It is less dense than the water above it and so it the heated less dense water rises upwards to replace the denser water and the denser water falls below to the heating element below, and this also becomes less dense and the circle continues, thus setting up the convection current.

Similar principle is applied in convection current for land and sea breezes.

Projectile A is launched horizontally at a speed of 20. Meters per second from the top of a cliff and strikes a level surface be
miv72 [106K]

consider the motion of projectile A in vertical direction :

v₀ = initial velocity of projectile A in vertical direction = 0 m/s         (since the projectile was launched horizontally)

a = acceleration of the projectile = g = acceleration due to gravity = 9.8 m/s²

t = time of travel for projectile A = 3.0 seconds

Y = vertical displacement of projectile A = height of the cliff = h = ?

using the kinematics equation along the vertical direction as

Y = v₀ t + (0.5) a t²

h = (0) (3.0) + (0.5) (9.8) (3.0)²

h = 44.1 m

What is the surface area to volume ratio of this cube
tamaranim1 [39]

I can't see that cube from here.

But if the length of the side of the cube is ' K ' units,
then the surface area of the cube is  6K² units², and
the volume of the cube is  K³ units³.

The ratio of the surface area to the volume is

               (6K² units²) / (K³ units³)  =  (6) / (K units) .

So for example, if the side of the cube is 2 inches, then
the ratio of surface area to volume is  "3 per inch".

That's the answer.  I did the whole thing in order to earn
the points, but I don't expect you to understand much of it,
because I see from your username that you suck at math.
I'm sorry you decided that.  Now that you've put up the
brick wall, it'll be even harder for any math to find its way
in there, and you'll miss out on a lot of the fun.
