... Halfway home from -- school.
... Twice as far from Earth as -- the moon is.
... The first seat in -- the second row.
... Behind -- the dog's left ear.
... At the bottom of -- the pool.
... On the tip of -- my tongue.
... In the front seat of -- the car.
... I saw you in -- my dream.
... You're always on -- my mind.
The question is trying to get you to realize that to get from a reference point to a certain position, you have to know
How far
and
In what direction.
<u>Answer;</u>
<em>Spring constant </em>
<u>Explanation;</u>
The measure of a spring’s resistance to being compressed or stretched is the <u>spring constant</u>.
- The symbol of spring constant is K, since it is a constant. From the Hooke's law,for a helical spring or any elastic material, the extension force is directly proportional to the extension provided the elastic limit is not exceeded.
- Therefore; the spring constant = Force/extension. That is; K = F/e; where k is the spring constant, F is the extension force and e is the extension.
- Spring constant depicts the resistance of the spring to compressional and stretching forces.
Answer:
![v = 10.89\ m/s](https://tex.z-dn.net/?f=v%20%3D%2010.89%5C%20m%2Fs)
Explanation:
given,
radius of loop = 12.1 m
to find the minimum speed transverse by the rider to not to fall out upside down
centripetal force = ![\dfrac{mv^2}{r}](https://tex.z-dn.net/?f=%5Cdfrac%7Bmv%5E2%7D%7Br%7D)
gravitational force = m g
computing both the equation]
![mg = \dfrac{mv^2}{r}](https://tex.z-dn.net/?f=mg%20%3D%20%5Cdfrac%7Bmv%5E2%7D%7Br%7D)
![v = \sqrt{rg}](https://tex.z-dn.net/?f=v%20%3D%20%5Csqrt%7Brg%7D)
![v = \sqrt{12.1 \times 9.8}](https://tex.z-dn.net/?f=v%20%3D%20%5Csqrt%7B12.1%20%5Ctimes%209.8%7D)
![v = \sqrt{118.58}](https://tex.z-dn.net/?f=v%20%3D%20%5Csqrt%7B118.58%7D)
![v = 10.89\ m/s](https://tex.z-dn.net/?f=v%20%3D%2010.89%5C%20m%2Fs)
