Answer:
Part a)
When there is no friction then acceleration is
Part b)
if there is friction force along the inclined then acceleration is
Explanation:
Part a)
As we know that the skier is on inclined plane
So here if there is no friction then net force along the inclined plane is given as
now acceleration of the skier is given as
Part b)
if there is friction force along the inclined then net force along the inclined plane is given as
now acceleration of the skier is given as
Answer:
sin 40 = n sin 26 snell's law for incoming ray in air
n = sin 40 / sin 26 = 1.47

<u>Answer
</u>
4.The objects have the same acceleration
<u>Explanation
</u>
Acceleration due to gravity is the acceleration acquired by an object when falling freely.
Under normal conditions, different objects has different accelerations depending on their mass and surface area. This is brought about by the air resistance they experience as they fall.
The case is difference when they the experiment is carried out in a controlled condition. That is in vacuum. I this case the acceleration of the objects is the same.
