The philosophy is
simple that no one can start the journey towards being a Muslim unless he
professes the basic principles mentioned in the "Declaration of
Faith", which is "<span>“There is none worthy of
worship but Allah and Muhammad is His Messenger”.
The declaration consists of the two most fundamental elements of Islamic ideology:
1) Unity of Allah: Declaring that there is only One God and none else is mandatory
to be a Muslim.
2) Faith in the prophet hood of Muhammad, the messenger of Islam.</span>
A) GPS monitoring of plate speeds and movements.
Explanation:
The most recent evidence supporting the theory of plate tectonics would be GPS monitoring of plate speeds and movements.
A GPS is a Global Positioning System made up of series of components.
- Plate tectonics theory is the movement of the earth's lithosphere relative to one another.
- The recent advances uses a GPS system to monitor real-time movement of the plates.
- The GPS system is made up of a system of satellite in space that communicates real-times locations to sensors on the earth surface.
- From the sensors, observatory stations can know and duly observe how plates are moving.

Answer:
The speed of the block is 8.2 m/s
Explanation:
Given;
mass of block, m = 2.1 kg
height above the top of the spring, h = 5.5 m
First, we determine the spring constant based on the principle of conservation of potential energy
¹/₂Kx² = mg(h +x)
¹/₂K(0.25)² = 2.1 x 9.8(5.5 +0.25)
0.03125K = 118.335
K = 118.335 / 0.03125
K = 3786.72 N/m
Total energy stored in the block at rest is only potential energy given as:
E = U = mgh
U = 2.1 x 9.8 x 5.5 = 113.19 J
Work done in compressing the spring to 15.0 cm:
W = ¹/₂Kx² = ¹/₂ (3786.72)(0.15)² = 42.6 J
This is equal to elastic potential energy stored in the spring,
Then, kinetic energy of the spring is given as:
K.E = E - W
K.E = 113.19 J - 42.6 J
K.E = 70.59 J
To determine the speed of the block due to this energy:
KE = ¹/₂mv²
70.59 = ¹/₂ x 2.1 x v²
70.59 = 1.05v²
v² = 70.59 / 1.05
v² = 67.229
v = √67.229
v = 8.2 m/s
The answer is :78 I think
