The unit that is NOT a unit of mass is Newton (N). Newton is a unit of force in the International System of Units (SI).

The action that will decrease the gravitational attraction between objects A and B is increasing the distance between A and B. According to Newton's law of universal gravitation, the force between two objects is inversely proportional to the square of the distance between them.

The weight of the satellite when it is launched into orbit about the Earth at an altitude of 36,000 km will be less than 50 kN. This is because weight is the force exerted by gravity on an object, and this force decreases with distance from the Earth's center.

The weight of a woman with a mass of 60 kg on the surface of the Earth, where the gravitational field strength is approximately equal to 10 N/kg, can be calculated using the formula weight = mass x gravitational field strength. Therefore, her weight is 60 kg x 10 N/kg = 600 N.

The mass of a spacecraft that weighs 800 N on the surface of the Moon, where the gravitational field strength is approximately equal to 1.6 N/kg, can be calculated using the formula mass = weight / gravitational field strength. Therefore, its mass is 800 N / 1.6 N/kg = 500 kg.

The weight of a pencil with a mass of 50 grams (or 0.05 kg) at the surface of the Earth, where the gravitational field strength is approximately equal to 10 N/kg, can be calculated using the formula weight = mass x gravitational field strength. Therefore, its weight is 0.05 kg x 10 N/kg = 0.5 N.
