Each color of light has a different amplitude
Light changes colors as it goes through the different mediums between the air and our eyes
Each color has a different speed

Answers

Answer 1
I think it is the first one
Answer 2

Answer:

Each color is a different wavelength of light

Explanation:

Our brain mixes information from each receptor which gives contrasting perceptions to each wavelength.

Maggie is trying to find out if the amount of sugar in a liquid affects the amount of time it takes to freeze
A good hypothesis is: The more sugar in the drink the longer it takes to freeze
Conclusion= she concludes that her hypothesis is correct as the unsweetened tea froze the fastest while the root beer took the longest time as it contained the most sugar

Which of the following correctly explains a difference between the Steady State and Big Bang theories?

The Steady State theory says the galaxies are moving; the Big Bang theory says the galaxies are not moving.

The Steady State theory says the universe is getting smaller; the Big Bang theory says the universe is getting bigger.

The Steady State theory is supported by more evidence; the Big Bang theory is supported by less evidence.

The Steady State theory says the universe was always there; the Big Bang theory says the universe

Answers

Answer:

The Steady State theory says the universe is getting smaller; the Big Bang theory says the universe is getting bigger.

Steady state theory: universe is always expanding but maintaining constant average density so basically the ratio will always be 1:1 as as the universe gets bigger more galaxy’s are introduced

Big Bang theory: as the universe gets bigger we have the same galaxy’s and no more get created so in short the matter dilutes as the universe expands

The graph shows the constant speed of a train.
What is the speed of the train?
A. 1200 km/h
B. 300 km/h
C. 75 km/h
D. 4 km/h

Answers

Answer:

75 km/h

Explanation:

Speed = Distance divided by Time.

The train went a distance of 300 km in 4 hours. Therefore, the speed of the train is: 300 divided by 4 = 75 km/h

The speed of the train is equal to 75 km/h. Therefore, option (C) is correct.

What is speed?

The speed of a body can be defined as the distance traveled by an object in a particular time interval. The average speed can be defined as a scalar parameter as it exhibits only the magnitude but not the direction of motion.

The speed of an object can be calculated from the ratio of the distance of the object to the time required to cover that distance.

The equation for the calculation of the speed can be written as follows:

Speed =  distance /time taken

From the graph, at t = 2 h, the distance covered by train = 150 km

At time t = 4 h,  the distance covered by train = 300 km

[tex]\displaystyle Speed = \frac{300-150}{4-2}[/tex]

Speed = 150/2

Speed of the train = 75 Km/h

Therefore, the speed of the train is 75 km/h.
