Question:
What is a disadvantage of using nuclear power to produce electricity?
Answer:
Disadvantages of Nuclear Power
The further implementations of nuclear power are limited because although nuclear energy does not produce CO2 the way fossil fuels do, there is still a toxic byproduct produced from uranium-fueled nuclear cycles: radioactive fission waste.
Answer:
<em>the ball travels a distance of 8.84 m</em>
Explanation:
Range: Range is defined as the horizontal distance from the point of projection to the point where the projectile hits the projection plane again.
R = (U²sin2∅)/g.............................. Equation 1
Where R = range, U = initial velocity, ∅ = angle of projection, g = acceleration due to gravity.
<em>Given: U = 10 m/s, ∅ = 60°</em>
<em>Constant: g = 9.8 m/s²</em>
Substituting these values into equation 1
R = [10²×sin(2×60)]/9.8
R = (100sin120)/9.8
R = 100×0.8660/9.8
R = 86.60/9.8
R = 8.84 m
<em>Therefore the ball travels a distance of 8.84 m</em>
Answer:
The average force exerted by the water on the ground is 17.53 N.
Explanation:
Given;
mass flow rate of the water, m' = 135 kg/min
height of fall of the water, h = 3.1 m
the time taken for the water to fall to the ground;
![h = ut + \frac{1}{2}gt^2\\\\h = 0 + \frac{1}{2}gt^2\\\\t = \sqrt{\frac{2\times 3.1}{9.8} } \\\\t = 0.795 \ s](https://tex.z-dn.net/?f=h%20%3D%20ut%20%2B%20%5Cfrac%7B1%7D%7B2%7Dgt%5E2%5C%5C%5C%5Ch%20%3D%200%20%2B%20%20%5Cfrac%7B1%7D%7B2%7Dgt%5E2%5C%5C%5C%5Ct%20%3D%20%5Csqrt%7B%5Cfrac%7B2%5Ctimes%203.1%7D%7B9.8%7D%20%7D%20%5C%5C%5C%5Ct%20%3D%200.795%20%5C%20s)
mass of the water;
![m = m't\\\\m = 135 \ \frac{kg}{min} \ \times \ 0.795 \ s \ \times \ \frac{1 \ \min}{60 \ s} \ = 1.789 \ kg](https://tex.z-dn.net/?f=m%20%3D%20m%27t%5C%5C%5C%5Cm%20%3D%20135%20%5C%20%5Cfrac%7Bkg%7D%7Bmin%7D%20%5C%20%5Ctimes%20%5C%200.795%20%5C%20s%20%5C%20%5Ctimes%20%5C%20%5Cfrac%7B1%20%5C%20%5Cmin%7D%7B60%20%5C%20s%7D%20%5C%20%3D%201.789%20%5C%20kg)
the average force exerted by the water on the ground;
F = mg
F = 1.789 x 9.8
F = 17.53 N
Therefore, the average force exerted by the water on the ground is 17.53 N.
