Most of the heat that's melting the ice comes from the foil. That's because metals are good conductors of heat. Heat from the surroundings flows into the foil and then from the foil into the ice. Draw arrows to show the amount and direction of heat transfer between the foil and the ice. Plato

hi,

what occurs during a solar eclipse?

there are small tides across earth.

the moon is between earth and the sun.

p.s. im not sure if the first answer is correct because during a solar ecliphse there are spring tides and i dont know if they are the same.

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form
