A ball is shot straight up into the air from the ground with initial velocity of 44ft/sec44ft/sec. assuming that the air resista
solniwko [45]
Convert the given in SI units.

         (44 ft/sec)(1 m/ 3.28 ft) = 13.41 m/sec

The distance traveled and the initial velocity can be related through the equation,
  
   d = (Vf)² - (Vi)²/ 2a

where d is the distance, Vf is the final velocity, Vi is the initial velocity, a is the acceleration due to gravity. Substituting the known values from the given above,

    d = ((0 m/s)² - (13.41 m/s)²)/ 2(-9.8 m/s²)

The value of d from the equation,

    d = 9.17 meters

Convert this to feet,

    d = (9.17 m)(3.28 ft / 1 m) = 30 ft

Answer: 30 ft

Choose what colors are absorbed when white light hits a red apple. (Pick all that apply.)
astra-53 [7]
A red apple absorbs all colors of visible light except red, so red light
is the only light left to bounce off of the apple toward our eyes. 
(This is a big part of the reason that we call it a "red" apple.)

Here's how the various items on the list make out when they hit the apple:

<span>Red . . . . . reflected
Orange . . absorbed
Yellow . . . </span><span><span>absorbed

<span>Black . . . no light; not a color
White . . . has all colors in it</span>

The human body is a system of systems that rely on each other to sustain a life. Explain how.
Misha Larkins [42]
The human body is connected in every way. All the organs are connected and help each other be alive. For example, the veins are connected to the heart, which help it by pumping blood and oxygen. If they weren’t there, the heart wouldn’t be able to sustain a life.
I really hope this gave you and ideas and helped you in some way:)
