You are standing on Earths equator so Which way is Polaris the North star?

If you are right at the Equator, you will not be able to see Polaris. If you could, it would be right on the horizon, but ground haze and obstructions would almost certainly hide it from view.

How do you measure latitude by polaris?
Polaris (or the North Star) is almost directly above the North pole. This means that when you stand on the north pole and look directly up, you will see Polaris. This also means that when you stand at the equator and look directly north, you will see Polaris on the horizon. You can not see Polaris from the Southern Hemisphere. The angle Polaris is above the horizon is equal to the degree latitude that you are standing on. Therefore at the equator, Polaris is 0 degrees above the horizon and at the north pole, Polaris is 90 degrees above the horizon.
When is Polaris directly overhead?
Polaris always sits within about 1/2 degree from the point in the sky that's the same angle above the northern horizon as your latitude. For example, if you're standing at the north pole, the point is directly over your head, and if you're anywhere on the equator, the point is on the horizon directly north of you.
Why will you weigh more at the north pole than the equator?
An object weighs more at the north pole than at the equator for two reasons: Distance from the center of the earth, and earths rotation. The earth is not perfectly spherical, it's an oblate, wider at the equator than at the poles because it's spinning. As such you are slightly closer to the center of the earth when standing at the poles, than at the equator. Being slightly closer means that the gravity is slightly stronger, making you weigh more. Also at the equator you are spinning around the earths' axis with the rest of the planet, and this acts to reduce the measured weight of an object.
Where in the sky is the north star when viewed from the equator?
It is not visible at or south of the Equator. Theoretically , it would appear on the horizon. Remember the Pole Star is overhead at 90 degree N. (The North Pole). So when you have reached the Equator, your angle has changed by 90 degrees because you are now at 0(zero) degrees. So viewing the sky Polaris (Pole Star) will has now changed its angle by 90 degrees. So from being overhead, a 90 degree angle will be the horizon. You don't see Polaris at the Equator, because of the density of the atmosphere, dust and dirt and moisture in the atmosphere.

What is the altitude of Polaris as seen from New York City if the terrestrial coordinates are 41 degrees north 74 degrees west?
Polaris makes a little circle of about 1/3° radius around the celestial north pole every day. But we don't notice that, and it appears to mark the pole itself. So the altitude of Polaris is essentially equal to the observer's north latitude. If he's standing 41° north of the equator, then he'll see Polaris at roughly 41° above his northern horizon.
When is Polaris directly overhead?
Polaris always sits within about 1/2 degree from the point in the sky that's the same angle above the northern horizon as your latitude. For example, if you're standing at the north pole, the point is directly over your head, and if you're anywhere on the equator, the point is on the horizon directly north of you.
Why is Polaris at its highest latitude in the Arctic Circle?
The Earthg's north pole points very close to Polaris in the sky. So Polaris is directly over your head when you stand at the north pole, it's on your horizon when you stand on the equator, and it's somewhere between your horizon and the point directly over your head when you stand somewhere between the north pole and the equator.
Which part of America can see Polaris at night?
You can see it from anywhere in North America, and the parts of South America that are north of the equator.

What appears to revolve around Polaris due to earth's rotation?
Due to the vast distance between the earth and polaris, the earths axis of rotation essentially lines up with polaris at all times, so when the stars are visible, and viewed from the north pole, the earths rotation causes the stars to appear to rotate around polaris.
