Plz help me im really confused. The questions are in the second pic and the vehicles are in the first the fetures are in the las
t 3 the check mars are just to see which data for that vehicle is safer. The check marks are just to see which data is safer for that car.

Answer:
The recoil speed is
Solution:
Wavelength of a blue-green photon,
Now, the energy associated with the blue-green photon:
where
h = Planck's constant
C = speed of light ion vacuum
Also, we know that the recoil speed can be calculated by the KInetic energy which is equal to the Energy of the blue-green photon:
where
= velocity of Hydrogen atom
= mass of H-atom
Now,
Answer:
I = 4.38 x 10⁻⁷ A
Explanation:
Given,
speed = 4.47 x 10⁴ m/s
radius of the circular path, r = 2.59 x 10⁻⁹ m
effective current = ?
The current represented by the orbiting electron is equal to
f is the frequency
q is charge of electron
we know,
f = 2.74 x 10¹² Hz
now,
I = 4.38 x 10⁻⁷ A
Hence, the effective current associated with the orbiting electron is equal to I = 4.38 x 10⁻⁷ A
