Answer:
3600km
Explanation:
gravitational constant is the gravitational attraction between any two things
G = gravitational constant = 6.67 × 10⁻¹¹ Nm²/kg²
g = acceleration due to gravity = 4 m/s²
M = mass of the earth = 6 × 10²⁴
r = radius of Earth + height of meteor
Since F = mg and F = GMm/r², mg = GMm/r²
g = GM/r²
r² = GM/g
r = √(GM/g)
r = √((6.67 × 10⁻¹¹ Nm²/kg²) × (6 × 10²⁴ kg))/(4 m/s²)) =
1 × 10⁷ m = 1 × 10⁴ km
To calculate the height of the meteor above the earth,
subtract the radius of the earth from the calculated radius.
height of meteor = 1 × 10⁴ km - 6 × 10³ km = 4 × 10³ km

Answer:
Cations (positively-charged ions) and anions (negatively-charged ions) are formed when a metal loses electrons, and a nonmetal gains those electrons. The electrostatic attraction between the positives and negatives brings the particles together and creates an ionic compound, such as sodium chloride.
Explanation:
The cabinet is being pulled with 200N and is being rested by a force equal to 200N. That is why it is not being moved.
<span>Although the force of static friction can equal Fk=µs*F=m*g*µs=(30kg)*(9.8m/s^2)*(0.80)=235 N. It is not resisting the 200N force with 235N. Imagine if you pushed something with 200N and it pushed you back with 235N, especially a cabinet. You would think that the cabinet was alive.</span>
