Why couldn't the Mars Science Laboratory land using airbags to bounce to the Martian surface from a parachute?
A. The presence of liquid water made it necessary to land the rover on its wheels.
B. Scientists and engineers were concerned that the airbags could become tangled in the MSL.
C. Engineers were worried the airbags might deflate too soon.
D. The heavier weight of the MSL made airbag landing technology impractical.
Answer: D. The heavier weight of the MSL made airbag landing technology impractical.
Explanation:
Airbags have been used by NASA before to land objects on Mars such as during the Pathfinder and Spirit and Opportunity missions due to their practicality in landing in a planet like Mars with its thin atmosphere.
This however could not be used for the Mars Science Laboratory mission because the rover involved which was called Curiosity, was simply too heavy to use airbags to land.
Answer:
The heavier weight of the MSL made airbag landing technology impractical.

Explain why a hydraulic power system would be the best choice when building a device or vehicle that requires large amounts of power, citing at least three examples.
Answer:
The correct answer can include a ship’s steering system, construction vehicles, and aircraft (control systems).
Explanation:
The basic design of a hydraulic lifting system includes two pistons, a connection, tubing, and a fluid. An increased volume of fluid leads to increased contact points, so the pressure applied will increase. The force is distributed evenly to all points in an incompressible fluid. The piston that lifts the load has a larger surface area than the piston that receives the original force, and therefore the force is multiplied and can create great power.

Answer:
I think the answer is 1. hydraulic 2. pneumatic
Explanation:
Hydraulic involves the mechanical properties and use of liquids. At a very basic level, hydraulics is the liquid counterpart of pneumatics, which concerns gases. pneumatic is a branch of engineering that makes use of gas or pressurized air. Pneumatic systems used in industry are commonly powered by compressed air or compressed inert gases. A centrally located and electrically powered compressor powers cylinders, air motors, and other pneumatic devices.
