Which sentence from the article supports the idea that the visible spectrum is more limited in marine animals than humans? a most bioluminescent organisms are found in the ocean, including bioluminescent fish, bacteria and jellies. b most marine bioluminescence is blue-green, which is easier to see in the deep ocean. c most organisms, however, flash their light for less than a second to about 10 seconds. d most fish can only see blue light, so loosejaws have an enormous advantage when they light up a surrounding area.

Amass attached to a spring is displaced from its equilibrium position by 5cm and released. the system then oscillates in simple harmonic motion with a period of 1s. if that same mass–spring system is displaced from equilibrium by 10cm instead, what will its period be in this case? a mass attached to a spring is displaced from its equilibrium position by and released. the system then oscillates in simple harmonic motion with a period of . if that same mass–spring system is displaced from equilibrium by instead, what will its period be in this case? a) 0.5sb) 2sc) 1sd) 1.4s

Aballoon is rising vertically upwards at a velocity of 10m/s. when it is at a height of 45m from the ground, a parachute bails out from it. after 3s he opens his parachute and decelerates ata a constant rate 5m/s.when. (a) what was the height of the parachutist above the ground when he opened his parachute? (b)how far is the parachutist from the balloon at t=3s? (c)with what velocity does the parachutist hit the ground? (d)after how long does the parachutist hit the ground after his exist from the balloon?
