In order to make any conclusive diagnosis, I would need to bring Jillian
into my office, and conduct a long, slow, complete, private examination.
Where was I ?
Oh, yes.
As I started to say: Your description of Jillian's behavior is consistent
with a diagnosis of OCD.
ONLY if ur asking for the 3 states of matter it is solid liquid and gas
Answer:
The particle comes to rest before reaching the position x=4m.
Explanation:
When the object is at x=0m, all of its energy is kinetic energy. Using the equation for kinetic energy yields KE=1/2mv^2=(12)(2)(3)^2=9J. Using the given equation for potential energy when the object is at x=4m yields U=4x^2=4(4)^2=64J. Since the system only has 9J of energy, the object comes to rest before reaching x=4m.
Answer: 77 degrees
Explanation:
According to the Law of Reflection, when a ray of light strikes a surface, the angle of this ray (incident ray) with respect to the normal of the surface is equal to the angle that forms the reflected ray with the same normal of the surface.
In other words:
Both the incident ray and the reflected ray and the normal to the surface are in the same plane, in addition, the angle of the incident ray is equal to the angle of the reflected ray.
In this context, if the angle of incidence is 77 degrees, the angle of reflection is 77 degrees, as well.
