The outer planets (Jupiter, Saturn, Uranus, Neptune) are called the "<u>GAS</u> giants".

The rocky planets are called "rocky" because they're made of <u>ROCK</u>.

Does this help guide you to the correct choice ?

Here's another hint: The MOST dense planet in our solar system, the one we call "Earth", is one of the 'rocky planets'.

The quantum state of a particle can be specified by giving a complete set of quantum numbers (n,l, ml, ms). How many different q

Delvig [45]

Answer:

number of quantum states = 8

Explanation:

To find the total number of allowed states you take into account the following relations:

$l=n-1\\\\m_l=-l,-(l-1),...,0,,,,(l-1),l$

in this case you have:

$n=2\\\\l=0,1\\\\m_0=0\\\\m_1=-1,0,1$

furthermore, for each n,l,ml quantum state you have two additional states due to the spin of the electrons.

then, you have (n,l,ml) = (2,0,0), (2,1,-1), (2,1,0), (2,1,1) and with the spin:

number of quantum states = 2*(1+3) = 8

What distance was an object moved by a force of 40 N if the work was 600 joules

Westkost [7]

If a force of 40 N does 600 joules of work, then it must have been applied continuously through a distance of (600/40) = 15 meters .

We can't tell how far the object ultimately moved, because we don't know
what other forces may have been acting on it. If there were NO other forces,
then it just kept going, even after the 40-N force stopped, with the same
600 joules of kinetic energy that it got from the work that the force did.

When you use paper money to pay for food, the money is a _____.

Tpy6a [65]

Answer: The correct answer for the fill in the blank is - medium of exchange.

Explanation-

When we use paper money to pay for food, the money is a medium of exchange as we are exchanging our money with their food. So, it plays a role of medium of exchange in purchasing our food.

On the other hand, unit of account is also a feature of money but it only indicates the price of food at which we are purchasing it. Store of value is used when we store our money as a wealth, then it becomes store of value .

Hence, medium of exchange is the correct answer.
