mass of ice is 
Latent heat of fusion 
The heat capacity of water is 
Suppose water is at 
and it reaches to 
to melt the ice
the heat released by water must be equivalent to heat absorbed by the ice
Answer:
The answer is A
Explanation:
Someone shouting to you from across a room
Answer:
D.
Explanation:
All our gas giants have rings
If you neglect air resistance, then you can solve for the horizontal distance using the formula:
dx=vixt
Where:
dx = horizontal distance
vix = initial horizontal velocity
t = time in flight
Now you can see that you have all the given you need.
vix= 2km/h
t = 0.25 hours
We use hours because you need the units to be the same. So just plug that in your equation and you will have your answer:
dx = vixt
=(2km/h)(0.25h)
=0.5km
This means that the answer to your question is B.
