Answer:
Workdone = 2450Joules
Step-by-step explanation:
Let the top of the aquarium be at height 0.
Let the bottom of the aquarium be at height 1
F = mg = 2p◇x × g
F= 2000◇x × 9.8
F = 19600◇x
Workdone = 19600xdx
Total workdone = Integral (limits 0.5 -0)19600×dx
Total work = [9800x^2]^0.5
Total work= 9800× 0.5^2 = 2450 Joules
32 is ur answer
sorry if its wrong
Im bad at this
Answer:
<h2>Side YZ is 8 units long.</h2>
Step-by-step explanation:
We can deduct form the graph that segment WO is a radius of the circle and XY is its diameters.
By given, we know that
, which means
, by radius definition.
An important characteristic of tangents about circles is that the tangent is always is perpendicular to the radius, that means
and
is a right triangle, that means we can use Pythagorean's Theorem to find the side YZ.

Where
is the hypothenuse and
,
are legs of the triangle.
Replacing all given values, we have

However, by sum of segments, we have
, where
and 

Therefore, side YZ is 8 units long.
Y = -1
1 - 13(-1)
= 1 - (-13)
= 14
