Mystery Spot and Physics

Mystery spot is a tourist attraction located near Santa Cruz , California. It is a place where the laws of physics and gravity do not apply.
The Mystery Spot is a gravity hill, a tilt indused visual illusion. In the tilted room of the mystery spot , misperceptions of the height and orientation of objects occur. Explain.

(Asked by G Saranya)

Answer:

The question on gravity hills (also called magnetic hills) is already answered. Please refer to http://askphysics.com/gravitation/magnetic-hills-gravity-hills/

A question based on the theory of machines

†ђe fig below shows a tilt hammer ahinged at o, with its head resting on top of †ђe pile Bm †ђe hammer including †ђe arm OA, has a mass of 25kg.its centre of gravity Gis 400mm horizontally. from O Ąπϑ its radius of gyration about an axis through G parallel to †ђe axis of †ђe pin 00000 is 75mm. †ђe pile has a mass of 135kg. †ђe hammer is raised through 45• To †ђe position shown in dotted lines Ąπϑ released. On striking †ђe pile there is no rebound. Find †ђe angular velocity of †ђe hammer immediately before †ђe impact Ąπϑ †ђe linear velocity of †ђe pile after impact. Neglect any impulsive resistance offered by †ђe earth into Ψђíçђ †ђe pile is being driven. [Thank you]

How earths tilt causes seasonal change?

Zeenath PV asked: how earths tilt causes seasonal change?

Answer:

image The climate on earth is mainly determined by the distance from sun and how much sunlight (and heat radiations) is received by earth. The relative duration of day and night as well as the climate is greatly dependant on the tilt of the earth’s axis with respect to its plane of orbit around sun and the elliptical shape of earth
