Answer
3× 105 kg in the calculation represents the mass of the space shuttle.
Explanation
When calculating the force of gravity of on the shuttle, the formula used is ; force of gravity=mg.  m represents the mass of the object(shuttle) and g is the acceleration of the shuttle due to gravity. g= 9.81 m/s².Multiplying the mass of the shuttle by 9.8 gives the force of gravity
Answer:The correct answer :
The mass of the space shuttle
Explanation:
Force is defined as product of mass of an object and acceleration with which it is moving.
Force = Mass × Acceleration
Where , Mass is measured in kilograms.
Acceleration is measured in meter per second squared
The value [tex]3\times 10^5 kg[/tex] represents the mass of the space shuttle.Since the unit mentioned after the numeric value is kg and mass is the quantity which measured in the kg.
