a). The gravitational forces between the Earth and the Sun bends the Earth's motion along a curving path instead of a straight line.

b). The gravitational forces between the Earth and a falling rock make the rock fall faster and faster.

c). The force of a pressurized stream of hot air makes a balloon get rounder and bigger.

d). The gravitational forces between the Earth and a rock tossed straight up make the rock go slower and slower, and eventually stop. (In the next instant, it starts falling, as described in answer-b.))

e). The acoustic and emotional force of your mother's voice 15 minutes before the school-bus arrives causes you to turn over, sit up, and start putting on your socks.

A reaction that releases heat is: endothermic exothermic none of the above

Bas_tet [7]

Answer:

Exothermic reaction

Explanation:

A reaction that releases heat is known as an exothermic reaction.
Reactions can be classified as either exothermic or endothermic depending on whether they release or absorb heat from the surrounding.
A reaction that absorbs or gains heat from the surrounding is known as endothermic reaction.
On the other hand, if a reaction releases heat to the surrounding is known as exothermic reaction.
An exothermic reactions results to an increase in temperature of a solution while an endothermic reaction results to a decrease in the temperature of a solution.

Explain in details the concept of economic geography

vova2212 [387]

Answer:

In the words of Hartshorn and Alexander: “Economic Geography is the study of the spatial variation on the earth’s surface of activities related to producing, exchanging and consuming goods and services. Whenever possible the goal is to develop generalizations and theories to account for these spatial variations.”

What happens when two forces act in the same direction?

Wewaii [24]

Using the picture provided the forces are added together, because they are putting force on an object the same direction, thus the forces are added.

When making maps of the large-scale universe, astronomers estimate distances to the vast majority of galaxies by using:

Vesnalui [34]

Answer:

The comoving distance and the proper distance scale

Explanation:

The comoving distance scale removes the effects of the expansion of the universe, which leaves us with a distance that does not change in time due to the expansion of space (since space is constantly expanding). The comoving distance and proper distance are defined to be equal at the present time; therefore, the ratio of proper distance to comoving distance now is 1. The scale factor is sometimes not equal to 1. The distance between masses in the universe may change due to other, local factors like the motion of a galaxy within a cluster. Finally, we note that the expansion of the Universe results in the proper distance changing, but the comoving distance is unchanged by an expanding universe.
