Answer:

2) Earth’s geographic North Pole is close to the magnetic south pole.

3) Magnets allowed to move freely align themselves to point north.

5) The north pole on a compass is attracted to Earth’s magnetic south pole.

Hope this helped:)

It doesn't. It points to the Earth's MAGNETIC pole. There's only a very small part of the Earth's surface where the geographic pole is in exactly the same direction, and there are places where there's a huge difference. For example, I've worked in parts of Alaska where compasses point WEST !

After a plant or animal dies the 14C content decreases with a half-life of 5730 years. If an archaeologist finds an ancient fire

Shalnov [3]

Answer:

age of the site is 15411.75 years old

Explanation:

Given data

plant or animal dies = 14C

time period = 5730 year

carbon = 15.5%

to find out

age (in years) of the ancient site

solution

we know that Final value = Initial value × $0.5^{n}$

here n is half life passed

so for 15.5%

15.5% = 100% of $0.5^{n}$

0.155 = 1 × $0.5^{n}$

now take log both side

log 0.155 = log $0.5^{n}$

n = log 0.155 / log 0.5

n = 2.68966

we know here 5730 years in half life

so for 2.68966 half-lives = 2.68966 × 5730 = 15411.7518

age of the site is 15411.75 years old

When only several competitors in an industry maintain most of the sales of those items, it is considered a(n) Industry of Social

Alexeev081 [22]

Answer:

Oligopoly

Explanation:

An oligopoly is the structure of the market that is characterized by the domination of a few firms or industries. Other small firms also operate in the same market, but the power concentration is associated with few firms only. Interdependency among the firms helps in planning and strategy making to introduce new ideas to increase the market activities. The competition in the market is reduced when a few of the firms dominate the market. It results in an increase in the price of commodities.

A meteor moving 468 km per minute traveling in a south-to-north direction passed near Earth in 2013. Does this statement describ

Thepotemich [5.8K]

Answer:

this statement describes meteor's velocity,

because velocity is a vector quantity which has both magnitude as well as a specific direction and here the meteor's direction is specified in the statement hence we conclude that this statement describes meteor's velocity as well as speed too.
