A roller coaster takes energy to make the first rise, but then it should be able to run the course of the track without any inpu

t of energy. This, however, is not true. Energy continues to be needed. This is because some of the energy is converted to sound energy, and some is given off as heat energy. This is a good example of which law?
the first law of thermodynamics
the second law of thermodynamics
the third law of thermodynamics
the zeroth law of thermodynamics

The sun is 1.5 × 108 km from Earth. The index of refraction for water is 1.349. How much longer would it take light from the sun
tankabanditka [31]

Answer:

175s

Explanation:

time it takes sunlight to reach the earth in  vacuum

C=light speed=299792458m/s

X=1.5x10^8km=1.5x10^11m

c=X/t

T1=X/c

T1=1.5X10^11/299792458=500.34s

time it takes sunlight to reach the earth in  water:

First we calculate the speed of light in water taking into account the refractive index

Cw=299792458m/s/1.349=222233104.5m/s

T2=1.5x10^11/222233104.5m/s=675s

additional time it would take for the light to reach the earth

ΔT=T2-T1=675-500=175s
