Is anything worth believing in so strongly above public scrutiny?

If the paranormal is as real as many believers claim, shouldn't it be able to survive such public evaluation?

Should any group be allowed to make any claim at all and expect those claims to be immune from public examination?

I am not defending the rude, childish or inappropriate of any camp. I am asking why it is believers in the paranormal are so adamant that their beliefs be treated like a sacred cow.

When ice at 0.0oC melts to liquid water at 0.0oC, it absorbs, 0.334 kJ of heat per gram. Suppose the heat needed to melt 32.0 g of ice is absorbed from the water contained in a glass. If this water has a mass of 0.610 kg and a temperature of 67.0oC, what is the final temperature of the water (in C)? (Note that you will also have 32.0 g of water at 0oC from the ice).

This is confusing me.. I already solved most of my problem, solving for x and y, but now I need to know whether this triangle is acute or obtuse. It has two acute angles, yet an obtuse angle also. Which is it? Why? How do I know if another triangle is acute or obtuse?

a 45 kg girl is standing on a 150 kg plank. The plank originally at rest, is free to slide on a frozen lake, which is a flat frictionless surface. The girl begins to walk along the plank at a constant velocity of 1.50 m/s to the right relative to the plank.


1. What is her velocity relative to the ice surface?



2. What is the velocity of the plank relative to the ice surface?


Could you please explain this to me, also....I'm lost. THANK YOU.

the head of a golf club (200 g) is traveling at 55 m/s just before it strikes a 46 g ball at rest on a tee. After collision, the club head travels in the same direction at 30 m/s.

What is the speed of the ball just after impact?? explain??
