You can tell that it has reached its terminal velocity when D) the leaf is falling with a constant velocity as you are watching the leaf fall. The terminal velocity is a point of condition when an object's speed equalize the force of gravity. The terminal velocity condition could occur if there is no acceleration to the object's speed<span>.</span>

Answer:

0.0231 m/s

Explanation:

Given the question :

A small toddler is playing in his yard. Over the course of 29.01 s, he walks 2.099 m S before turning N and walking 1.429 m. What is his average velocity?

Distance walked south = 2.099 metre

Time taken = 29.01s

Distance walked north = 1.429 metre

Average Velocity = Displacement / time

The Displacement is hence,

(2.099 m - 1.429m) = 0.67m

Average Velocity = 0.67m / 29.01s

Average Velocity = 0.02309 m/s

Average Velocity = 0.0231 m/s

From what three regions do most of the small objects in the universe come?
Ivenika [448]

Answer:

Scientists who study the Sun usually divide it up into three main regions: the Sun's interior, the solar atmosphere, and the visible "surface" of the Sun which lies between the interior and the atmosphere. There are three main parts to the Sun's interior: the core, the radiative zone, and the convective zone.

Explanation:

Hopefully this helps :)

Select the correct answer. What do scientists use to determine the temperature of a star? A. Thermometer B. Distance from Earth
Vladimir79 [104]

Answer:

Color

Explanation:

Thus, for stars, considering them as “black bodies”, we can get an approximate figure for their temperature by measuring their dominant frequency (color). Technically scientists measure the brightness of the blue light and that of red light from the star, and from this they can calculate the temperature of the star.
