The answer is A. Opposites attract, hence the attraction during friction. Balloons and hair would be a great example.
Answer:
-0.314 rad/s²
197.39 m/s²
197.49 m/s² and 1.822° counterclockwise.
Explanation:
= Final angular velocity
= Initial angular velocity
= Angular acceleration
= Angle of rotation
t = Time taken
R = Radius = 20 m
Angular acceleration of the turbine is -0.314 rad/s²
Centripetal acceleration
The centripetal acceleration of the tip is 197.39 m/s²
Tangential acceleration
Acceleration
Magnitude and direction of the total linear acceleration of the tip of the blades is 197.49 m/s² and 1.822° counterclockwise.
Answer:
D) stays the same, decreases
Explanation:
When one travels away from the earth surface, one's mass remains the same but the weight decreases as the gravitation pull decreases.
Beta particles ARE electrons.
Also, in one of the great coincidences of Physics, electrons ARE beta particles.
Conductive deafness refers to a malfunction of the middle ear. Those 3 ossicles (malleus, incus, stapes) are responsible for converting the sound wave and conducting it to the inner ear.
