In a collision an object experiences impulses, this impulse can be determined by the product of net force exerted upon it in the specific course of time.
<u>Explanation:</u>
An object experiences impulse due to the force exerted upon it in a particular time period.
i.e.
Where,
F - Force acted upon the object
- time interval for which the force act
According to the definition of Impulse, it is the integral of force (F) that acts upon any object over a time interval ∆t. It produces an equivalent change in the momentum and that too in the same direction as of the applied force (F).
Therefore, in order to find the impulse on an object, we have to find the force acted on it in a specific time interval.
Answer:
Explanation:
We can solve the problem by using Snell's law:
where
n1 = 1.33 is the index of refraction of the first medium (water)
n2 = 1.00 is the index of refraction of the second medium (air)
is the angle of incidence of the wave in water
is the angle of refraction of the wave in air
Solving for the angle of refraction,
