For which of these scenarios is total internal reflection possible?

Answers

Answer 1

Answer: TIR is possible whenever light is travelling from a more optically dense medium to a less optically dense medium. You didnt provide any scenarios but just look up refractive indexes of the mediums the light is travelling through and if it is travelling from a more dense to a less dense, TIR is possible

Potassium hydroxide (KOH) and hydrochloric acid (HCl) react in a beaker. They form potassium chloride (KCl) and water (H2O). What type of reaction is this?

Answers

Potassium hydroxide (KOH) and hydrochloric acid (HCl) react in a beaker. They form potassium chloride (KCl) and water (H2O). This type of reaction is a double replacement reaction wherein the two principal reactants exchange after the reaction. The Cl will combine to the K forming KCl and the H will add to the OH forming H2O.

Answer:

B double replacement reaction

Explanation:

PLEASE HELP!!!!!!!!!! Because the boy is slowing down, his velocity decreases over time. Use the final and starting velocities in the data table to calculate his average acceleration. Use the equation , where t is time, ux is initial velocity, vx is final velocity, and ax is acceleration. Use time t = 1.6 seconds, which is calculated using values from the table (1.8 − 0.2).
