Speed = distance/time..........................
Answer:
wavelength is 121.58 nm
Explanation:
given data
wavelength = 230 nm = 230 x m
kinetic energy = 3.35 × J
to find out
wavelength of light that triple the maximum kinetic energy of the electron
solution
we know here Einstein's photo electric equation that is given below
hc / λ = φ + K(maximum)
and here φ will be
φ = (hc) / λ - K(max
imum)
put here h = 6.626 x J.s
and 3.0 x m/s
so φ = (6.626 x )( 3.0 x ) / ( 230 x ) - 3.35 x
φ = 6.2995 x J
so here we have given triple the maximum kinetic energy
so
hc / λ = φ + K(maximum)
λ = hc / ( φ + K(maximum) )
λ = (6.626 x )( 3.0 x ) / ( 6.2995 x + 3 ( 3.35 x ))
λ = 1.215817 ×
so wavelength is 121.58 nm

Answer: 12.67 cm, 8 cm
Explanation:
Given
Normal distance of separation of eyes, d(n) = 6 cm
Distance of separation is your eyes, d(y) = 9.5 cm
Angle created during the jump, θ = 0.75°
To solve this, we use the formula,
θ = d/r, where
θ = angle created during the jump
d = separation between the eyes
r = distance from the object
θ = d/r
0.75 = 9.5 / r
r = 9.5 / 0.75
r = 12.67 cm
θ = d/r
0.75 = 6 / r
r = 6 / 0.75
r = 8 cm
Thus, the object is 12.67 cm far away in your own "unique" eyes, and just 8 cm further away to the normal person eye
