Very funny. Can I do all your homework for you?
(a) The electron kinetic energy is

which can be converted into Joule by keeping in mind that

So that we find

The kinetic energy of the electron is related to its momentum p by:

where m is the electron mass. Re-arranging the equation, we find

And now we can use De Broglie's relationship to find its wavelength:

where h is the Planck constant.
(b) By using the same procedure of part (a), we can convert the photon energy into Joules:

The energy of a photon is related to its frequency f by:

where h is the Planck constant. Re-arranging the equation, we find

And now we can use the relationship between frequency f, speed of light c and wavelength

of a photon, to find its wavelength:
Answer: 45 joules of energy
Explanation:
The water formed on the surface of the water evaporation loss (evaporation), consisting of plant transpiration water loss (transpiration) is called. Soil near the plant and the resulting water loss is called by evapotranspiration.
Answer:
1058.78 ft/sec
Explanation:
Horizontal Component of Velocity; This is the velocity of a body that act on the horizontal axis. I.e Velocity along x-axis
The horizontal velocity of a body can be calculated as shown below.\
Vh = Vcos∅.......................... Equation 1
Where Vh = horizontal component of the velocity, V = The velocity acting between the horizontal and the vertical axis, ∅ = Angle the velocity make with the horizontal.
Given: V = 1178 ft/sec, ∅ = 26°
Substitute into equation 1
Vh = 1178cos26
Vh = 1178(0.8988)
Vh = 1058.78 ft/sec
Hence the horizontal component of the velocity = 1058.78 ft/sec
