100% would be red because if you take your chart, you would put Rw and Rw on the columns. which would lead to all 4 boxes being, Rw, Rw, Rw, Rw.

Answer:

  • time: 1.122 seconds
  • range: 10.693 m
  • maximum height: 1.543 m

Explanation:

<u>Given</u>:

  runner is launched at 30° angle to horizontal at 11 m/s

  acceleration due to gravity is g = -9.8 m/s²

<u>Find</u>:

  runner's hang time

  runner's distance to the landing point

  runner's maximum height

<u>Solution</u>:

The (horizontal, vertical) speed components will be ...

  (11 m/s)(cos(30°), sin(30°)) = (5.5√3 m/s, 5.5 m/s)

The time of flight can be found from the height formula:

  h(t) = 1/2gt² +vt . . . . . . where v is the vertical speed at launch

The time we're concerned with is the time when h(t)=0 and t>0.

  0 = -4.9t^2 +5.5√3t = t(-4.9t +5.5√3)

The second factor is zero when ...

  t = (5.5√3)/4.9 ≈ 1.122 . . . seconds hang time

__

The distance to the landing point will be the product of horizontal speed and hang time:

  d = (5.5 m/s)(5.5√3/4.9 s) ≈ 10.693 m . . . . distance to landing

__

The maximum height can be found from the formula (based on conversion of kinetic energy to potential energy) ...

  h = v²/|2g| = (5.5 m/s)²/(2(9.8 m/s²)) ≈ 1.543 m . . . . maximum height

2. An unripe green fruit changes color when it ripens. The reason being:​
kirill115 [55]

Answer:

hope it helps

Explanation:

The green colour of the unripe fruit is due largely to the presence of chlorophylls, and the development of different colours during ripening is due to the disappearance of these pigments and the synthesis of carotenoids.

Group the following into the appropriate range of measurement.
Vesna [10]

Answer:

Hydrogen atom & glucose molecule --- atomic.

Herpesvirus, DNA --- ultramicroscopic.

Protozoan, Rickettsia - microscopic.

Roundworm and algae --- macroscopic

Explanation:

1) Hydrogen atom & glucose molecule --- atomic.

The atomic size level, which interacts with atoms as well as small molecules, is much lower than the ultramicroscopic range.

2) Herpesvirus, DNA --- ultramicroscopic.

Ultramicroscopic particles are very tiny structures that cannot be seen using a conventional optical microscope, necessitating the use of an electron microscope. Viruses and DNA falls into this group since they are much smaller than tiny species like bacteria.

3) Protozoan, Rickettsia - microscopic.

Microscopic species are much smaller than macroscopic organisms because they cannot be observed by the naked human eye and must be viewed through a microscope. The size range for microscopic particles is ( 10^3  \ \ to  \ \ 10^{10}), which contains protozoans and Rickettsia (a gram-negative, non-motile bacteria genus).

4) Roundworm and algae --- macroscopic

Naked eyes can see macroscopic organisms; for example, several types of circular worms and algae can be seen by them.
