2 disadvantages would be damage to Marine life and hydroelectric plants are very expensive.If they plant is not stable and breaks it can cause flash floods and property damage.2 advantages would be that they do not emit any carbon emmissions.Some cities cannot build hydroelectric power plants because  the stream does not have that kind of pressure .so really it matters greatly on where the dam would be placed. but sunny places like arizonasolar plant would be great


I hope this help

An object is dropped on Earth from a height of 15 m. What is the magnitude of the velocity of the object just as it hits the gro
ivolga24 [154]
Here, we know, according to 3rd Equation of Kinematics, 
v² - u² = 2as

Here, u = 0  [ Free fall ]
a = 9.8 m/s² [ constant value for the Earth system ]
s = 15 m

Substitute their values, 
v² - 0² = 2 * 9.8 * 15
v² = 294
v = √294
v = 17.15 m/s

In short, Your Answer would be Option D

Hope this helps!

lions [1.4K]

Answer:

The speed of the 1 kg red ball 8.04 m/s .

Explanation:

Given :

Separation between rods , d = 1.5 m .

Mass of the red ball is 1 kg .

Mass of the orange ball is 5.7 kg .

Angular velocity , \omega=1\ rev/s = 2\pi\ rad/s .

Now , distance of center of mass  from red ball is :

r =\dfrac{0\times 1+1.5\times 5.7}{1+5.7}\\\\r = 1.28\ m

We know , speed is given by :

v=\omega r\\\\v=2 \times \pi \times  1.28\\\\v=8.04\ m/s

Hence , this is the required solution .
