Answer:
- Earthquakes occurs due to the sudden shaking of the earth, produced due to the collision of plates.
- Continental drift is the theory that describes how continents moves from one place to another with respect to a fixed point. Plate tectonic movement is responsible for this drift.
- When two continental plate collides, sandwich pattern forms, which leads to the mountain building processes. For example, the Himalaya.
- When collision takes place between an oceanic plate and a continental plate, the oceanic plate being more denser gets subducted below the comparatively less dense continental plate, producing volcanoes, where extensive volcanic eruptions takes place.
- When two oceanic plate collides, the denser oceanic plate gets subducted beneath the less denser one, thereby creates an island arc or chain of island. For example, the Hawaiian island chain.
All the above phenomenon are directly related to the plate tectonic movement.

Answer:
Explanation:
The force experimented by a charge <em>q </em>in a uniform electric field <em>E</em><em> </em>is <em>F=qE</em>.
Newton's 2nd Law tells us that the relation between acceleration <em>a</em> a mass <em>m </em>experiments when a force <em>F </em>is applied to it is <em>F=ma</em>.
Combining these equations we have <em>am=qE</em>, and since we want the acceleration of the speck of dust, we substitute our values:
The cloud chamber, the Geiger counter, and a piece of
photographic film can all reveal the presence of radioactivity.
Batteries don't.
Unit for x - the change in the spring length:
x = [ m ]
PE s = 1/2 k x²
[ kg m² / s² ] = 1/2 k * [ m² ] /: m²
k = [ kg / s² ]
Answer: The unit for spring constant k is kg/ s²
