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.
The smallest particle of the atom is called an Electron. Electrons are negatively charged and surround the protons and neutrons.
The value of the c will be (0 i+0 j+0 k). c is a vector that is along the positive x-axis and has the condition a(b+c)=0.
<h3>What is a vector?</h3>
A vector is a quantity or phenomena with magnitude and direction that are independent of one another. The phrase also refers to a quantity's mathematical or geometrical representation.
Given ;
a=3i-2j+k
b=-i-4j+3k
Given property:
a(b+c)=0
-i-4j+3k ((-i-4j+3k)+c)=0
(3+8+3)(-i-4j+3k)c=0
14(-i-4j+3k)c=0
c=0 i+0 j+0 k
Hence, the value of the c will be (0 i+0 j+0 k).

Answer:
correct option is B
the absolute pressure will be less than 2p
Explanation:
given data
absolute pressure = p
depth = twice
to find out
what is correct option
solution
we know here that p absolute pressure so we consider atmospheric pressure p1
so we can say at some depth h pressure will be
pressure p = p1 + ρ g h
so if depth is double
pressure will be
2p = 2p1 +2 (ρ g h )
so
2p - p1 = p1 + 2 (ρ g h )
so correct option is B
the absolute pressure will be less than 2p
Answer:
1000 m/s
Explanation:
Given that
Mass of the ball, m = 10 g = 0.01 kg
Charge of the ball, q = 2 C
Field strength of the field, E = 5 N/C
Acceleration of the ball, a = ? m/s²
We know the the equation holds,
F = qE, on substituting, we have
F = 2 C * 5 N/C
F = 10 N
Also, we know that
F = ma, and as such,
a = F / m, on substituting we have
a = 10 N / 0.01 kg
a = 1000 m/s²
Therefore, the acceleration of the ball is 1000 m/s²
