Answer:
25N
Explanation:
Assuming the lab is on earth:
w = mg = 2.5 (9.81) = 25N
675g/cm³ is the density of the liquid
Here we have given that
density of wood be ρ.
the volume of the block be V
The volume of the block =1/4 v
The volume of the immersed block (v) =V-1/4V=3/4V
We know the weight of the block = the weight of the water displaced by the submerged part of the block.
i.e. V x ρ x g
= 3/4 x900g/cm³
= 675g/cm³
Density is a measure of mass divided by the volume of an object. Defined as mass per unit volume. here from the above equation we have substituted the given value and we got the answer as 675g/cm³

Answer:
its the teal/second from the left one
Explanation:
Answer:
16,506 ft²
Explanation:
There are different ways you can divide the area using rectangles and circles. One way is to find the area of the entire width and length, then subtract the empty areas in the corners.
If we take the empty areas and put them together, we find their area is the area of a square minus the area of a circle.
A = (2r)² − πr²
A = 4r² − πr²
A = (4 − π) r²
So the area of the rink is:
A = WL − (4 − π) r²
A = (85)(200) − (4 − π) (24)²
A ≈ 16,506 ft²
