Explain why a black and white aeronautical map would be difficult to use

1 answer:

5 0

Aeronautical maps are usually meant to be used by pilots and air aviation professionals in other to navigate or traverse though the sky. With various elements such as vegetation, hills, valleys being depicted by color coded keys or legend. Hence, the absence of color on an aeronautical map make the <em>representation of elements very difficult</em>.

Visual map interpretation is usually aided by the use of legends. The legend hold the key to the elements which are represented on the map. Usually, a combination of colors and shapes makes up the legend and makes map interpretation easy.

Therefore, the absence of various color palletes for representation on a black and white aeronautical map will make it difficult to use.

A 0.150 kg ball is fired from toy gun with a spring with spring constant k- 150 N/m, initially compressed by a distance x 0.050

Degger [83]

Answer:

v = 4.264 m/s

Explanation:

It is given that,

Mass of the ball, m = 0.15 kg

Spring constant of the spring, k = 150 N/m

The spring is compressed by a distance, x = 0.05 m

The pellet's initial velocity is at an angle θ (θ < 90) above the horizontal.

Let v is the final speed of the projectile when it is at a distance h = 0.800 m below its initial height. It can be calculated using the conservation of energy as :

$E_i=E_f$

$\dfrac{1}{2}kx^2+mgh=\dfrac{1}{2}mv^2$

$\dfrac{1}{2}\times 150\times (0.05)^2+0.15\times 9.8\times 0.8=\dfrac{1}{2}\times 0.15\times v^2$

v = 4.264 m/s

So, the final speed of the projectile is 4.264 m/s. Hence, this is the required solution.

All of the following are factors affecting flow rate except what?

faust18 [17]

Answer:

c. Vessel side holes

Explanation:

The "Poiseuille formula" which is given by $\\\begin{aligned} \small Q& = \small \frac{\pi r^4}{8 \eta}.\frac{\Delta P}{\Delta L}\\\end{aligned}$ describes the volumetric flow rate ( $\small Q$ ) through tubular sections.
Here, $\Delta P,\,\, \Delta L,\,\, r,\,\, \eta$ represent the injection pressure difference, the length of the section, the radius of the section and the viscosity index of the fluid that flows through the section respectively.
With this, one can confirm that all the factors except the vessel side holes affect the flow rate.
Side holes, however, are a factor that could give a measure of how much volume would flow to a particular location. In such a situation the flow rate remains unchanged and one location would receive a lower volume (not the whole) as some volume would spill out at the side holes.

In January 2017, when Clemson won the football championship, Coach Dabo Swinney decided to buy pizza for all students at Clemson

ale4655 [162]

Answer:

Explanation:

We shall represent each move of coach in vector form , considering unit vector i towards east and unit vector j towards north .

he drove 100 m North

First displacement D₁ = 100 j

200 m East to reach the 133

second displacement D₂ = 200 i

500 m North to reach Papa John's

third displacement

D₃ = 500 j

Total displacement ( resultant displacement )

= D₁ + D₂ + D₃

= 100 j + 200 i + 500 j

= 200 i + 600 j

magnitude of resultant displacement

= √ ( 200² + 600² )

= √ 40000 + 360000

= 632.45 m
