According to the universe expansion model, objects in the universe are continually moving away from each other. According to the figure above, what evidence would support the universe expansion model?
A) Light moving away from the Earth would experience a red shift and the wavelengths would get longer.
B) Light moving away from the Earth would experience a red shift and the wavelengths would get shorter.
C) Light moving away from the Earth would experience a blue shift and the wavelengths would get longer.
D) Light moving away from the Earth would experience a blue shift and the wavelengths would get shorter.

Explain the difference between each pair of concepts. a. frequency and relative frequency b. percentage and relative frequency a. select the correct choice below. a. frequency is the total number of observations in a data set. relative frequency is the number of times a particular distinct value occurs. b. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of a value to the total number of observations. c. frequency is the total number of observations in a data set. relative frequency is the ratio of the number of times a particular distinct value occurs to the frequency. d. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of two different values.

What are similarities and differences of reflection, refraction, diffraction and absorption?

Awater balloon launcher uses an elastic band with a spring constant of 115 n/m to use thee launcher you stretch thee band back with a balloon n it the water balloons have a mass of 1.3 kg a) if you stretch the band by 0.8 m, what elastic force will the band exert? b) with the band stretched 0.8 m, how much elastic potential energy is stored in the spring? c) if you release the band, it pushes forward. what is the kinetic energy of the balloon when it reaches the natural length of the band? d) what is the speed of the balloon when it reaches the natural length of the band?
