Answer:
Thats a personal question
Explanation:
It asks about you
(illusion is something you think is there but is not)
It depends on what it is closest to but I would say for instance black is 5 points and red is 6 if u land on the line 5.5
Answer:
I like to memorize excerpt from articles to solve and answer questions like these. I hope this can help, it's from study.com: "The relationship between voltage, current, and resistance is described by Ohm's law. This equation, i = v/r, tells us that the current, i, flowing through a circuit is directly proportional to the voltage, v, and inversely proportional to the resistance, r."
To find limits of the amplitude of motion of real vibrating system that is driven at one of its resonant frequencies, Here the damping of vibrations turns the energy of vibration into internal energy.
Explanation:
(a) The given data is as follows.
Length of the rod, L = 0.83 m
Mass of the rod, m = 110 g = 0.11 (as 1 kg = 1000 g)
At the lowest point, angular speed of the rod (
) = 5.71 rad/s
First, we will calculate the rotational inertia of the rod about an axis passing through its fixed end is as follows.
I = 
=
= 
= 0.00631 + 0.415
= 0.42131 
Therefore, kinetic energy of the rod at its lowest point will be calculated as follows.
K = 
= 
= 6.86 J
Hence, kinetic energy of the rod at its lowest point is 6.86 J.
(b) According to the conservation of total mechanical energy of the rod, we have


or, mgh = K = 6.86 J
Therefore, h =
= 
= 0.584 m
Hence, the center of mass rises 0.584 m far above that position.
