Answer:
The angle between the red and blue light inside the glass is 1.9°.
Explanation:
Given that,
Refractive index
For blue = 1.64
For red = 1.54
Incident angle = 48°
We need to calculate the angle between the red and blue light inside the glass
Using Snell's law
For blue ray,
For red ray,
We need to calculate the angle between the red and blue
Put the value into the formula
Hence, The angle between the red and blue light inside the glass is 1.9°.
Answer:
1,170
Explanation:
Kinetic energy=1/2×m×velocity squared
Answer:
Part a)
Part b)
Part c)
Part 4)
angular acceleration will be ZERO
Part 5)
Explanation:
Part a)
Moment of inertia of the system about left end of the rod is given as
So we have
Part b)
If force is applied to the mid point of the rod
so the torque on the rod is given as
now angular acceleration is given as
Part c)
position of center of mass of rod and sphere is given from the center of the sphere as
so moment of inertia about this position is given as
so we have
Part 4)
If force is applied parallel to the length of rod
then we have
so angular acceleration will be ZERO
Part 5)
moment of inertia about right edge of the sphere is given as
so we have
Its 200 west but 100 north, if it north was 200, the answer would be C, but being the case of 200, 100 on two different answers that has north and west wouldn't be right
