The variable on the y-axis should be the running speed of hamsters since it is the dependent variable.
<h3>What is the dependent variable?</h3>
The dependent variable is the variable whose value fluctuates depending on other variables in an experiment.
In this case, the running speed is the dependent variable because it depends on the weight of the hamster.
The dependent variable is generally graphed on the Y axes, whereas the independent variable is graphed on the X-axes.
In conclusion, the variable on the y-axis should be the running speed of hamsters since it is the dependent variable.

Answer:
Option (B) is true
Explanation:
refractive index of water = n1
refractive index of air = na = 1
refractive index of oil = n2
When the ray goes from water to air
Use Snell's law
Let the angle of incidence is i
n1 Sin i = na x Sin r
For total internal reflection, r = 90°
n1 x Sin i = 1 x Sin 90
Sin i = 1 / n1 .... (1)
For water oil interface
angle of incidence is i and let the angle of refraction is r.
n1 x Sin i = n2 x Sin r
n1 x / 1 n1 = n2 Sin r (from equation (1)
Sinr = 1/n2
Answer:
Biodiversity decline continues due to a rapidly expanding human population. Habitat is damaged in order to meet growing needs for agriculture, urban development, water and materials. Fish, wildlife and plants are overharvested, despite mounting evidence that many harvesting practices are unsustainable.
Tectonic plates under the ground ,either go on top of each other or crash.
The unpolarized light becomes less intense. When unpolarized light is run through a polarizer, its intensity is diminished by a factor of ½.
<h3>Unpolarized light:</h3>
Unpolarized light is diminished by a factor of ½ when it travels through a polarizer. Cos 2θ averages out across all angles to be ½ in size. I transmitted = I₀ and ½ I₀ at all angles The unpolarized light's intensity decreases to zero.
The light-producing atoms on the heated filament's surface behave independently of one another. Each of these emissions can be roughly represented as a brief "wave train" lasting between approximately 109 and 108 seconds. These wave trains, each with its unique polarization direction, are superimposed to form the electromagnetic wave that is coming from the filament.
Unpolarized light is produced by all common light sources, including the Sun, incandescent and fluorescent lighting, and flames.
