The arrow of acceleration would have to be the one that is slightly at an angle and to the right if I am correct, the angle of collision with the side, would cause the puck's acceleration to be not quite directly forward nor directly sideways.

Answer:<em> </em><em>1.04 × 10¹⁶ photons</em>
Explanation:
1) Data:
- E = 3.85mJj (mili joules) = 3.85×10⁻³ J
- λ = 532 nm = 532 × 10⁻⁹ m
2) Physical principles
a) The energy of a photon is given by the equation E = hν.
Where:
- h is Planck's constant 6.62607004 × 10⁻³⁴ J×s
- ν is the freguency of the light
b) The wavelength, λ, and the frequency, are related by the equation:
- ν = c / λ, where c is the speed of light at vacuum, approximately 3.0 × 10⁸ m/s
3) Solution:
- ν = c / λ = 3.0 × 10⁸ m/s / (538 nm) × 10⁹ nm/m = 5.576×10¹⁴ Hz
- E = hν = 6.62607004 × 10⁻³⁴ J×s s × 5.576×10¹⁴ Hz = 3.69 × 10 ⁻¹⁹ J
- Divide the total energy by the energy of one photon to find the number of photons:
3.85×10⁻³ J / 3.69 × 10 ⁻¹⁹ J-photon = 1.04 × 10¹⁶ photons ← answer
Your answer should be B. Irregular
