Answer:
K = G Mm / 9R
Explanation:
Expression for escape velocity V_e = 
Kinetic energy at the surface = 1/2 m V_e ²
= 1/2 x m x 2GM/R
GMm/R
Potential energy at the surface
= - GMm/R
Total energy = 0
At height 9R ( 8R from the surface )
potential energy
= - G Mm / 9R
Kinetic energy = K
Total energy will be zero according to law of conservation of mechanical energy
so
K - G Mm / 9R = 0
K = G Mm / 9R
The answer is the third one down. New evidence may contradict the old evidence of a certain theory.
Molecules and polyatomic ions are formed by covalent bonds.
Answer:
The relationship between amperage, voltage, and power is that power equals the amperage quantity times the amount of voltage.
