I believe that it is d correct me if wrong because the higher the temperature the more active the molecules are gonna be, but the graph does not explicitly state that, so you can say the answer is d (if not the answer is c) (sorry if wrong)
Answer:
a shiny smooth leaf
Explanation:
A shiny smooth leaf will cause specular reflection. Other choices will cause diffused reflection from the surface.
A specular reflection is similar to how a mirror or smooth surface reflects. The incident light is given off as a single ordered reflection from the surface of a body.
For this to occur, the surface incident must be smooth and without rough patterns on it.
A path way with rough rocks, small patch of soil and rough logs will give off diffused reflection

Answer:
Part a)
Part b)
Explanation:
Part a)
As we know that the diameter of the planet is given as
now the radius of the planet is given as
now we know that the acceleration due to gravity of the planet is given by the equation
here we know that
now from above equation we have
now we have
Part b)
Now by kepler's law we know that
time period of revolution of planet about the star is given as
so we have
now we have
mula of time period
Now we have
