Which of following is true of compasses?
A compass has both a south pole and a north pole :)
What are two things that can interfere a compass finding north?
Two factors that can interfere with a compass finding true north are magnetic declination and nearby magnetic fields. Magnetic declination refers to the angle difference between true north and magnetic north, which varies by location and can lead to inaccuracies. Additionally, nearby magnetic materials, such as metal objects or electronic devices, can create local magnetic fields that distort the compass needle's alignment, causing it to point away from true north.
Why does the portable sundial need a compass?
The compass on a portable sundial helps the user align the sundial accurately north-south, which is crucial for it to give accurate time readings based on the sun's position. By pointing the sundial's gnomon (the part that casts a shadow) towards true north using the compass, the sundial can accurately indicate the time.
What invention uses gravity to find direction?
The invention that uses gravity to find direction is the compass, specifically the type known as a gravity compass or pendulum compass. This device relies on a pendulum or a similar mechanism that aligns itself with the gravitational pull of the Earth, allowing it to indicate true north. By understanding the gravitational field, the compass provides navigational assistance, helping users determine their bearing relative to the Earth's magnetic poles.
Is not true about the invention of the compass?
One common misconception about the invention of the compass is that it was created in Europe. In reality, the compass was first developed in China during the Han Dynasty around the 2nd century BC, initially for divination purposes. Its use for navigation was later adopted and refined in maritime cultures, including those in Europe and the Islamic world. This misunderstanding highlights the importance of recognizing the compass's origins and its evolution across different cultures.

What is 271 degrees true as a compass bearing?
compass bearing 271
Are the cardinal directions on a compass rose true or magnetic?
True
What is a True compass bearing?
The definition of a true compass bearing - A true bearing is measured in relation to the fixed horizontal reference plane of True North, that is using the direction towards the geographic North Pole as a reference point.
What compass bearing is south?
The definition of a true compass bearing - A true bearing is measured in relation to the fixed horizontal reference plane of True North, that is using the direction towards the geographic North Pole as a reference point.
Which of following is true of compasses?
A compass has both a south pole and a north pole :)
What does a compass needle point do?
It points to true north.
You can draw a regular hexagon using only a straightedge and compass?

The arrowhead of a compass always point north?
True north is the direction indicated by the Earth's axis of rotation, while magnetic north is the direction indicated by the compass needle. The arrowhead of a compass points towards magnetic north, not true north.
True or false trisecting a line segment requires a ruler and compass since a straight edge and compass will not be sufficient?
False
