a book with a mass of 1.8 kg sits on a bookshelf. if it has a gravitational potential energy of 42 J, how high is the Shelf? The acceleration of the gravity is 9.8 m/s^2. A) 2.1 B) 2.4 C) 1.6 D) 0.9

the total distance traveled by the car is

30km + 49km = 79 km .

i had the same answer and put c. deflect randomly in multiple directions.   i looked it up on google and what i found was this;

scattering of light: by small particles and molecules in the atmosphere. different from reflection, where radiation is deflected in one direction, some particles and molecules found in the atmosphere have the ability to scatter solar radiation in all directions.

i know it's kinda annoying when you are just given a google article but this is why i think it is c.   i will try to let you know if i got it right.

you   need to put the sentences as we can not see them. seriously it doesn't take that long
