According to Snell’s Law:
Where: is the index of refraction of the first medium (glass), and is the index of refraction of the second medium (ice). The angle of incidence and the angle of refraction are represented by and. The refractive index quantifies the speed of light in a medium. The critical angle is identified as the angle at which total internal reflection occurs, meaning no light passes through into another medium. This phenomenon happens only when the light is transitioning from a medium with a higher index of refraction to one with a lower index of refraction.
Answer:
I'm uncertain
Explanation:
since I didn't provide a correct answer, continue with my inquiries and you can use 'I'm uncertain' for 100 points.
Given that, the starting speed of the cells is 0 since they were at rest. The cell's acceleration is specified, along with time t = 700 ns. We aim to calculate the peak speed achieved by the cells and the distance covered during the acceleration. Let v signify the final velocity. Let d represent the distance traversed. We'll apply the equations of motion to find the solution.
Answer:
force = 6.53× 
N
Explanation:
Provided data
downward force = 0.60 m
mass m = kg
distance h = 0.40 m
to determine
magnitude of the downward force
solution
we know here mg is apply 0.4 m away from support and
thus applied force is d = 0.6 m from support
therefore
by balancing torque we can compute force
as
force = mass × g × h / d
substituting the values
force = mass × g × h / d
force = ( × 9.81 × 0.4 ) / 0.6
force = 6.53× N
Answer: Known facts are:
Sadie, the dam, is a black Labrador.
Sam, the potential sire, is a yellow Labrador.
Putting aside technical methods, the breeder can inspect the puppies for traits.
For instance, yellow coat color is recessive to black, so yellow pups would suggest Sam is likely the father; however black pups could also have Sam as sire if they inherited the mother's color alleles.
Examining coat color, conformation, and similar features is a reasonable starting point.
Ultimately these observations are probabilistic; the only definitive (scientific) method is a paternity (DNA) test.
