Answer:

1) Lithospheric plates move in the asthenosphere due to rising and sinking of materials is 1.

2) The decomposition of radioactive elements causes heat in the interior part of the Earth

3) Heat slowly rises to the mantle and creates convection current.

4). Heat moves to the core

5) The process repeats as cycle.

Explanation:

Mantle convection is the gradual slow creeping of movement of the Earth's mantle which is as a result of convection current which transfer heat from the interior to the surface of the Earth .

The process of mantle convection start with

1. Lithospheric plates move in the asthenosphere due to rising and sinking of materials is and thus form the two component of the mantle.

2) The decomposition of radioactive elements causes heat in the interior part of the Earth. This is as a result of accretion which is associated to sea flooding

3) Heat slowly rises to the mantle and creates convection current.

4). Heat moves to the core, cools down by conduction and convection of heat.

5) The process repeats as cycle.

What is the percentage of the incoming solar radiation from the top of the atmosphere the gets reflected right back out into spa

san4es73 [151]

Answer: We can define the solar constant as a measure of the luminous flux density.

Explanation:

The solar constant or solar constant is the amount of energy radiated at the upper limit of the Earth's atmosphere per unit time perpendicular to the unit surface, at the Earth's mean distance from the sun. Amounts to 1367.7 W / m² ± 6 W / m². The sun's constant includes all kinds of electromagnetic radiation, not just visible light. The average value is 1,368 kW / m2 and changes slightly with solar cycles. The amount of these constant changes over one year and has different benefits.

A 0.5 kg basketball moving 5 m/s to the right collides with a 0.05 kg tennis

Natali5045456 [20]

Answer:

A. 1.4 m/s to the left

Explanation:

To solve this problem we must use the principle of conservation of momentum. Let's define the velocity signs according to the direction, if the velocity is to the right, a positive sign will be introduced into the equation, if the velocity is to the left, a negative sign will be introduced into the equation. Two moments will be analyzed in this equation. The moment before the collision and the moment after the collision. The moment before the collision is taken to the left of the equation and the moment after the collision to the right, so we have:

$M_{before} = M_{after}$

where:

M = momentum [kg*m/s]

M = m*v

where:

m = mass [kg]

v = velocity [m/s]

$(m_{1} *v_{1} )-(m_{2} *v_{2})=(m_{1} *v_{3} )+(m_{2} *v_{4})$

where:

m1 = mass of the basketball = 0.5 [kg]

v1 = velocity of the basketball before the collision = 5 [m/s]

m2 = mass of the tennis ball = 0.05 [kg]

v2 = velocity of the tennis ball before the collision = - 30 [m/s]

v3 = velocity of the basketball after the collision [m/s]

v4 = velocity of the tennis ball after the collision = 34 [m/s]

Now replacing and solving:

(0.5*5) - (0.05*30) = (0.5*v3) + (0.05*34)

1 - (0.05*34) = 0.5*v3

- 0.7 = 0.5*v

v = - 1.4 [m/s]

The negative sign means that the movement is towards left
