The lists that arranges the Earth's compositional layers in order of increasing density is CRUST, MANTLE AND THEN CORE. The core is considered as the most dense and the lithosphere, which makes the outermost core, is considered as having the least density. Hope that this answer helps.

A person with a mass of 15kg is walking uphill at a velocity of2m/s. What is the walker's momentum?
Nadusha1986 [10]

Answer:

30 kgm/s

Explanation:

The momentum of a body is given by the product of mass and  its velocity.

∴ momentum = mv

                        = 15 × 2

                        = 30 kgm/s

20.Two balls are in motion. A 2-kg ball moving at 4m/s and a 4-kg ball moving at 2m/s, which one has greater kinetic energy? a.
bekas [8.4K]

Answer:

A

Explanation:

Given that two balls are in motion. A 2-kg ball moving at 4m/s and a 4-kg ball moving at 2m/s, which one has greater kinetic energy? a. 2 kg ball moving at 4 m/s c. Both balls have the same KE b. 4 kg ball moving at 2 m/s d. Cannot be determined

The formula for kinetic energy is :

K.E = 1/2mv^2

A 2-kg ball moving at 4m/s will have kinetic energy of 1/2 × 2 × 4^2

K.E = 16J

and a 4-kg ball moving at 2m/s will have kinetic energy of 1/2 × 4 × 2^2

K.E = 2 × 4

K.E = 8J

which one has greater kinetic energy? Definitely it is a 2 kg ball moving at 4 m/s. Since 16J is greater than 8J. The correct answer is A.

Can someone please answer this science question please?
olga nikolaevna [1]
Volcanoes: Most volcanoes are formed by the movement of tectonic plates<span> on the surface of the earth. These plates basically float on mantle. Sometimes these plates will sink into the mantle. The rock becomes so hot it melts. Gradually, the molten rock (the melted rock) will then make it's way back up. When it surfaces it, we call it "lava". As lava layers, it slowly forms a volcano. 

Valleys: Basically formed by a river valley. The stream shapes the Earth's crust over time into a funnel-like v-shape or u-shape (depending on the flow of the stream).

Mountains: When plates collide and through pressure start building up into a cone shape.</span>
