Yes

Explanation:

From the graph, we can deduce that the wavelength changes with the speed of the wave.

This is a simple linear graph. A linear graph has a steady gradient and it shows two variables that increases proportionately.

Using the graph, we can establish that as the wavelength of the wave increases the time taken for one wave to pass through increases.

The speed of a wave is given as:

V = fλ

f is the frequency of the wave i.e the number of waves that passes through a point per unit of time

λ is the wavelength of the wave

The vertical axis on the graph shows the time for 1 wave trip, this is the wave period, T

f = $\frac{1}{T}$

Therefore;

speed of the wave = $\frac{λ}{T}$

This can be evaluated by solving slope of the graph and finding the inverse.

We can see that as the speed of the wave changes, the wavelength will change.

What was the major shortcoming of rutherford’s model of the atom?

lisabon 2012 [21]

The major shortcoming of Rutherford's model was that it was incomplete. It did not explain how the atom's negatively charged electrons are distrubuted in the space surronding its positively charged nucleus. A form of energy that exhibits wavelike behavior as it travels through space

A dock worker loading crates on a ship finds that a 27 kg crate, initially at rest on a horizontal surface, requires a 80 N hori

Aleksandr-060686 [28]

Answer:0.302

Explanation:

Given

mass of crate m=27 kg

Force required to set crate in motion is 80 N

Once the crate is set in motion 56 N is require to move it with constant velocity

i.e. 80 N is the amount of force needed to just overcome static friction and 56 is the kinetic friction force

thus

$f_s(static\ friction)=\mu \cdot N$

where $\mu$ is the coefficient of static friction and N is Normal reaction

$N=mg$

$f_s=\mu mg$

$\mu mg=80$

$\mu =\frac{80}{27\times 9.8}$

$\mu =0.302$

Pepsi [2]

Answer:

Explanation:

b) Gravity reduces the initial upward velocity to zero in a time of

t = v/g = 40/10 = 4 s

a) h = v₀t + ½gt² = 40(4) + ½(-10)4² = 80 m

v² = u² + 2as

h = (0² - 40²) / 2(-10) = 80 m

The interference pattern seen when light passes through narrow, closely spaced slits, is due to

Lelu [443]

<h2>Answer: Diffraction</h2><h2 />

Diffraction is a characteristic phenomenon that occurs in all types of waves .

In this sense, <u>diffraction</u> happens when a wave (the light in this case) meets an obstacle or a slit .When this occurs, the light bends around the corners of the obstacle or passes through the opening of the slit that acts as an obstacle, forming <u><em>multiple patterns</em></u> with the shape of the aperture of the slit.

Note that the principal condition for the occurrence of this phenomena is that <u>the obstacle must be comparable in size (similar size) to the size of the wavelength. </u>
