Answer:
That when you leave the ice setting without foil, it melts slower. When you put the piece of ice in the foil it melts faster than just letting it set without foil. I really hope this helps.

Answer:
A
Explanation
i think its a not 100% sure though.
Given:
d = 2.70 g/cm³, the density
M = 5.31 lbs, the mass
t = 0.0130 mm, thickness
Convert all data into SI units.
d = (2.70 g/cm³)*(1/1000 kg/g)*(10² cm/m)³
= 2.7 x 10³ kg/m³
M = (5.31 lb)*(0.543592 kg/lb)
= 2.4086 kg
t = (0.013 mm)*(10⁻³ m/mm)
= 1.3 x 10⁻⁴ m
Let the surface area f the foil be A m².
Then the mass of the foil is
M = d*A*t
= (2.7 x 10³ kg/m³)*(A m²)*(1.3 x 10⁻⁴ m)
= 0.351A kg
Because the mass is 2.4086 kg, therefore
A = 2.4086/0.351
= 6.862 m²
Answer: The surface area is 6.862 m².
Friction is the force that helps stop objects from sliding forever and ever. soccer players use friction to push themselves forward with their feet to run and start accelerating. if they want to stop, they can put their feet on the ground roughly to slow them down immediately from the rough terrain and the surface of their shoes
Competition can result in territory obtained by one kind of birds, causing the other birds to find somewhere else. There can also be competition in food where one type of bird takes over resulting in other birds finding another habitat leading to a decrease and limitation in the size of a bird population.
