If you put a cup of hot chocolate at 90c on a table in a room kept at 25c you know it will cool down. How cool will the hot choc
bagirrra123 [75]

Answer:

Explanation:

Assuming we have a two hot liquid like 70°C tea and 30°C water, the tea will cool down but not to 30°C but to an equilibrium temperature say 40°C

But in this case, the temperature of the chocolate will drop almost to the room temperature eventually,

The heat in the chocolate will even out into the room temperature and the room will get slightly warmer until the are both in equilibrium temperature. But you won't notice this little change but if you go out of the room, you might notice that change...

So this little fraction is not always notice, so we will still considered it as the room temperature

Which law of motion accounts for the following statement?
m_a_m_a [10]

First, you need forces attracting the Sun and Earth toward each other.  That's described by Newton's law of universal gravitation.

Then you need the description of how that force causes the planet to move in a circular path.  The best choice is Newton's <em>Second law</em> of motion: F = m A .
