Answer:
The position of the spring in terms of g, m & k is ![x = \frac{m g}{k}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7Bm%20g%7D%7Bk%7D)
Explanation:
Stiffness of the spring = k
Mass = m
When a mass m is attached with the spring then spring stretched. in that case the force exerted on the spring is equal to weight of the mass attached.
⇒ Force exerted on the spring F = k x
⇒ m g = k x
⇒ ![x = \frac{m g}{k}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7Bm%20g%7D%7Bk%7D)
This is the position of the spring in terms of g, m & k.
Answer:
Positive.
Explanation:
As a consequence of the photoelectric effect, electrons that will get hit by sufficiently energetic photons will abandon the metal surfaces exposed to bright sunlight. This decreases the negative charge of the surface, thus causing it to develop a positive net charge.
Rubber,Plastic,I think thats it but everyone that can float has a high buoyancy
