Answer:
"There are two laws of floatation. The first one states that the weight of a floating body is equal to the weight of the liquid displaced. The second one states that the centre of gravity of a floating body and the centre of buoyancy are in the same vertical line." - quora
Step-by-step explanation:
I think it might be 56y^2 but I could be wrong
Answer:
=5.2/1.3
=4
16/4
=4
Step-by-step explanation:
first find the ratio of 5.2 to 1.3 by dividing the 2 numbers. That gave me 4 since you want EF I just did 16 divided by 4 which gave me 4.
EF=4
By the 6 trigonometric ratios in a right triangle
(sine, cosine, tangent, cotangent, secant, cosecant)
we have the following:

So,

sin20° must be given, or can be found using a calculator:
Using the calculator of our pc: Calculator- view:Scientific- press 20 then sin button, we find : sin20°=0.342
