When a brown bear eats a salmon, does the bear acquire all the energy contained in the body of the fish? Why or why not? What implications do you think this answer would have for the relative abundance (by weight) of predators and their prey?

Best answer = 10 points!

A child slides down a hill on a toboggan with an acceleration of 1.8 m/s^2.

If she starts at rest, how far has she traveled in 1.0 s?

I got 1.8 m but it was incorrect... how?

What's your opinion on EVP's?

I was a skeptic for quite awhile...But...A few friends and me went to a cemetery with a tape recorder and well you know what happens next...

We were able to "catch" an EVP...It was absolutely NOT a
"pick-up" off some radio frequency or a simple sound...This was a full spoken sentence and a remark to a smart a-s-s comment we made while we were there.

Again-what's your opinions on EVP's in general? Is this proof enough for me-that there is in fact life after death?

How else do I explain our evp?

Not just referring to '69.

Twice in 1969 (Apollos 11 & 12).
Twice in 1971 (Apollos 14 & 15).
Twice in 1972 (Apollos 16 & 17).

Personally, I don't believe this to be a hoax at all. But I'm curious to see how many people actually do, and why.

the theorem in my book is: If two points are each equidistant from the end points of a segment (I got this part), then the two points determine the perpendicular bisector of that segment (I am confused on the part after the comma). THANKS SOOO MUCH!!!

Use Quine’s method to classify each of the following formulas as a
tautology, a contradiction, or a contingency.
(a)
(((p ∧ q) → r) ∧ (p → q)) → (p → r)
(b) ((p ∨ q) ∧ (p → r) ∧ (q → s)) → (r → s)

How come the Hubble Space Telescope, being capable, can photograph objects billions of lightyears away from Earth with great clarity and detail (stars, mok globules, etc.), while it can only get 'this close' when photographing Mars, or Europa or other 'much closer' objects in our own backyard?

Why even the need to send orbiting crafts to these nearby objects to get an - even then - not so sharp images?

Or maybe NASA is not providing the public with such 'ala google-earth' photos of our neighboring planets?

(*head scratch*) Refractive problems, hyperopia perhaps?
