Answer:
In the first law, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.
The formula for the critical angle is:
sin (critical angle) = refractive index of solution / refractive index of air
=> refractive index of solution / refrative index of air = sin (48°)
=> refractive index of solution / refractive index of air = 0.7431
=> refractive index of solution = 0.7431 * refractive index of air
=> refractive index of solution = 0.7431 * 1.00
=> refractive index of solution = 0.74
Answser: 0.74

Explanation: kinetic energy being transferred from one object to another. Kinetic energy is the energy of mass in motion. The kinetic energy of an object is the energy it has because of its motion.
Mass: the amount of matter an object contains
Weight: mass•acceleration due to gravity(9.8m/s) / the force of gravity acting on an object
