Answer:
Pink block = 1.4 cm
Green block= 1.5 cm
Blue block= 1.7 cm
Explanation:
Hi, the ruler is in centimeters, from left to right each long line ( the ones with the number ) is a centimeter.
Since 10 millimeter equals 1 centimeter each short line is a millimeter (0.1 cm)
Knowing this, the measures of each block are.
Pink block = 1.4 cm
Green block= 1.5 cm
Blue block= 1.7 cm

Answer:
h_f = 15 ft, so option A is correct
Explanation:
The formula for head loss is given by;
h_f = [10.44•L•Q^(1.85)]/(C^(1.85))•D^(4.8655))
Where;
h_f is head loss due to friction in ft
L is length of pipe in ft
Q is flow rate of water in gpm
C is hazen Williams constant
D is diameter of pipe in inches
We are given;
L = 1,800 ft
Q = 600 gpm
C = 120
D = 8 inches
So, plugging in these values into the equation, we have;
h_f = [10.44*1800*600^(1.85)]/(120^(1.85))*8^(4.8655))
h_f = 14.896 ft.
So, h_f is approximately 15 ft
Explanation: For main group elements, the number of valence electrons is the same in every element in the same group. Group 1 elements have 1 valence electron in the s orbital.
Answer:
The world wars. Most notably world War II
Explanation:
The demand for aircrafts during these events led to extensive research into the design of aircrafts. Aircraft advanced within these years from a simple design to a more complex design; capable of carrying fire power and even became bomb equipped. Also, the material of choice of production moved from wood to metal and the engine was improved on to gain more speed and maneuverability.
