The difference in hardness between diamond and graphite is that diamond has an ordered arrangement of atoms within its structure that makes it harder and stronger than graphite. This is due to the high pressure and high temperature that it went.

Neptune's Triton is being pulled closer and closer to the planet as it orbits. What will likely be a result of this gravitationa
Ksenya-84 [330]

Answer:

the planet's gravity will cause Triton to fly into Neptune

Explanation:

Gravitational force is a force of attraction between two bodies with considerable masses.

One of the mass tends to pull the other to it's center.

As the force of gravity between two bodies grow, the more massive body will be drawn to the other one.

  • The effect is that one body will eventually collide with the other.
  • Since the planet pulls very hard on its moon
  • On the long run, we can expect Triton to fly into Neptune in the foreseeable future.

What volume of stock solution and water must you add to prepare 36.25ml of a 1.25M solution
Serjik [45]

Given :

Number of moles , n = 36.25 mol .

Molarity , M = 1.25 M .

To Find :

The volume of water required .

Solution :

Moarity is given by :

M=\dfrac{n}{V}

So , V=\dfrac{n}{M}

Here , n is number of moles and M is molarity .

Putting all values in above equation , we get :

V=\dfrac{36.25}{1.25}\\\\V=29\ L

Therefore , volume of water required is 29 L .

You are using a ruler to measure the width of a test tube. The edge of the test tube is between 3 cm and 4 cm marks. if centimet
Arada [10]

Answer:

A) 3.6 cm

Explanation:

Accuracy comes down to how precisely you can read the length on a given scale. Here since the smallest increment is centimeter, we can go only one decimal beyond to estimate. This is because you can usually estimate to only one decimal place beyond the closest marks on any measuring.

So, the answer should be 3.6 cm.

Here's a document that explains it well: https://www.auburn.wednet.edu/cms/lib03/WA01001938/Centricity/Domain/1360/1_Uncertainty.pdf

Hope that's right!
