Answer: D)The distance from Earth and mass of ISS exert negligible gravitational force on the astronaut.
Explanation:
The distance from Earth and mass of ISS exert negligible gravitational force on the astronaut. Gravity is a very weak force and varies with mass and the inverse square of distance. The astronaut's distance from Earth and the relative small mass of ISS result in gravitational force near zero.

Having a pH of 6.3 for a kiddie pool would be considered as acidic. You need to increase this value to keep it safe for use. The safest pH level would be from 7.2 to 7.4. This would be safe for the skin of the one who uses the pool. Hope this answers the question.
Answer:
a) [NH2]-,
b) [O]2-
c) [Cl]-
Explanation:
The conjugate base is the base member (X⁻) of a weak acid (HX). In other words, the conjugate base is the remaining substance due to the proton loss in the acid HX.
a) For NH₃, (HX; X: NH₂⁻), conjugate base is NH₂⁻. In the format, <em>[NH2]-</em>.
b) For OH⁻, (HX; X: O²⁻), conjugate base is O²⁻. In the format,<em> [O]2-</em>.
c) For HCl, (HX; X: Cl⁻), conjugate base is Cl⁻. In the format, <em>[Cl]-</em>.
I highly believe it would be D
Because yes it does happen above water but it’s not just that, and the other two don’t seem correct. So sorry it’s not correct but I believe it is D
