The following statements is FALSE :
a. Dry farming methods replaced the need for windmills.
Explanation:
Dry farming, also called Dryland Farming, the cultivation of crops without irrigation in regions of limited moisture, typically less than 20 inchesof precipitation annually. Moisture control during crop growing consists largely of destruction of weeds and prevention of runoff.The dry farming method was still in use when windmills were established in West TexasDry farming works to conserve soil moisture during long dry periods primarily through a system of tillage, surface protection, and the use of drought-resistant varieties. Dry farming is not a yield maximization strategy; rather it allows nature to dictate the true sustainability of agricultural production in a region. Dry farming's purpose was to conserve limited moisture during dry weather by reducing or even eliminating runoff and evaporation, thereby increasing soil absorption and retention of moisture.

What is the mass of a dragster body with a volume of 150 cm3 if it is made of balsa wood?
Answer:
25.5 g is the answer
Explanation:
The mass of a dragster body with a volume of 150 cm³ made of balsa wood is 0.0225 kilograms or 22.5 grams, calculated by multiplying the given density of balsa wood (150 kg/m³) by the volume in cubic meters (0.00015 m³).
Explanation:The student is asking for the mass of a dragster body if it is made of balsa wood, given its volume is 150 cm³. To find the mass, we use the formula for density, which is mass divided by volume (density = mass/volume). Since the density of balsa wood is provided as approximately 150 kg/m³, we first need to convert the volume from cm³ to m³ by dividing by 1,000,000 (since 1 m³ = 1,000,000 cm³). Therefore, the volume of the dragster body in m³ is 0.00015 m³.
We can now calculate the mass by multiplying the density by the volume: mass = density × volume = 150 kg/m³ × 0.00015 m³, which equals 0.0225 kilograms. Thus, the mass of the balsa wood dragster body is 0.0225 kg or 22.5 grams.
What is the weight of a glider with a mass of 4.9 grams?
Answer:
0.0481 N
Explanation:
The mass of a body is the quantity of matter stored in that body. It is a property that measures resistance to acceleration when a force is applied. The S.I unit of mass is the kilogram (kg).
The weight of a body is the force exerted on that body by gravity. The S.I unit of weight is the Newton (N). The weight of an object can also be defined as the force acting on the object. The formula for weight is:
Weight (W) = Mass (m) × acceleration due to gravity(g).
Giving that: mass (m) = 4.9 g = 0.0049 g and acceleration due to gravity (g) = 9.81 m/s².
Therefore, Weight (W) = 0.0049 × 9.81 = 0.0481 N

Explanation:
The invention of the wheel along with ______ are the roots of mechanical engineering.
A. Tools
B. Shoes
C. Hats
D. Jackets
The invention of the wheel along with tools are the roots of mechanical engineering.
Explanation:
The invention of the wheels and various mechanical implements and tools became the roots of mechanical engineering. This invention led to the great industrial revolutions in the Western World.
The invention of wheel and axle led James Watt to discover steam engine which changed the world it was and hence he is considered as the father of mechanical engineering. Many mechanical mechanisms like the wheel and axle, lever, pulley mechanisms etc were studied during the early civilizations.
The invention of machine tools led to a wide array of new discoveries which makes the world of mechanical engineering, which is always known as the mother of engineering.
Which is an example of a subsystem and system relationship?
A) mechanical toggle, Xbox controller
B) wind, solar
C) television, stereo
D) pencil, pen
The example of a subsystem and system relationship is option
A) mechanical toggle, Xbox controller
Explanation:
Controls and Controllers are known as the mechanical, electro-mechanical, or electronic devices which are used to input signals to change the conditions or values which are in processes or access to buildings, operators, gated areas, etc.When you press and hold the given Shift button, these buttons which are chosen becomes an alternate inputs. Normally, there are three controllers(PID) which are used in any of the process industries inorder to maintain and control the required setpoint. an example of a subsystem and system relationship is a mechanical toggle, Xbox controllerControllers improve the steadiness and state of accuracy by decreasing the steady state error. When the steady state accuracy gets better, the stability also improves.Controllers are also used to help in reducing the unwanted offsets which are produced by the system.A good rule of thumb is to design the horizontal stabilizer so that its area is about 1/6 to 1/8 of the area of the wing. If the area of the wing is 101.25 cm2, which of the following would be a good horizontal stabilizer design?
Answer choices:
Stabilizer with area = 32 cm2.
Stabilizer with area = 20 cm2.
Stabilizer with area = 14 cm2.
Stabilizer with area = 11 cm2.
Answer:
Stabilizer with area = 14 cm2
Explanation:
i dont know why but its right
