Please help me with my physics homework I don’t understand this concept

Pepe and alfredo are resting on an offshore raft after a swim. they estimate that 3.00 m separates a trough and an adjacent cres

Orlov [11]

The velocity (V) of a wave is the frequency (F) times the wave length (lambda):

V = F * lamda

lambda is the distance from crest to crest which is twice the distance from crest to trough.

=> lamba = 2 * 3.00 m = 6.00 m

F = number of waves / time = 13.0 waves / 20.2 s

Now you can plug in the values in the formula of V:

V = 6.00 m/wave* 13.0 waves / 20.2 s = 3.86 m/s

Answer: 3.86 m/s

What is a measure of the consistency and stability of test scores when readministered at different times?

tino4ka555 [31]

Answer:

Reliability is typically shown as a reliability coefficient created in a calculation to determine the reliability, or consistency, of scores, such as a measure of the amount of consistency between two sets of scores from different administrations from the same group of students.

When hydrogen is heated or subjected to an electric discharge, it emits light with specific visible wavelengths. A diffraction g

BartSMP [9]

To solve this problem we will apply the concepts related to the double slit-experiment. For which we will relate the distance between the Slits and the Diffraction Angle with the order of the bright fringe and the wavelength, this is mathematically given as,

$d sin\theta = m\lambda$
