More absorption of solar radiation occurs with a higher angle of the sun.
Option A is correct
Around 30% of the incoming radiation is reflected back to space and does not heat the surface, leaving the other 70% to be absorbed by the atmosphere and the Earth's surface. Because it is colder than the Sun, the Earth radiates energy at wavelengths that are far longer.
This radiation is the radiation that eventually makes it to the Earth's surface after repeated route changes, such as those caused by atmospheric gases. solar radiation reflection. The albedo effect is a phenomena wherein a portion of solar radiation is reflected by the earth's surface itself.

How is torque calculated?
As the cross product of force and lever arm length, torque is defined in the first formula for torque as the moment of force (Torque T=r x F).
The time rate change of angular momentum is how torque is expressed in the second torque formula. T = ΔL/ΔTDepending on the subject of study, it is also known as the moment, moment of force, rotating force, or turning effect. Archimedes' studies on the use of levers are where the idea first emerged. A torque can be thought of as a twist to an item about a particular axis, much as a linear force is a push or a pull.The force that can cause an object to rotate along an axis is measured as torque. In linear kinematics, force is what drives an object's acceleration. Similar to this, an angular acceleration is brought on by torque. As a result, torque can be thought of as the rotational counterpart to force.To know more about torque

what is the motion of the negative electrons and positive atomic nuclei caused by the external field? view available hint(s)for part b what is the motion of the negative electrons and positive atomic nuclei caused by the external field? both electrons and nuclei move to the right. the nuclei move to the right and the electrons move to the left through equal distances. the electrons move to the left and the nuclei are almost stationary. the electrons are almost stationary and the nuclei move to the right.
Electrons and nuclei both migrate to the right. In an electric field, nuclei travel to the right and electrons move to the left by equal lengths.
Negative electrons migrate to the left. When an external field is applied, the positively charged current travels to the right in the opposite direction.
The positive atomic nuclei are nearly stationary.
The electric field always points in the direction that a positive test charge would be pushed or pulled if placed in the area surrounding the source charge. Electric field may be represented by a vector arrow since it is a vector quantity.

a boat develops a leak and, after its passengers are rescued, eventually sinks to the bottom of a lake. when the boat is at the bottom, what is the force of the lake bottom on the boat? (a) greater than the weight of the boat (b) equal to the weight of the boat (c) less than the weight of the boat (d) equal to the weight of the
When the boat is at the bottom of the lake, the force of the lake bottom on the boat is less than the weight of the boat. The correct answer is c.
The force of the lake bottom on the boat would be less than the weight of the boat. This is because the buoyant force, which is equal to the weight of the displaced water, would be acting in the opposite direction and would partially cancel out the force of gravity acting on the boat. The net force acting on the boat would be the difference between the weight of the boat and the buoyant force, which would be less than the weight of the boat.
