An observer moves at 0.60 c relative to a frame in which clock C is at rest. After accounting for the time that light signals take to travel from clock C, the observer deduces that clock C advances 4.0 s in a certain interval. What is the time measured by a clock at rest in the observer's frame?

A) 2.4 s
B) 3.2 s
C) 5.0 s
D) 6.4 s

Based on the concept of the wave-like nature of light, huygens' theory of light postulates that the more light was "bent" by a substance the slower it would move while traversing across that substance. a) deflection b) interference c) refraction d) resonance

Adiver named jacques observes a bubble of air rising from the bottom of a lake (where the absolute pressure is 3.50 atm) to the surface (where the pressure is 1.00 atm). the temperature at the bottom is 4.00 ∘c, and the temperature at the surface is 23.0 ∘c.what is the ratio of the volume of the bubble as it reaches the surface (vs) to its volume at the bottom (vb)? if jaques were to hold his breath the air in his lungs would be kept at a constant temperature. would it be safe for jacques to hold his breath while ascending from the bottom of the lake to the surface?

When using the scientist method, which step comes last?
