Right now (late 2015), the difference is about 256 miles.
The geographic north pole is the point where the north end of the
Earth's rotation axis sticks out of the ground. As long as the Earth
continues to spin on the same 'pencil', the geographic poles don't move.
The magnetic north pole is the point on Earth that magnetic compasses
point to. The magnetic poles are the result of the flowing, shifting liquid
iron in the Earth's core, and they move. The magnetic north pole is presently
somewhere in the Canadian Arctic territory, about 256 miles south of the
geographic pole, and moving westward towards Russia at about 35 miles a year.
Answer:
The result is a vector perpendicular to the xy plane: 23.38 k
Explanation:
The cross product of two vectors r and s is defined only in three-dimensional space and is denoted by r × s. The cross product is defined by the formula:
r × s =║r║·║s║· Sin θ· n
where θ is the angle between r and s in the plane containing them, ‖r‖ and ‖s‖ are the magnitudes of vectors r and s, and n is a unit vector perpendicular to the plane containing a and b in the direction given by the right-hand rule.
So, the result is:
r × s = 4.40 * 7.45 * Sin (134.5°) k = 23.38 k
C. Science is objective, and pseudoscience is subjective
The answer would be D) Kinetic friction because kinetic means during and in motion and happening/occurring so since the box is moving now across the floor, its in motion so that's why its D).
yes but all of these are correct answers
