suppose you need to lift 10 boxes of 12kg each to a height of 1.2m. how much work will you do against gravity?​

given mass= 2 kg

height= 10m

g= 9.8.

we know that work down W = FD

= > W = (mg) (D)

= > W = (2* 9.8)(10)

= > W = 196 joules

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
