Answer:
q(ice) = -q(warm water)
Explanation:
Ice removes energy if ice is put in warm water and ice retains the very same amount of energy. Thus the water temperature heat sign is negative, and the ice heat sign is positive.
Yes the Earth is bigger than the Moon.
The moon is one-quarter the size of Earth.
Answer:
The average velocity that these birds travel is 122.22 miles per day to the south.
Explanation:
Speed is the physical quantity that expresses the variation in position of an object and as a function of time. In other words, speed is a physical quantity that expresses the relationship between the space traveled by an object, the time used for it and its direction.
Speed is expressed mathematically as the quotient between distance and time:

where "v" is the speed of the mobile, "d" is the distance traveled by the mobile, and "t" is the time taken by the mobile to carry out the movement.
In this case:
- d= 11,000 miles
- t=3 months= 90 days (
considering that in 1 month there are 30 days)
Replacing:

velocity = 122.22 
<u><em>The average velocity that these birds travel is 122.22 miles per day to the south.</em></u>
