Option D. The mechanical layer of Earth that has the most active convection currents is Asthenosphere.
<h3>What is Asthenosphere?</h3>
The asthenosphere is the mechanically weak and ductile region of the upper mantle of Earth.
The asthenosphere, zone of Earth's mantle lying beneath the lithosphere and believed to be much hotter and more fluid than the lithosphere. It is the most active layer for convection current.
Thus, the mechanical layer of Earth that has the most active convection
currents is Asthenosphere.

The incandescent lamp will glow quite brightly in the eyes of the creature because emits less visible light and more infrared light.
<h3>What is infrared light?</h3>
The infrared light is a part of the electromagnetic spectrum that is emitted by a hot object.
As such, the incandescent lamp will glow quite brightly in the eyes of the creature because emits less visible light and more infrared light. The florescent light which does not produce inferred rays will not be visible at all.

Answer:
Normal Force is usually perpendicular to the movement and static friction usually means that there is no movement.
Explanation:
The work donde by any force on an object is equal to the displacement of the object multiplied by the component of the force that is in the direction of the displacement.
Normal force is usually perpendicular to the movement, so there is no component in the direction of the displacement. This is why it is zero in most circumstances.
<em>Static</em> friction on the other hand, usually means that there is no movement at all (it's static). It means that there is no displacement between the object and ground (in most cases). If there is no displacement, there is no work.
Answer:
Explanation:
Given:
the displacement as the function of time:
here time is in seconds and the displacement in meters.
Now we differentiate this eq. of displacement to get the equation of velocity:
According to given the velocity is at some time:
& is the only time for (t>=0) instances when the particle will have a velocity of but in the opposite direction.
Answer:
Radiation
Explanation:
Radiation is the type of heat transfer through the electromagnetic waves. Transfer of heat by radiation can occur in space/vacuum as in between the sun and the earth
On the other hand:
Conduction is the transfer of heat through touching on objects while convection is the transfer of heat as a result of moving currents in liquids or gases.
Hope this helps :)
