. A force of 16 N acts on a mass of 11 kg at an angle of 18à above the horizontal. Given the particle is on the point of slipping, what is the coefficient of friction between the particle and the plane?

In a laboratory, nakisha mixes sodium hydroxide solution with an indicator called phenolphthalein. when combined, they create a pink solution. nakisha wonders if mixing other solutions with phenolphthalein will also create this pink color. how could she use the scientific inquiry process to explore it further?

Explain earth's motion, using the terms "precession" and "rotation" in your answer.

The coefficient of friction is a number that represents the resistance to sliding between two in contact with one another.
