Answer:
i) 0.9504
ii) 0.0452
Explanation:
Given data: reliability of hydraulic brakes= 0.96
reliability of mechanical brakes = 0.99
So the probability of stopping the truck = 0.96×0.99= 0.9504
At low speed
case: A works and B does not
= 0.96×(1-0.99) = 0.0096
case2 : B works and A does not
= 0.99×(1-0.96) = 0.0396
Therefore, probality of stopping = 0.0096+0.0396 = 0.0492
Answer:
Sediments can be carried from one place to another. The movement of sediments by wind, water, ice, or gravity is called erosion.
Answer:
Water falls from a reservoir through a channel to a turbine. The water turns the turbines, which allows the generator to make electricity.
It is falling instead of flowing, because elavation is an important part of the hydroeletric power plant, since gravity is a thing, and there was elevation, than it would be falling and not flowing.
The acceleration of the particle at 3s is [tex]a = 6 \beta [/tex]
![v = \alpha + \beta {t}^{2}](https://tex.z-dn.net/?f=v%20%20%3D%20%20%5Calpha%20%20%2B%20%20%5Cbeta%20%7Bt%7D%5E%7B2%7D%20)
<h3>How to calculate acceleration </h3>
![a = \frac{dv}{dt} \\ v = \alpha + \beta {t}^{2} \\ \frac{dv}{dt} = 0 + 2 \beta t \\](https://tex.z-dn.net/?f=a%20%3D%20%20%5Cfrac%7Bdv%7D%7Bdt%7D%20%5C%5C%20v%20%3D%20%20%5Calpha%20%20%2B%20%20%5Cbeta%20%20%7Bt%7D%5E%7B2%7D%20%5C%5C%20%5Cfrac%7Bdv%7D%7Bdt%7D%20%20%3D%200%20%2B%202%20%5Cbeta%20t%20%5C%5C%20)
if Time is given as 3s
therefore, Acceleration is
![a = 2 \beta t \\ a = 2 \beta 3 \\ a = 2 \times \beta \times 3 \\ a = 6 \beta](https://tex.z-dn.net/?f=a%20%3D%202%20%5Cbeta%20t%20%5C%5C%20a%20%3D%202%20%5Cbeta%203%20%5C%5C%20a%20%3D%202%20%5Ctimes%20%20%5Cbeta%20%20%5Ctimes%203%20%5C%5C%20a%20%3D%206%20%5Cbeta%20)
Acceleration is
![a = 6 \beta](https://tex.z-dn.net/?f=a%20%3D%206%20%5Cbeta%20)
