The component of the total velocity in the x - direction is 6.96 m/s.
The component of the total velocity in the y - direction is 2.95 m/s.
<h3>
Component of the velocity in x direction </h3>
The component of the total velocity in the x - direction is calculated as follows;
v(x) = vtot cosθ
where;
- vtot is total velocity
- v(x) is velocity in x direction
v(x) = 7.56 x cos(23)
v(x) = 6.96 m/s
<h3>
Component of the velocity in y - direction</h3>
v(y) = vtot sinθ
v(y) = 7.56 x sin(23)
v(y) = 2.95 m/s

Answer:
C a basketball player pushes into another one and they both fall to the left
Explanation:
I believe his is the answer because I don't see any force and not enough reaction
I don't see any units of measurement or speed I don't see anything
If the light of wavelength 700 nm strikes such a photocathode the maximum kinetic energy, in eV, of the emitted electrons is 0.558 eV.
so - $KE_{max} = hc/lembda} work
threshold when KE = 0
hc/lambda = work = 1240/900=1.38 eV
b) Kemax = hc/lambda - work = 1240/640 -1.38=0.558 eV
What is photocathode?
- A photocathode electrolyte interface can be used in a photoelectrolysis cell as the primary light-harvesting junction (in conjunction with an appropriate electrochemical anode) or as an optically complementary photoactive half-cell in a tandem photoelectrode photoelectrolysis cell (Hamnett, 1982; Kocha et al, 1994).
- In the case of the former, the electrode should ideally harvest photon energy across the majority of the solar spectrum in order to achieve the highest energy conversion efficiency possible.
- In the latter case, however, the photocathode may only be active in a specific band of the solar spectrum in order to generate a cathodic photocurrent sufficient to match the current generated in the photoanodic half-cell.

As for me, the reson why scientists usually write reports about their investigations is because they want to <span>d. to communicate their work to other scientist. As far as I am concerned in this sphere they have to get many other opnions besides their own in order to complete or expand one that they have made up. Hope it helps :)</span>
