Which features on mars point to the possibility of liquid water on the planet?

2 answers:

7 0

In 2011 NASA researchers identified features on Mars known as Recuring Slope Lineae ( or RSL ). RSL are relatively dark and narrow features.They are thought to be a signs of salty liquid water on Mars. One hypothesis for RSL formation is that they form when underground bodies of salty water leak into the surface.
Answer: Recuring Slope Lineae.

HELP I NEED THIS ANSWERED AS FAST AS POSSIBLE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

WITCHER [35]

Displacement is d

Vf² = Vi² + 2 g d

(-20²) = (+10²) + 2 (-9.8) d

-19.6 d = 300

d = -15.3 m

negative means lower

time is t

d = Vi t + 1/2 g t²

-15.3 = 10 t + (-4.9) t²

4.9 t² - 10 t -15.3 = 0

t = 3.06 s

Hope this helps -John

A particular planet has a moment of inertia of 8.26 × 1036 kg⋅m2 and a mass of 6.54 × 1022 kg. Based on these values, what is th

SVEN [57.7K]

Answer: Correct answer is B = 1.776933× $10^{7}$

Explanation:

Given :

Moment of inertia I = 8.26× $10^{36}$ kg $m^{2}$

Mass of planet m = 6.54× $10^{22}$ kg

Also, Planet is solid sphere so that, Moment of inertia is I = $\frac{2}{5}$ m $R^{2}$ =0.4m $R^{2}$

Where R is radius of planet

Putting into calculation

We get,

I = $\frac{2}{5}$ m $R^{2}$

8.26× $10^{36}$ = 0.4×6.54× $10^{22}$ × $R^{2}$

8.26× $10^{14}$ = 2.616 $R^{2}$

3.15749235× $10^{14}$ = $R^{2}$

R = 1.776933× $10^{7}$

Thus, Correct answer is B = 1.776933× $10^{7}$

In order from largest to smallest these terms are:UniverseGalaxySolar systemStarPlanetMoonAsteroidWe can generally say that a Moon is larger than an asteroid however some moons are quite large while others are smaller than many known asteroids. Asteroids are small rocky bodies that orbit the Sun, while moons are objects that orbit planets. Jupiter and Saturn have attracted many objects out of the asteroid belt and gathered them as moons.

asambeis [7]

Answer:

B. constant pressure, isothermal, adiabatic

Explanation:

A quantity of an ideal gas is compressed to half its initial volume.

The process may be adiabatic, isothermal or occurring at constant pressure.

Adiabatic-constant heat

Constant pressure or isobaric

Isothermal or constant temperature

An external agent is a system that does work on a system or a machine.

This external agent applies force , or changes the state of the body it is acting on.

In order of the work required of an external agent, least to greatest

The following processes will be arranged.

constant pressure, isothermal, adiabatic
