The layers that make up the upper mantle are the following.
- The lithosphere and the asthenosphere.
- The lithosphere and the asthenosphere are the layers that make up the upper mantle.
- The rocky outer part of the Earth is called the lithosphere.
- It is very rigid, solid, and it is not as hot as the other parts.
- According to scientists, its thickness is about 90 to 100 kilometers from the surface of the earth.
- The layer of the Earth that moves the lithospheric plates is called the asthenosphere.
- Lithospheric plates are 60 miles long on average and are composed of continental crust.
We conclude that the lithosphere and the asthenosphere are the layers that make up the upper mantle. The new lithosphere is being created at oceanic ridges due to plate tectonics. Yes, planet Earth is getting larger constantly.

Without a picture of the situation, we don't know the relationship
between angle-G, g, k, and 'h'. We don't even know for sure
whether 'h' is on the same planet as the other things. No answer
is possible without seeing the picture.
Answer:
The answer is below
Explanation:
a) The vertical displacement = Δy = 21.5 m - 1.5 m = 20 m
The horizontal displacement = Δx = 69 m wide
Using the formula:
Also:
b)The car is moving at a constant speed in the horizontal direction, hence the initial velocity = final velocity
Answer:
Part a)
charge on each sphere is -1.95 micro coulomb
Part b)
For first sphere
excess charge
For second sphere
excess charge
For third sphere
absent charge
For third sphere
absent charge
Explanation:
Part a)
Since all the spheres are of identical size so the total charge of the sphere will divide equally on them
So we have
So charge on each sphere is -1.95 micro coulomb
Part b)
For first sphere
initial charge = 2.2 micro coulomb
final charge = -1.95 micro coulomb
excess charge = -1.95 - 2.2 = -4.15 micro coulomb
Q = Ne
For second sphere
initial charge = 4.2 micro coulomb
final charge = -1.95 micro coulomb
excess charge = -1.95 - 4.2 = -6.15 micro coulomb
Q = Ne
For third sphere
initial charge = -7.4 micro coulomb
final charge = -1.95 micro coulomb
absent charge = -1.95 + 7.4 = 5.45 micro coulomb
Q = Ne
For third sphere
initial charge = -6.8 micro coulomb
final charge = -1.95 micro coulomb
absent charge = -1.95 + 6.8 = 4.85 micro coulomb
Q = Ne
Answer:
a: 19.6 meters b: 9.8meters per second
Explanation:
speed and object falls is 9.8 meters per second. 9.8 meter times 2 is 19.8 meters.
