9514 1404 393

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

A student is investigating cellular transport. She fills a beaker with 250 ml of water. She places 10 drops of red food coloring
Vera_Pavlovna [14]

Answer:

The correct answer is A The student is investigating the passive transport of diffusion.

Explanation:

Diffusion is a type of transport process which helps in the transport of small molecules and gases towards their concentration gradient that"s means from region of high concentration to the low concentration region untill equilibrium is reached.

       In this question the 10 drops are red coloured food particles that are placed into the beaker, diffuses to all the regions of the beaker untill the concentration of that red colored food particle become same in all the regions to which red colored food particle diffuse.

What is the difference between a theory and a scientific fact?
seraphim [82]
Scientist, a fact is something that can be tested by anyone with the proper skill and equipment, and that repeatedly and reliably gives the same result every time. A scientific theory is a body of knowledge based on facts that describes their interaction in the simplest possible way
