430m. We use the displacement formula x=v*t+1/2*a*t^2. Set upward to be the positive direction, so v=6m/s, a=-g=-9.8m/s^2 (gravity is pulling the object down), and t=10s. The displacement is -h(it's negative because the ending point is the ground, which is negative relative to the starting point). -h=60-4.9*100, h=430 m.
The mass of a neutron is:

Since we know its speed, we can calculate the neutron's momentum:

The problem says the photon has the same momentum of the neutron, p. The photon momentum is given by

where h is the Planck constant, and

is the photon wavelength. If we re-arrange the equation and we use the momentum we found before, we can calculate the photon's wavelength:

And since we know the photon travels at speed of light c, we can now calculate the photon frequency:
Answer:
If it turns the paper blue it would have to be a base.
Explanation:
I hope that answers your question!
