Answer:

C. the correct Technology cannot support this mission  

Explanation:

There is not enough technology to make it possible to plan a mission safely for this distance. What can be done to study this planet is to visualize it with super powerful telescopes and to use simulations to analyze and identify the dynamics of the axis of rotation of the planet. These dynamics determine how much a planet tilts on its axis and how that angle of inclination evolves over time.

How does salt help melt the road?​
QveST [7]

Lower the melting point

Explanation:

Salts helps to melt road by lowering the melting point. It acts as an impurity and generally, impurities low the melting point of substances.

Salts are used as an antifreeze.

  • Water freezes at 0°C and forms ice/snow which can impede human and vehicular movement.
  • When salt is added, it causes the depression of the freezing point by lowering it further.
  • The freezing point is pegged back at -6°C.
  • This way it takes more low temperature to freeze the water.
  • The salt acts as an impurity and causes the depression of melting point and widening of the melting range.
