Animals will then have to adapt to their new environment. they might have to change their diet and get new homes.
The complete question was calculate the period T assuming the smallest amplitude.
Using the equation;
T = 2 π√(L/g)
Where T is the period in seconds, L is the length of the rod or wire in meters and g is the acceleration due to gravity.
Hence; T = 2×3.14 × √(2/9.81)
= 6.28 × 0.4515
= 2.836 seconds
Answer:
vf = 22.36[m/s]
Explanation:
First we must understand the data given in the problem:
m = mass = 800 [kg]
F = force = 20000[N]
dx = displacement = 10[m]
From newton's second we know that the sum of forces must be equal to the product of mass by acceleration.
![F = m*a\\20000 = 800*a\\a = 20000/800\\a = 25 [m/s^2]](https://tex.z-dn.net/?f=F%20%3D%20m%2Aa%5C%5C20000%20%3D%20800%2Aa%5C%5Ca%20%3D%2020000%2F800%5C%5Ca%20%3D%2025%20%5Bm%2Fs%5E2%5D)
With the calculated acceleration, we can use the kinematics equations.
![v_{f} ^{2} =v_{o} ^{2}+2*a*dx\\ v_{o} = initial velocity = 0\\a = acceleration = 25[m/s^2]\\dx= displacement = 10[m]\\](https://tex.z-dn.net/?f=v_%7Bf%7D%20%5E%7B2%7D%20%3Dv_%7Bo%7D%20%5E%7B2%7D%2B2%2Aa%2Adx%5C%5C%20v_%7Bo%7D%20%3D%20initial%20velocity%20%3D%200%5C%5Ca%20%3D%20acceleration%20%3D%2025%5Bm%2Fs%5E2%5D%5C%5Cdx%3D%20displacement%20%3D%2010%5Bm%5D%5C%5C)
The key to using this equation is to clarify that the initial velocity is zero since the body is at rest, otherwise the initial velocity would be an initial data.
![v_{f} =\sqrt{2*25*10} \\v_{f} =22.36[m/s]](https://tex.z-dn.net/?f=v_%7Bf%7D%20%3D%5Csqrt%7B2%2A25%2A10%7D%20%5C%5Cv_%7Bf%7D%20%3D22.36%5Bm%2Fs%5D)
Another way of solving this problem is by means of the definition of work and kinetic energy, where work is defined as the product of the force by the distance.
W =F*d
W = 20000*10
W = 200000[J]
Kinetic energy is equal to work, therefore the value calculated above is equal to:
![E_{k}=W =0.5*m*v_{f}^{2} \\200000=0.5*800*v_{f}^{2}\\v_{f}=\sqrt{\frac{200000}{0.5*800} } \\v_{f}=22.36[m/s]](https://tex.z-dn.net/?f=E_%7Bk%7D%3DW%20%3D0.5%2Am%2Av_%7Bf%7D%5E%7B2%7D%20%5C%5C200000%3D0.5%2A800%2Av_%7Bf%7D%5E%7B2%7D%5C%5Cv_%7Bf%7D%3D%5Csqrt%7B%5Cfrac%7B200000%7D%7B0.5%2A800%7D%20%7D%20%5C%5Cv_%7Bf%7D%3D22.36%5Bm%2Fs%5D)
Answer: you are the person in charge of building a nuclear power plant in Florida. your first choice is to select a site for building the power plant.
Explanation: To find the answer, we need to know more about the nuclear power plants and the criteria to select the site for power plant.
<h3>
What you mean by nuclear power plants?</h3>
- Nuclear power can be defined from the nuclear fission reaction.
- These power plants will heat the water to produce steam and this steam is used to spin large turbines and thus generates electricity.
<h3>How to select the site for nuclear power plant?</h3>
- We have to consider the following things,
- keep distance from populated area.
- distance from load center.
- Accessibility to site.
- Water availability and fuel availability.
- waste disposal.
Thus, we can conclude that, before building a nuclear power plant, our first choice should be to select a site.
