False does not last that long
Answer:
Law of refraction
Explanation:
An experiment to analyze the refraction of light in water can easily be performed with a laser pointer and protractor.
We throw the fishing rod line into the water, place the protractor at the point where the line touches the water and use the direction of the line for the direction of the laser pointer (on), the laser is visible by the reflection on the particles in the air.
The vertical line is called Normal and all angles must be measured with respect to this reference in optics.
Having these angles and the refractive index of water we can use the law of refraction
n₁ sin θ₁ = n₂ sin θ₂
θ₂ =
we can repeat several times to analyze several different input points (different angles) and to decrease the errors in the measurements.
the refractive index of air is n1 = 1 and n2= 1.33 (water)
Answer:
the answer is 0
Explanation:
The acceleration of a car that maintains a constant velocity of 100 km/h for 100s is zero. Acceleration is a change in velocity. Thus, if velocity is constant, that means there is no change and velocity stays the same.
Answer:
A. It uses less energy to make something from recycled materials than from new materials.
Explanation:
I think it is this one because it is the only one that is not harmful to the environment. Also, I took the test a few minutes ago.
Answer:
Matter can exist in four different states: solids, liquids, gases and plasma.
