1)due to it's position in the gravitational field
2)due to it's motion
51.448 g is the required answer!
There are two equal forces of gravity between the Earth and the Moon.
One force pulls the Moon toward the Earth.
The other force pulls the Earth toward the Moon.
If only this gravity suddenly switched off, then the moon would
continue to orbit the Sun, very much as it does now.
If ALL gravity suddenly switched off, then . . .
-- the Moon would stop orbiting the Earth and would sail away, in
a straight line and at the speed it had when gravity disappeared;
-- the Earth would stop orbiting the Sun and would sail away, in
a straight line and at the speed it had when gravity disappeared;
-- all the gases surrounding the Earth ... which we call "air" ... would
start drifting away, and expanding into a giant cloud of gas, and stop
being an atmosphere;
-- the Sun would completely fall apart, expand into a giant cloud of gas,
and stop being a star.
Answer:
1.34 × 10⁻⁵
Explanation:
Let's consider the acid dissociation of propanoic acid.
CH₃CH₂COOH(aq) + H₂O(l) ⇄ CH₃CH₂COO⁻(aq) + H₃O⁺(aq)
We can find the acid dissociation constant (Ka) using an ICE chart.
CH₃CH₂COOH(aq) + H₂O(l) ⇄ CH₃CH₂COO⁻(aq) + H₃O⁺(aq)
I 0.65 0 0
C -x +x +x
E 0.65 - x x x
We know that [CH₃CH₂COO⁻] = [H₃O⁺] = x = 2.95 × 10⁻³ M
[CH₃CH₂COOH] = 0.65 - 2.95 × 10⁻³ = 0.64705 M
Ka = [CH₃CH₂COO⁻].[H₃O⁺]/[CH₃CH₂COOH]
Ka = (2.95 × 10⁻³)²/0.64705
Ka = 1.34 × 10⁻⁵
