Different things motivate different people. While you may be motivated to get good grades and get a scholarship to an Ivy League college after high school, your classmate's motivation might be to finish high school and go backpacking around the world. Do some research on the Internet and at the school library, and write about the four different types of external and internal motivations: extrinsic, intrinsic, identified, and introjected, and provide examples for each. Also, consider a situation in which you were highly motivated (it does not have to be academic), and describe your motivation and the outcome of the situation.

it has to be b, about 97 percent.

explanation:

heat is transmitted by radiation

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.

not too sure thinking all accelerations are pointed down
