Answer:
Space junk, or space debris, is any piece of machinery or debris left by humans in space. It can refer to big objects such as dead satellites that have failed or been left in orbit at the end of their mission. It can also refer to smaller things, like bits of debris or paint flecks that have fallen off a rocket.
The mineral with Mohs hardness would be scratched because the mineral with Mohs 7 hardness is stronger than the Mohs 5 mineral. Eventually, that mineral would turn into dust if you kept rubbing it.
Answer:
ans: 4.34 × 10^(-9) N
Explanation:
mass of Mya say (m) = 65 kg
mass of spaceship say (M) = 1600 kg
universal gravitational constant(G) =6.67 × 10^(-11) Nm²/kg²
separation distance (d) = 4m
so,
gravitational force (F)= GMm/d²
=( 6.67 × 65 × 1600) / ( 10¹¹ × 4²)
= 4.34 × 10⁴ / 10¹³
= 4.34 × 10^(-9) N
