you burn a log on a fire. you use the fire to warm yourself and to you see to read a book. what energy transformation is taking place?

a. nuclear energy is transformed to light energy and chemical energy.
b. chemical energy is transformed to nuclear energy and heat energy.
c. chemical energy is transformed to light energy and heat energy.
d. nuclear energy is transformed to light energy and heat energy.

C.Chemical energy is transformed to light energy and heat energy.

Explanation:

Here it is given that the fire is used for two objectives

1) To warm yourself

which means we need some thermal energy so that we get the warmth from it.

2) To see to read the book

here in order read the book we required light of sufficient intensity so here we require light energy for this.

so from above requirements of energy we can say that here the energy contained in the wooden block is converted into the above forms

Also we know that energy contained in the wooden block is in the form of chemical energy so here correct answer will be

C.Chemical energy is transformed to light energy and heat energy.

speed

ratio of distance traveled to time interval

net force

vector sum of forces on object

object

source of diverging light rays either luminous or illuminated

don't remove my answer im trying my best to answer them

explanation:

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.
