Answer: Some challenges that I could see would be the walls, possibly a moat, tar, and the towers.
Explanation: The wall is obliviously a main problem, trying to get over it or through it is a difficult challenge. The moat (if it has one) means that there is more than likely only one way to get in or out. If it does have tar it means that the attackers are going to be put in a "sticky situation" And finally the towers, they have people at the top shooting arrows down at you, or throwing things at you.
So far, none of them apply.
A big part of the reason is that we can't see the statements OR the map.
Answer:
volume of a rectangular prism = 77.616
Given:
length = 5.6 cm
width = 2.1 cm
height =6.6 cm
To find:
volume of a rectangular prism = ?
Formula:
volume of a rectangular prism = length × width × height
Solution:
volume of a rectangular prism = length × width × height
volume of a rectangular prism = 5.6 × 2.1 ×6.6
volume of a rectangular prism = 77.616
Answer:
Explanation:
Given that
At 17°C ,Lo= 20.09 cm
At 306°C ,L= 20.18 cm
ΔL= 200.18 - 20.09 = 0.09 cm
ΔT = 306 - 17 = 289°C
We know that
ΔL = L α ΔT
α =coefficient of linear expansion
ΔL = Lo x α x ΔT
0.09 = 20.09 x α x 289
Coefficient of linear expansion,
Answer:
(I). The effective cross sectional area of the capillaries is 0.188 m².
(II). The approximate number of capillaries is
Explanation:
Given that,
Radius of aorta = 10 mm
Speed = 300 mm/s
Radius of capillary
Speed of blood
(I). We need to calculate the effective cross sectional area of the capillaries
Using continuity equation
Where. v₁ = speed of blood in capillarity
A₂ = area of cross section of aorta
v₂ =speed of blood in aorta
Put the value into the formula
(II). We need to calculate the approximate number of capillaries
Using formula of area of cross section
Put the value into the formula
Hence, (I). The effective cross sectional area of the capillaries is 0.188 m².
(II). The approximate number of capillaries is
