the question, we can see that we were given The following
Wavelength of the atoms, λ = 502 nm = 502*10^-9 m
Radius of the screen away from the double slit, r = 1.1 m
We know that Y(20) = 10.2 mm = 10.2*10^-3 m
d = (20 * R * λ) / Y(20)
d = (20 * 1.1 * 502*10^-9)/10.2*10^-3
d = 1.1*10^-5 / 10.2*10^-3
d = 1.082 mm
Therefore, we can say that the distance of separation between the two slits is 1.082 mm
High angular momentum leads to faster rotation, because faster rotation leads to collisions among particles that cause the gas to settle into a spiral disk, rather than a more spread out cloud.
What is the difference between an elliptical galaxy and a spiral galaxy?
Elliptical galaxies are ellipsoids with no clearly visible internal structure. Spiral galaxies have a very dense nucleus and a region of stars bulging outwards from the disks and, therefore, called the central bulge. Elliptical galaxies also have dense centers, but they do not protrude from the body of the galaxy.
Galaxies rotate, or spin around a central axis, and because of something called density waves, helps galaxies to become spiral in shape.

#SPJ4
Answer:
Here
Explanation:
They don't have free electrons moving around (delocalised electrons) so they can't conduct heat and electricity which gives them a property of good insulators. The insulators stop us having an electric shock because they don't conduct electricity as we use them to insulate metal wires and other metallic things. can i have brainliest now pls!
