Just about every strand of ocean it
that Estas looked at was touched in
some way. "Every species in the
coastal zone is influenced in one
way or another by the ecological
efects of sea otters" he concludes
Thus in removing sea otters from
the North Pacric humanity - in its
pursuit of fur for hats, gloves and
coats-had not only gevously
endangered the species, it had
disrupted a large chunk of the
marine en moment in the Pacific
and for good measure-damaged
our ability to deal with the impact of
rising carbon diode levels on our
planet
The word touchedhas a negative connotation
as the author uses it. Which other selection BEST
emphasizes that connotation?

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 710 n/m. it is initially at rest on an inclined plane that is at an angle of θ = 23° with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is μk = 0.19. in the initial position, where the spring is compressed by a distance of d = 0.16 m, the mass is at its lowest position and the spring is compressed the maximum amount. take the initial gravitational energy of the block as zero. a) what is the block's initial mechanical energy? b) if the spring pushes the block up the incline, what distance, l, in meters will the block travel before coming to rest? the spring remains attached to both the block and the fixed wall throughout its motion.

Aray of light traveling parallel to the principal axis of a concave mirror will be reflected through the mirror's

A26 cm object is 18 cm in front of a plane mirror. a ray of light strikes the object and is reflected off the mirror at a 42-degree angle. what is the angle of reflection? degrees what type of image is formed? what is the size of the image? cm
