Quizizz: The Martian Part 3

What is a sign that you have colonized a planet?

• Establishment of permanent settlements and infrastructure.
• Once you grow crops.

• Establishment of temporary research stations.

• Discovery of alien life forms.

What caused the explosion of the probe (loaded with supplies for Mark) that the US launched? (you must pick 2)

• Weather conditions during launch
• Insufficient fuel in the probe
• The food liquified and shifted the weight and caused an unbalanced load

• Technical issues with ground control
• NASA wanted to save time by omitting inspections.

After the explosion of the supply probe, how did Mark stretch his rations?

• He went from eating 3 rations per day to eating 1 ration every 3 days.

• By trading his rations with other crew members.
• By consuming all his supplies at once.
• By growing food in a makeshift garden.

What country is becoming a major contributor to space exploration and lends their rocket?

• China
• Russia
• Brazil
• India

How was Mark able to lift the 300 kg nose cap?

• Mark was able to lift the 300 kg nose cap using a mechanical advantage.
• Mark used a crane to lift it.
• Mars has less gravity than Earth and is only 38% of Earth's so the cap only weighs about 100 kg

• Mark used a team of people to lift it.

Why did Mark pass out as he took off?

• Mark was dehydrated from his long stay on Mars.

• Mark was feeling dizzy from a recent illness.
• Mark was distracted by a loud noise during takeoff.
• He experienced a force of 12 G which makes all the blood pool in his feet.

Which of Newton's laws did the Hermes use to slow down and Mark used to play "Iron man"?

• Newton's Second Law: Force = mass x acceleration (F = ma)

• Newton's Law of Universal Gravitation
• The 3rd law: Every action has an equal but opposite reaction.

• Newton's First Law: an object in motion stays in motion while an object at rest stays at rest.

What better plan was purposed to save Mark? (the plan had 2 parts so you must select 2 answers)

• The Hermes would accelerate before reaching Earth & then use a gravitational assist to slingshot back to Mars.

• The Chinese would send supplies to Hermes via their rocket, the Taiyang Shen.

• Implement a strategic intervention then establish a support system.

• Mark would go to the Schiaparelli Crater to live until the next mission came to rescue him.

• Mark would go to the Schiaparelli Crater and pilot the MAV back to Earth.

Why does Mark need to lose so much weight from his ship? (you must pick 2 options)

• Improve fuel efficiency, Enhance speed and maneuverability
• Improve onboard flight control.

• The MAV was only designed to enter a low orbit.

• Increase cargo capacity
• The Hermes can't enter Mar's orbit because it doesn't have enough fuel to escape its gravity.

Why was it all right to remove the nose cap and replace it with a tarp?

• Mar's atmosphere is so thin that it wouldn't have much air resistance.

• The tarp is lighter and easier to handle than the nose cap.
• The nose cap was damaged beyond repair.
• The tarp is more aesthetically pleasing than the nose cap.
