Earth's climate systems are driven by the electromagnetic radiation from the sun, as wells as its reflection, absorption, storag
ivann1987 [24]

Answer:

(A) True

Explanation:

The sun is producting the electromagnetic radiation which is the primary energy source on Earth and the driver of the entire climate system.

In general the sun is the source of energy that drives all life on Earth. This energy governs the weather, ocean currents and the hydrological cycles.

Without the continuous influx of sunlight and heat, life on Earth would cease to exist. The sun sets off the hydrological cycle, causing it to constantly evaporate into the atmosphere, from which it falls back to Earth.

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

It is difficult to define Primates according to the presence or absence of certain distinguishing anatomical or behavioral trait
Sunny_sXe [5.5K]

Answer:

The correct answer is - true.

Explanation:

Primates are the third diverse group of mammals after rodents and bats. It is considered that it has diverged from other terrestrial mammals about 65 million years ago.

Defining and identifying the primates on the basis of certain anatomical and behavioral traits is not an easy task. There are almost 400 living species of primates are known.
