The volume of the submarine never changes. When the tanks are completely full of air a submarine with a
volume of 2 X 10' m' has a total mass of 1.5 * 10° kg. The density of the seawater is 10 kg m.
To make that submarine float neutrally, and neither float nor sink in the ocean, what volume of water does that
submarine need to add to its tanks? (Ignore the mass of the replaced air

let's fu(!

step-by-step explanation:

“ a line segment that has the endpoints on the circle and passes through the midpoint is called the diameter. the diameter is twice the size of the radius. a line segment that has its endpoints on the circular border but does not pass through the midpoint is called a chord. a circle is the same as 360 small circle up the number 0 . i hope this .

yx = 36

step-by-step explanation:

cos f = opposite side/ hypotenuse

cos f = yw / yx

we know cos f = 4/9 and yw =16

4/9 = 16/yx

multiply each side by yx

4/9 yx = 16/ yx * yx

4/9 yx = 16

multiply each side by 9/4

9/4 * 4/9 yx = 16 *9/4

yx = 36

i think it is d. hope this
