Before comparing and contrasting these layers of Earth, we first define what lithosphere and asthenosphere are.
Lithosphere primarily consists of the outermost layers of the Earth, which are the crust and the uppermost portion of the mantle. Simply, the ground you stepped on is part of earth's lithosphere. On the other hand, asthenosphere comprises of hot and partially molten rock just located at the upper portion of the mantle but just below the lithosphere. Both have similarities and differences, which are as follows:
SIMILARITIES:
- Both are the passageways of earthquakes P-waves (Primary waves) just before it reaches the earth's surface.
- Both are made of the same material (Silicon oxide rocks, which are rich in iron and magnesium)
DIFFERENCES:
- Rocks in lithosphere can bend (it deforms, resulting in fault formations), however, rocks in the asthenosphere, not only bend but also flow (plastic in nature).
- Lithosphere has relatively low temperatures compared to asthenosphere.
- Due to its depth, pressure against rocks in asthenosphere is comparatively higher compared to lithosphere.
Answer: Option (A) is the correct answer.
Explanation:
When more and more energy is provided to a gas then its atoms move more rapidly.
This rapid and continuous movement converts the gas into hot ionized ions which have positively charged ions and negatively charged electrons.
Therefore, we can conclude that as the atoms move faster, the gas can change into a plasma.
Answer
given,
Pressure on the top wing = 265 m/s
speed of underneath wings = 234 m/s
mass of the airplane = 7.2 × 10³ kg
density of air = 1.29 kg/m³
using Bernoulli's equation
Applying newtons second law
2 Δ P x A - mg = 0
A = 3.53 m²
Once the atomic number of an atom is known, the number of electrons can be deduced depending on if the atom is an ion or a neutral one.
<h3>Atomic number</h3>
The atomic number of an atom is the number of protons in the nucleus of the atom.
For atoms that are neutral, that is, no net charges, the number of protons is always equal to the number of electrons. In other words, the positive charges always balance the negative charges in neutral atoms.
Thus, if the atomic number of a neutral atom is 6, for example, the proton number will also be 6. Since the proton must balance the electron, the number of electrons will also be 6.

Newton's second law of motion can be formally stated as follows: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
