White light moves through a prism and separates into colors in the following order: red, orange, yellow, green, blue, and violet. which of the following choices correctly describes why the violet ray is at the bottom while the red ray is at the top?
a. red and violet light move at the same speed but have different frequencies, so they refract at different angles due to their different frequencies.
b. red and violet light move at the same speed but have different wavelengths, so they refract at different angles due to their different wavelengths.
c. red light moves slowest through glass while violet light moves fastest through glass compared to other visible light. so violet and red refract at different angles.
d. violet light moves slowest through glass while red light moves fastest through glass compared to other visible light. so violet and red refract at different angles.

Your answer is 1.5 hope i  

    m₁v₁ + m₂v₂ = (m₁ + m₂)vmomentum is conserved.the left-hand side of the equation represents the momentum in the system before the collision.the right-hand side represents the momentum in the system after the collisionm₁ and v₁ represents the mass and the velocity of the physics blockm₂ and v₂ represents the mass and velocity of the ball of puttyv represents the final velocity of the combined mass.the question states the two masses stick together. they combined mass has its own velocity with the body mass the sum of the two objects' massestheir combined momentum is (m₁ + m₂)vto find the magitude of (m₁ + m₂)v, we need to add the vectors on the left-hand side of the equation: m₁v₁ + m₂v₂.note the diagram. i have positioned the vectors in accordance with their directions.the magnitude of the resultant can be calculated using the pythagorean theorem since this is a right triangle situation (north and west are perpendicular)|(m₁ + m₂)v| =  √[ (m₁v₁)² + (m₂v₂)² ]|(m₁ + m₂)v| =  √[ (1.5kg·8.0m/s)² + (0.40kg·20m/s)² ]|(m₁ + m₂)v| =  14.4 kg m/sfor two significant figures (assuming that 20m/s is two), this rounds to 14 kg m/s

Because the sun is the biggest and if the sun orbits the earth we will be dead probably
