Answer:
i)ω=3600 rad/s
ii)V=7059.44 m/s
iii)F=1245.8 N
Explanation:
i)
We know that angular speed given as
![\omega =\dfrac{d\theta}{dt}](https://tex.z-dn.net/?f=%5Comega%20%3D%5Cdfrac%7Bd%5Ctheta%7D%7Bdt%7D)
We know that for one revolution
θ=2π
Given that time t= 2 hr
So
ω=θ/t
ω=2π/2 = π rad/hr
ω=3600 rad/s
ii)
Average speed V
![V=\sqrt{\dfrac{GM}{R}}](https://tex.z-dn.net/?f=V%3D%5Csqrt%7B%5Cdfrac%7BGM%7D%7BR%7D%7D)
Where M is the mass of earth.
R is the distance
G is the constant.
Now by putting the values
![V=\sqrt{\dfrac{GM}{R}}](https://tex.z-dn.net/?f=V%3D%5Csqrt%7B%5Cdfrac%7BGM%7D%7BR%7D%7D)
![V=\sqrt{\dfrac{6.667\times 10^{-11}\times 5.98\times 10^{24}}{8000\times 10^3}}](https://tex.z-dn.net/?f=V%3D%5Csqrt%7B%5Cdfrac%7B6.667%5Ctimes%2010%5E%7B-11%7D%5Ctimes%205.98%5Ctimes%2010%5E%7B24%7D%7D%7B8000%5Ctimes%2010%5E3%7D%7D)
V=7059.44 m/s
iii)
We know that centripetal fore given as
![F=\dfrac{mV^2}{R}](https://tex.z-dn.net/?f=F%3D%5Cdfrac%7BmV%5E2%7D%7BR%7D)
Here given that m= 200 kg
R= 8000 km
so now by putting the values
![F=\dfrac{mV^2}{R}](https://tex.z-dn.net/?f=F%3D%5Cdfrac%7BmV%5E2%7D%7BR%7D)
![F=\dfrac{200\times 7059.44^2}{8000\times 10^3}](https://tex.z-dn.net/?f=F%3D%5Cdfrac%7B200%5Ctimes%207059.44%5E2%7D%7B8000%5Ctimes%2010%5E3%7D)
F=1245.8 N

Answer:
Architectural plans.
Explanation:
An architectural plan is called the drawings made by architects, civil engineers or designers of spaces or interiors, in which these professionals capture their building projects, organizing the distribution of the spaces to be used, the elements to be located in them and, fundamentally, to give construction planning a projection into reality. Thus, the plans help professionals to have a better understanding of the expected end result of the projects they are carrying out.
Answer:
to clear land for agriculture and settlement and to use or sell timber for lumber, paper products, or fuel.
Answer:
If a truss buckles or overturns, it is usually because of the failure of an adjacent truss or its bracing. A steel truss in a fire may buckle and overturn because of expansion or weakening from the heat. Most truss failures are the result of broken connections. Photo 1 shows a set of parallel-chord wood trusses supporting a plywood floor deck.
