Neon has 10 protons and 10 electrons. How many additional electrons would it take to fill the outer (second) electron shell?

Answers

none because Neon is already stable

The reason why the position of an electron cannot be measured with absolute precision is:

Answers

They are too small are never in the same place. Electrons are constantly moving in random motion within the electron cloud, making them impossible to follow.

Material speed of lightspace 3 x 108 m/s
water 2.25 x 108 m/s
glass 2 x 108 m/s
air 3 x 108 m/s

Light moves from air into a new material. The greatest refraction would occur when light passes through which material?
A) air
B) glass
C) water
D) It would refract the same amount in each material.

Answers

The question is poor. Light doesn't refract on its way THROUGH anything. It refracts at the boundary BETWEEN two different media. The effect is greatest where the ratio of the speeds of light in the two media is greatest. On your list, that would be at the boundary between air or space and glass.

Answer: I think the answer is B glass.

Explanation: Because Glass is light.

A 360-N child is in a swing that is attached to a pair of ropes 1.90 m long. Find the gravitational potential energy of the child–Earth system relative to the child's lowest position at the following times.

Answers

Answer:

684J

Explanation:

So basically the formula for gravitational potential energy is Mass X Gravity X height. That is G.p.e = mgh

We don't have the mass but since we have the height, we multiply directly with the height since the quantity of weight is already given.

so G.p.e = 360 X 1.9 = 684J

Note that; The answer is in joules because g.p.e is work done.

Hope that was helpful!!

The least common shape for a galaxy is cluster.Galaxy, by definition, is an arrangement composing of stars, planets, gassesand everything more that can be seen in the space. There are three types ofgalaxies and they are elliptical, spiral and irregular. Spherical could beapplicable as elliptical if you got to choose only one on the choices above. Exampleof spiral galaxy is the Milky Way galaxy where our Solar system is currentlylocated according to the scientists.

Answer:

cluster

Explanation:

An object weighs 60.0 kg on the surface of the earth. How much does it weigh 4R from the surface? (5R from the center)

Answers

"60 kg" is not a weight. It's a mass, and it's always the same
no matter where the object goes.

The weight of the object is

   (mass) x (gravity in the place where the object is) .

On the surface of the Earth,

   Weight = (60 kg) x (9.8 m/s²)

      =    588 Newtons.

Now, the force of gravity varies as the inverse of the square of the distance from the center of the Earth.
On the surface, the distance from the center of the Earth is 1R.
So if you move out to 5R from the center, the gravity out there is

(1R/5R)² = (1/5)² = 1/25 = 0.04 of its value on the surface.

The object's weight would also be 0.04 of its weight on the surface.

   (0.04) x (588 Newtons) = 23.52 Newtons.

Again, the object's mass is still 60 kg out there.
___________________________________________

If you have a textbook, or handout material, or a lesson DVD,
or a teacher, or an on-line unit, that says the object "weighs"
60 kilograms, then you should be raising a holy stink.
You are being planted with sloppy, inaccurate, misleading
information, and it's going to be YOUR problem to UN-learn it later.
They owe you better material.

Answer:

23.5 N

Explanation:

Just wanted to clarify something about the verified answer: Our only given measurement—the mass of the object—has 3 significant digits, so we can only include 3 significant digits in our answer.

23.52 N is NOT the correct answer. Your answer should only have 3 significant digits.

I just did the quiz where this problem came from, so I know that 23.5 N is the correct answer.
