What is a Vector and a scalar?

Answers

Scalars are quantities that are fully described by a magnitude (or numerical value) alone.
Vectors are quantities that are fully described by both a magnitude and a direction.

Arrange the substances in the table from the MOST to the LEAST ordered particle arrangement
A)
wood, water, neon gas
B)
wood, neon gas, water
water, wood, neon gas
D
water, neon gas, wood

Answers

Answer:

I think the correct answer from the choices listed above is option A. The correct arrangement of the substances according to the most to the least ordered particle arrangement should be wood, water and neon gas. Wood should be the first since it is solid which has the most ordered structure as compared to the liquid and a gas. The neon gas is the last since as a gas it has the least ordered structure.

Answer:

A) wood, water, neon gas

Explanation:

wood, water, neon gas.

The particles of solids have an arrangement that is highly ordered and regular. Liquids have an arrangement that is less ordered, and the particle arrangement in gases is the least ordered and regular of the three states of matter.

tell me if im wrong .... hope this helps :)

Which nucleus would be least likely to undergo radioactive decay?

Answers

A large nucleus. This is because the nuclear forces are not as strong as the repulsive electrical forces between nucleons. The said nuclear force is more or less the surface tension force. In a large nucleus, it is not as strong as the repulsing forces in a smaller nucleus.

Answer:

Stable nuclei will not undergo in nuclear decay reactions. Stability of nucleus depends upon the force between nucleons.

If there is strong attraction force between the nucleons then the repulsion force between the protons will be neglected over this strong force and the nuclei is stable.

Also we can check the stability of nucleus by the ratio of neutrons and protons in the nucleus.

here the stability of nucleus is more it the ratio lie between 1 and 1.2 i.e.

1 < (N)/(P) <1.2

so the neutron to proton ratio will decide the stability of nucleus.

So it the ratio lie for above range of neutrons and protons then it is least likely to go radioactive decay.

What are two ways in which all types of precipitation are alike

Answers

The two ways in which all types of precipitation are alike they all come from the clouds,they are all formed by precipitation.

What is precipitation ?

Any liquid or frozen water that condenses in the atmosphere and falls to the ground is known as precipitation. Rain, sleet, and snow are only a few of its various manifestations. Precipitation is one of the three main processes that make up the global water cycle, together with evaporation and condensation.

Rain, sleet, and snow are only a few of its various manifestations. Precipitation is one of the three main processes that make up the global water cycle, together with evaporation and condensation. Water vapour in the clouds condenses into increasing-sized droplets of water, forming precipitation.

The most common forms of precipitation that come from cloud-borne particles are rain, snow, freezing rain, and sleet. The changes in temperature are the primary distinction between these various types of precipitation.

Thus, The two ways in which all types of precipitation are alike they all come from the clouds,they are all formed by precipitation.

The formula for degrees Celsius is: C = 5/9 (F − 32), where F stands for degrees Fahrenheit.Part 1: Solve the equation for F and show all steps.
Part 2: Determine how many degrees Fahrenheit 20 degrees Celsius is.

Answers

C = 5/9 (F-32)Part 1.  C=5F/9-(5/9)325F/9=C+160/9F=(9/5)C+(9/5)(160/9)F=(9/5)C+32for part 2:
