Answer:
= 1.6
Explanation:
= Angle of incidence = 65.9°
= Angle of refraction = 34.8°
= Index of refraction of air = 1
= Index of refraction of glass = ?
Using Snell's law
Sin
=

(1) Sin65.9 =
Sin34.8
= 1.6
Well they could go down a hill to gain more kinetic energy.
Answer:
Force(N)= Mass(kg) x Acceleration(m/s^2)
Explanation:
968 j or kg because it cannot lose any of it energy and cannot gain any extra mass from nothing
