Answer:
The geological features that is not created by the movement of the Earth's plates is Canyons.
To get the velocity you need to know the displacement and the time.
I hope that helps!
Answer:
The answer is below
Explanation:
a) The change in energy is the difference between the final energy and the initial energy.
ΔE (energy change) = Ef (final energy) - Ei (initial energy)

The negative sign shows that energy is lost to the environment. Hence 0.334 J is lost to the environment.
b) According to the law of conservation of energy, energy cannot be created or destroyed but transformed from one form to another.
The oscillating object loses energy due to wind resistance, friction between the spring and the object. Given that the air is frictionless, hence the energy loss is due to friction which is converted to heat.
The sun’s light and other forms of electromagnetic energy reach the earth by radiation. The mass of the sun acts on the earth (and other planets) by gravity which steers the earth in an almost circular orbit round the central sun.
Answer:
= 1.6
Explanation:
= Angle of incidence = 65.9°
= Angle of refraction = 34.8°
= Index of refraction of air = 1
= Index of refraction of glass = ?
Using Snell's law
Sin
=

(1) Sin65.9 =
Sin34.8
= 1.6
