Which of the following statements are true? a. earth's gravity has no effect on astronauts inside the international space station. b. an astronaut's mass is greater on earth than on the moon. c. an astronaut's weight is the same on the moon as on earth. d. an astronaut's mass is the same on the international space station as it is on earth. e. none of these statements are true.

The given statement "An astronaut's mass is the same on the International Space Station as it is on Earth" is true.

Option D

Explanation:

There is usually a slight difference between mass and the weight of an object. The difference is that the mass of any object is independent of its acceleration due to gravity or gravitational influence of the planet where it is present.

Similarly, the weight of any object will be influenced by the gravitational force of that planet as the weight is directly proportional to the acceleration due to gravity of that planet.

So, the other three options are false and those three options states that weight of an object on Earth is equal to the weight of that object on any other planet. This is not true. So, the fourth option related to the mass of an astronaut in and outside Earth is true as it is equal theoretically.
