Answer:
The core: this structure of the terrestrial world is made up of sulphur, iron, silicon and it is found at the centre of the terrestrial world.
The mantle: this structure of the terrestrial world is located between the outer core and the crust and consist of mainly silicate rock.
The crust: this is the structure of the terrestrial world that makes up the outermost layer. It consist of granite and basalt.
Differentiation: this is the process by which gravity separates materials according to density, with high-density materials sinking and low-density materials rising.
Lithosphere: this is made up of the hard and rigid outer layer of the terrestrial planet and it's located between the crust and the outermost mantel.
The five terrestrial worlds includes Mercury, Venus, Earth, the Moon, and Mars. The largest which includes the Venus and Earth has the thinnest lithosphere while the smallest ( mercury and moon) have the thickest lithosphere.
Answer:
To burst the second barrel, the height of water should also be equal to 20 feet
Explanation:
Diameter of the pipe on the first barrel = 1 ft
Diameter of the pipe on the second barrel = 1/2 inch
The pressure of water in the pipes needed to burst the barrel, 
To burst the barrel having the larger pipe, water was filled to a height of 20 ft
Note that the pressure of water in the pipes as given by the equation above does not depend on the diameters of the pipe. It only depends on the height, density and acceleration due to gravity. Since the density of water and the acceleration due to gravity are constant, for the second pipe to also attain the same pressure as the first pipe needed to burst the barrel, the height of water in the two pipes must be equal
The displacement is the distance from the beginning point to the ending point. The time was just to throw you off. If he walks 30m due west, and then 5m due east, his displacement would be 30-5=25m to the west.
Answer:
the answer is 49ft/s
Explanation:
if you look for the equations of uniformly accelerated motion you find the following
Vo=Vf-AT
Where
Vo=initial speed
Vf=final speed
A=aceleration
T=time
you replace and it's all
Vo=55-2x3
Vo=49ft/s
