I think its c because a pivot joint would be circular movement in only one manner and that matches the turning of a door knob. a hinge joint does not swivel like a chair or move like a shower head, and a cabinet door, in my opinion would be like a hinge joint
Can you provide more of the question so I can answer it?
Given data:
● Angular velocity of the turntable ω = 33 rev/min
Therefore,
ω = 33 rev/min
ω = 33rev/min × 2π rad/rev × 1 min/60 sec = 3.45 rad/s
● The distance of the watermelon seed from the axis of rotation r = 7.8 cm = 0.078 m
● μs = the coefficient of static friction
Section a:
The seed is undergoes circular motion and it is been effected by centripetal acceleration.
ac = rω^2
ac = 0.078 × 3.45^2
ac = 0.9284 m/s^2
Therefore,
the centripetal acceleration of the seed is 9.274 m/s^2
Section b:
If the seed is observed not to slip at the course of the circular motion, then the supplied frictional force given by the seed and surface of turntable would at least be equivalent to the centripetal force working on the seed.
Centripetal Force = Frictional Force
mrω^2 = μsmg
μs = rω^2 /g
μs = 0.078 × 3.45^2
------------
9.81
μs = 0.09464
Thus,
the coefficient of static friction is 0.09464.
Answer:
echinoderm I'm pretty sure but I'm not 100% so if I get it incorrect I'm sorry
Answer:
At the time in our history when there were slave owners, it was part of our culture to own slaves to help with the labor on farms. It did not make slave owners INHUMAN. It was part of the culture of the times. Maybe not the best part of our culture but was accepted by millions of people and I dont think there were millions of people that were INHUMAN. It was part of our history and we learned from the mistakes of the past. As our culture and society change so do the beliefs and acceptable societal norms. Sometimes for the better sometimes for the worst. Hopefully, most of the time for the better.
