ANSWER:
IV, Type of dish detergent. DV, height of foam. CV, type of container, amount of water in container, temperature of water, time the container is agitated.
Explanation:
Independent variable(IV)- what you change during the experiment.
dependent variable(DV)- what you're measuring during an experiment. The dependent variable is DEPENDENT because it's results DEPEND on the independent variable at play.
Constant variables(CV)- things that do not change in order to isolate the tested variables as much as possible.
Explanation:
a = (Vf-Vi)/t
= (10m/s - 15m/s)/2s
a = -5 / 2 m/s^2
• so the dog diaccelerate at the rate of 5/2 m/s^2

The exact magnification of the objects is calculated by dividing the cinema. We calculate it by diving the erect image size by the object size. From the given above, we find the exact magnification by dividing 5.0 cm by 1.0 cm. Thus, the answer would be 5.
Answer:
b. +1
Explanation:
Given,
Speed of light in vacuum = c
Speed of light in any medium = v
Refractive index = n
To find: minimum value of refractive index.
We know that,
We know that speed of light in vacuum is fixed and there is nothing in this universe faster than that so value of c is fixed.
Now, speed of light in any medium can not be greater than the speed of light in vacuum. It means,
c ≥ v
So that means the maximum speed of light in any medium can only be equal to c. Thus minimum value of refractive index is,
n = +1
