Mars Global Surveyors (MGS) and later orbiters found the following  minerals on the  Martian surface;

  • Phyllosilicates
  • Carbonate
  • Sulfates
  • Iron oxide

The Mars Global Surveyors (MGS) and later orbiters suggest that the Martian crust contains a higher percentage of volatile elements such as Sulphur and chlorine than the Earth's crust does.

These scientists also conclude that the most abundant chemical elements  in the Martian crust are those found in Igneous rock.

These elements include the following;

  • Silicon,
  • Oxygen,
  • Iron,
  • Magnesium,
  • Aluminum,
  • Calcium, and
  • Potassium.

They also, suggest that hydrogen is found in ice (water) while carbon is found in carbon dioxide and carbonates.

From the given options the minerals found in Martian surface include;

  • Phyllosilicates ------ these are sheet of silicate minerals
  • Carbonate
  • Sulfates
  • iron oxide

Suppose this comet were to hit the earth at 40000 km/h and fuse with it. by how much would it change our planet's velocity? (the
sattari [20]
  <span>change in velocity = final velocity - initial velocity = v - u 

for comet: 
uc = initial velocity of comet (before impact) 
vc = final velocity of comet 
mc= mass of comet 

uc = 40000 kmph 
vc = ? 
mc= 10 x 10^14 kg 


for probe: 

up = initial velocity of probe (before impact) 
vp = final velocity of probe 
mp= mass of probe 

up= 37000 kmph 
vp= ? 
mp= 372 kg 

Now, 
by principle of conservation of momentum 

(mc x uc) - (mp x up) = (mc x vc) + (mp x vp) 

Since probe is in comet after collision, vp= vc = V 

then, 

(mc x uc) - (mp x up) = V (mc + mp ) 
V = [(mc x uc) - (mp x up)] / (mc + mp ) 

= ((10 × 10^14 × 40000) - (372 × 37000)) ÷ ((10 × 10^14) + 372) 

= ??? 

then, 

change in velocity of the comet = ??? - (40000) =

When it reaches an altitude of 3600 m, where the temperature is 5.0∘C and the pressure only 0.68 atm, how will its volume compar
dalvyx [7]

Answer:

The question was incomplete. Here is the complete question.

Explanation:

A helium-filled balloon escapes a child’s hand at sea level and 20.0C. When it reaches an altitude of 3600 m, where the temperature is 5.0∘C and the pressure only 0.68 atm, how will its volume compare to that at sea level?

The ideal gas equation:

PV = nRT

P = absolute pressure

V = Volume of a gas

n = no of moles of a gas

R = ideal gas constant

T = Absolute temperature of a gas

For initial and final states:

P_{i}V_{i} = nRT_{i}   \\P_{f}V_{f} = nRT_{f}   \\\frac{V_{f} }{V_{i} } = \frac{P_{i}T_{f} }{P_{f}T_{i} }

= 1.4

Which of these has the most inertia?
VashaNatasha [74]

Answer:

A. a parked bus

Explanation:

Because a parked bus probably has the most mass out of these 4 and as we know, mass is that quantity that is solely dependent upon the inertia of an object. The more inertia that an object has, the more mass that it has. A more massive object has a greater tendency to resist changes in its state of motion.
