Web spiders and oscillations all spiders have special organs that make them exquisitely sensitive to vibrations. web spiders detect vibrations of their web to determine what has landed in their web, and where. in fact, spiders carefully adjust the tension of strands to "tune" their web. suppose an insect lands and is trapped in a web. the silk of the web serves as the spring in a spring-mass system while the body of the insect is the mass. the frequency of oscillation depends on the restoring force of the web and the mass of the insect. spiders respond more quickly to larger - and therefore more valuable - prey, which they can distinguish by the web's oscillation frequency. suppose a 15 mg fly lands in the center of a horizontal spider's web, causing the web to sag by 4.0 mm .

assuming that the web acts like a spring, what is the spring constant of the web?

Asmall metal bar, whose initial temperature was 10° c, is dropped into a large container of boiling water. how long will it take the bar to reach 70° c if it is known that its temperature increases 2° during the first second? (the boiling temperature for water is 100° c. round your answer to one decimal place.) sec how long will it take the bar to reach 98° c? (round your answer to one decimal place.)

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.
