Answer:
a) The module's acceleration in a vertical takeoff from the Moon will be 
b) Then we can say that a thrust of
won't be able to lift off the module from the Earth because it's smaller than the module's weight (
).
Explanation:
a) During a vertical takeoff, the sum of the forces in the vertical axis will be equal to mass times the module's acceleration. In this this case, the thrust of the module's engines and the total module's weight are the only vertical forces. (In the Moon, the module's weight will be equal to its mass times the Moon's gravity acceleration)

Where:
thrust 
module's mass 
moon's gravity acceleration 
module's acceleration during takeoff
Then, we can find the acceleration like this:


The module's acceleration in a vertical takeoff from the Moon will be 
b) To takeoff, the module's engines must generate a thrust bigger than the module's weight, which will be its mass times the Earth's gravity acceleration.

Then we can say that a thrust of
won't be able to lift off the module from the Earth because it's smaller than the module's weight (
).
It is not possible to explain the interaction of the rod and pieces of paper as a gravitational interaction.
<h3>What is Gravitational interaction?</h3>
This is defined as the interaction between a particle or body resulting from their mass. This type of interaction is usually weak and occurs in all distances possible.
It is not gravitational interaction, because the rod attracts paper only against the gravitational force of the earth and there is no attraction between both bodies under a different condition.
This is therefore the reason why it is not possible to explain the interaction of the rod and pieces of paper as a gravitational interaction.

Answer: Temperature inversion
Explanation: Temperature inversion is a reverse of the normal temperature flow or distribution of the air,it usually causes temperature to rise as altitude increase towards the troposphere instead of reduction of temperature.
Temperature inversion is caused when warm,dense air flow above cold,less dense air. Temperature inversion is hazardous to man as it traps pollutants close to the Earth surface,this condition limits vertical circulation.
