EPE= 0.5 * spring constant * (extension)^2
Spring constant=EPE/0.5*extension^2
5J/0.5*0.5^2
=40N/m
Answer:
is only producing an electric field in the surrounding space
Explanation:
Answer:
<h3>Law of reflection</h3>
Explanation:
According to the laws of reflection,
- Incident ray, reflected ray and normal lie on the same plane.
- Angle of reflection and angle of incidence are always equal.
→ Angle of reflection : Angle of which light rays reflect off surface.
→ Angle of incidence : Angle at which light rays strikes the surface.
Kinetic energy is a form of energy that an object or particle has by reaction of its motion.
Answer:
i. Geodynamo
ii. Gravitational energy conversion
Explanation:
The outer core of the Earth is believed to be in molten form, consisting of mainly iron and nickel. The reaction (mixture) between these components or elements generates conventional currents which is maintained by the gravitational energy produced in the process. Thus, magnetic fields are generated continuously due to the continuous flow of electric current during the processes.
