Answer:
To maintain enough time to prevent a collision, a system operating in air traffic where aircraft speed does not
fall below 100 km/h (most medium-sized UAVs and GA aircraft) will need to be able to detect obstacles which
subtend an arc-width of as small as 0.125 mra
C. Each gender has differing attraction cues and priorities.
<h3>Why do men and women exhibit different preferences in mate selection?</h3>
Men and women exhibit different preferences in mate selection because both have different attraction cues and priorities for their partner. These cues and priorities leads to difference in preference of life partner.
So we can conclude that Each gender has differing attraction cues and priorities.

Weight of an object is given by the formula W = m x g , where
m : mass of the object
g : gravitational acceleration
It is <u>independent of the horizontal </u><u>acceleration</u>.
<h3>What do we mean by weight of an object?</h3>
Weight is a gauge of how strongly gravity is<u> pulling something down.</u> It is dependent on the object's mass, or how much matter it consists of. It also depends on the <u>object's uniformly distributed</u> downward acceleration caused by gravity.
This equation can be used to express weight:
W = m x g
<h3>What is the difference between weight and mass of an object?</h3>
In everyday speech, the phrases "mass" and "weight" are frequently used interchangeably; nevertheless, the two concepts don't have the same meaning. In contrast to weight, which is a <u>measurement of</u> how the <u>force</u> of gravity works upon a mass, mass is the <u>amount of substance</u> in a material.

The basic relationship between frequency and wavelength for light (which is an electromagnetic wave) is
![c= f \lambda](https://tex.z-dn.net/?f=c%3D%20f%20%5Clambda)
where c is the speed of light, f the frequency and
![\lambda](https://tex.z-dn.net/?f=%5Clambda)
the wavelength of the wave.
Using
![\lambda=4.5 \cdot 10^{-7} m](https://tex.z-dn.net/?f=%5Clambda%3D4.5%20%5Ccdot%2010%5E%7B-7%7D%20m)
and
![c=3 \cdot 10^8 m/s](https://tex.z-dn.net/?f=c%3D3%20%5Ccdot%2010%5E8%20m%2Fs)
, we can find the value of the frequency:
Answer:
Leak 1 = 3.43 m/s
Leak 2 = 2.42 m/s
Explanation:
Given that the top of the boot is 0.3 m higher than the leaks.
Let height H = 0.3m and the acceleration due to gravity g = 9.8 m/s^2
From the figure, the angle of the leak 1 will be approximately equal to 45 degrees. While the leak two can be at 90 degrees.
Using the third equation of motion under gravity, we can calculate the velocity of leak 1 and 2
