Answer:

E=5.544*10^{-26} J

Step-by-step explanation:

The equation for photon energy is given by:

E=hf

Where:

h=Planck\hspace{3}constant=6.6*10^{-34} \\f=Frequency\hspace{3}of\hspace{3}the\hspace{3}wave=84000000Hz

This equation telling us that the higher the frequency of the photon, the greater its energy. And the longer the photon wavelength, the lower its energy.

So, replacing the data provided in the previous equation:

E=(6.6*10^{-34} )*(84000000)=5.544*10^{-26} J

If you draw a net for a cylinder, such as a soup can, how many two-dimensional geometric shapes would this net have?
Nezavi [6.7K]

Answer:

3.

If you were to “unroll” a can of soup, you would end up with two circles and one rectangle.

Thats why when you are finding the surface area of a cylinder, you need to multiply the area of the circle by 2. And also you need to find the area of the rectangle. Then you add the areas all up.

please mark me brainlies :)

A residual plot has data points that are all very close to the x-axis. What does this say about the data?
Afina-wow [57]

Answer:

B

Step-by-step explanation:

because, the closer the data points are to the x axis on a residual plot with no definite shape means that a linear model is appropriate for this data set
