Where is the magnetic south pole compared to the geographical north pole?

1 answer:

7 0

Currently, the magnetic south pole lies about ten degrees distant from the geographic north pole, and sits in the Arctic Ocean north of Alaska. The north end on a compass therefore currently points roughly towards Alaska and not exactly towards geographic north.

If gravity did not affect the pain of a horizontally thrown ball the ball would

Drupady [299]

If gravity had no effect on a ball after you threw it ... and there also
were no air to slow it down ... then the ball would continue traveling
in a straight line, in whatever direction you threw it.

That's the heart and soul of Newton's laws of motion ... any object
keeps moving at the same speed, and in a straight line in the same
direction, until a force acts on it to change its speed or direction.\

If you threw the ball horizontally, then it would keep moving in the
same direction you threw it. But don't forget: The Earth is not flat.
The Earth is a sphere. So, as the ball kept going farther and farther
in the same straight line, the Earth would curve away from it, and it
would look like the ball is getting farther and farther from the ground.

Without air resistance, the ball would reach a height of h = 31.9 m(pic 1)
The gravitational potential energy difference would be ΔU = 62.588J - 43.164J = 19,424J (pic2 + 3)
The work done by air resistance must be equal to the energy difference(pic4)
The magnitude of the air resistance: F = 0.883N

A Ferris wheel with a 15-m radius makes three complete revolutions in one minute about its horizontal axis. What is the magnitud

Kay [80]

Answer:

$1.48 m/s^2$ , upward

Explanation:

The passenger on the wheel experiences a centripetal acceleration, which is the one that keeps him in a circular motion.

The direction of this acceleration is always towards the centre of the circular trajectory: so when the passenger is at the lowest point of the ride, the acceleration is upward.

Concerning the magnitude, it is given by

$a=\omega^2 r$

where

$\omega$ is the angular velocity

r = 15 m is the radius

We need to find the angular velocity; we know that the wheel completes 3 revolutions in one minute. Each revolution corresponds to an angle of $2\pi$ rad, so the total angular displacement is
