Answer:
Reflective
Explanation:
The radiation pressure of the wave that totally absorbed is given by;
and While the radiation pressure of the wave totally reflected is given by;
Now compare the two-equation you can clearly see that the pressure due to reflection is larger than absorption therefore the sail should be reflective.
It increases, because the centripetal acceleration is inversely proportional to the radius of the curvature.
Hopr it helps :)
The ice is going from one stage to another making it a physical change we it melts it goes from a solid to a liquid.
As the angle the plane makes with the horizontal is increased, the magnitude of the force of static friction between the block and the plane (2) increases
<h3>Static frictional force</h3>
Since the static frictional force between the block and the plane is given by F = μN where
- μ = coefficient of static friction and
- N = normal force on plane = component of weight of block perpendicular to the plane = Wcosθ where
- W = weight of block and
- θ = angle of inclined plane
Now, F = μN
F = μWcosθ
Since μ and W are constant, we see that
F ∝ cosθ and cosθ ∝ θ
So, F ∝ θ
Since the static frictional force is directly proportional to the angle the plane makes with the horizontal, when the angle the plane makes with the horizontal is increased, the static friction between the block and the plane increases.
So, As the angle the plane makes with the horizontal is increased, the magnitude of the force of static friction between the block and the plane (2) increases
