Explain briefly how the following phenomena happen on Earth, relating your answers to the theory of plate tectonics
Elenna [48]

Answer:

  1. Earthquakes occurs due to the sudden shaking of the earth, produced due to the collision of plates.
  2. 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.
  3. When two continental plate collides, sandwich pattern forms, which leads to the mountain building processes. For example, the Himalaya.
  4. 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.
  1. 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.

Suppose a=3i-2j+k b=-i-4j+3k and c is avector lying along positive x axis with the property that a(b+c)=0 then find c?
il63 [147K]

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).

At a certain depth in the ocean. the absolute pressure is p. If you 90 to twice that depth (treating the water as incompressible
KatRina [158]

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

A charged ball of mass 10g and charge 2 C is placed at rest in a field of field strength 5NC as shown.
Natali [406]

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
