In a given cartesian coordinate system a particle is in the position (initial vector position) ( 9.2 , 3.1 ) meters. After 10 se
vesna_86 [32]

Answer:

Thus, the average velocity is 9.73 m/s.

Explanation:

The velocity is given by the rate of change of position.  

initial position, A = (9.2, 3.1) m

final position, B = (72.2, 77.2) m

time, t = 10 s

The velocity is given by

\overrightarrow{v} =\frac{\overrightarrow{B}-\overrightarrow{A}}{t}\\\overrightarrow{v}=\frac{(72.2-9.2)\widehat{i} - (77.2-3.1)\widehat{j}}{10}\\\overrightarrow{v}=\frac{63 \widehat{i} - 74.1\widehat{j}}{10}\overrightarrow{v} =6.3 \widehat{i} - 7.41 \widehat{j}\\v =\sqrt{6.3^{2}+7.41^{2}}v = 9.73 m/s

ella [17]

In infrared satellite images, land appears black and clouds appear white. C

<h3>What are infrared satellite images?</h3>

Infrared satellite images are images produced as a result of electromagnetic radiations reflected or emitted from a target surface in the infrared position of the electromagnetic spectrum.

On infrared images, the clouds emit very bright white color because of the low temperature and the land appears to be black because of the hot temperature.

Therefore, in infrared satellite images, land appears black and clouds appear white. C

What feature of the solar system separates the terrestrial planets from the jovian planets?
NeX [460]

Jovian Planets have low density and no Earth like things, like the terrestrial planets.

All of the planets in our solar system,except Pluto—are categorized as either terrestrial (like Earth) or jovian (like Jupiter) planets

Terrestrial planets:

  • The planets Mercury, Venus, Earth, and Mars are all terrestrial. These planets are both physically and mass-wise quite small.
  • A terrestrial planet has a dense interior of metals and a stable rocky surface. These planets are warmer than planets farther from the sun because they are closer to the sun in the solar system.

Jovian planets:

  • Saturn, Uranus, Neptune, and Jupiter are examples of jovian planets. These planets are bigger and heavier.
  • The surfaces of Jovian planets are not solid. Due to their size and composition, which is primarily gases, they are sometimes referred to as gas giants.
  • Only in the deepest regions of the Jovian planets' cores can one find trace amounts of rocky elements. Jovian planets are cooler because they are farther from the sun than terrestrial planets in the solar system.
