Sand dunes refers to accumulation of sand grains, which is shaped into a mound by the wind. Sand dunes are first line of protection against coastal storm and beach erosion. Sand dunes destruction can be caused by many factors, but the most prominent factor is human activity. The sand dunes can be preserve and saved by planting beach grasses, erecting sand fencing, erecting and using public crossovers, keeping boats off from the sand dunes and desisting from the act of burning beach grasses.<span />

vredina [299]

A car is built from various subsystems. If these subsystems are not working properly it is dangerous because it can cause a serious traffic accident.

<h3>What subsystems do cars have?</h3>

When you're testing the build of a car, you have to check its many subsystems:

  • the battery
  • the engine
  • the cabin
  • the thermal-management system
  • the gearbox
  • the chassis
  • the suspension

<h3>Why is a car with damaged subsystems dangerous?</h3>

The subsystems of a car are very important components that allow the proper functioning of the car. These subsystems work synchronously making the car work properly.

However, if one of these subsystems is not working properly it could cause a malfunction that could lead to a traffic accident.

Letícia leaves the grocery store and walks 150.0 m to the parking lot. Then, she turns 90° to the right and walks an additional
Alexxx [7]

Answer:

165.529454

Explanation:

According to the Pythagorean Theorem for calculating the lengths of a right angle triangle's sides, a^2 + b+2 = c^2, where c is the longest side (and the side opposing the right angle). So in your case it would be 150*150 + 70*70 = 27400. And √ 27400 is your answer.

An injured monkey sits perched on a tree branch 9 m above the ground, while a wildlife veterinarian is kneeling down in the bush
Yakvenalex [24]

Answer:

The hunter should aim directly at the perched monkey because the tranquilizer dart will fall away from the line sight at the same rate that the monkey falls from its perch.

Tan theta = 9 / 90 = .1      so theta = 5.71 deg

The time for the monkey to reach the ground is

t = (2 h / g)^1/2 = (18 / 9.8)^1/2 = 1.36 sec

So the horizontal speed of the dart must be at least

Vx = 90 m / 1.36 sec = 66.4 m/s

Vx = V cos theta

V = 66.4 m/s / cos 5.71 = 66.7 m/s
