Brainliest!!! A student wanted to answer the question, “How does the amount of glycerin affect the size of a bubble blown with s

oap mixture of water, dish soap and glycerin?”. She decided to test the amount of glycerin added to a soap mixture and used 1 drop, 2, drops, 3 drops, and 4 drops. She would add 10 mL of soap to 50 mL of water for each bubble solution. She measured the size (cm) of the bubble produced for each solution.

It’s Glycerin because an independent variable is defined as the variable that is changed or controlled in a scientific experiment. It represents the cause or reason for an outcome. A change in the independent variable directly causes a change in the dependent variable. The effect on the dependent variable is measured and recorded.

Light is shone on a diffraction grating
Pani-rosa [81]

Answer:

    λ = 482.05 nm

Explanation:

The diffraction phenomenon and the diffraction grating is described by the expression

         d sin θ = m λ

where d is the distance between two consecutive slits, λ the wavelength and m an integer representing the order of diffraction

in this case they indicate the distance between slits, the angle and the order of diffraction

         λ = \frac{d sin \theta }{m}d sin θ / m

let's calculate

         λ = 1.00 10⁻⁶ sin 74.6 / 2

         λ = 4.82048 10⁻⁷ m

Let's reduce to nm

         λ = 4.82048 10⁻⁷ m (10⁹ nm / 1 m)

         λ = 482.05 nm

How does the water cycle influence weather in your area? Use complete sentences and a specific example from your experience.
Charra [1.4K]

Evaporation is the process by which water changes from a liquid to a gas or vapor. Evaporation is the primary pathway that water moves from the liquid state back into the water cycle as atmospheric water vapor. Studies have shown that the oceans, seas, lakes, and rivers provide nearly 90 percent of the moisture in the atmosphere via evaporation, with the remaining 10 percent being contributed by plant transpiration.
