Answer
Nature of the surfaces.
Explanation
Friction is the the force that opposes motion between two surfaces that are in relative motion. If two objects are in contact, one of it or both must be in motion for friction to exist.
Friction is affected by a number of factors.
One is the weight of the object. The more the weight of the object the higher the friction between it and the surface.
The other factor is the nature of the surfaces. Rough surfaces contribute to high friction while smooth surfaces reduces the friction between surfaces.
its B 0.225kPa using the formula p=f/A then change the pascals into kpa
Answer:
Hey, I'm not sure I understand exactly what your assignment is but hopefully this helps . . .
put the other end against the side of the bubls base to light up the light bulb.
This will act as the bulbs conductor, lighting up bc you are making a complete electrical circuit between positive and negative terminals of the battery.
Ok hopefully this helps you out
Answer:
0.05 rad/s
Explanation:
7.8 km = 7800 m
For the residents inside the space cylinder to experience the same gravitation acceleration g = 9.81m/s2 on Earth, the centripetal acceleration must be the same as g
But centripetal acceleration is product of angular velocity squared and radius of rotation r
