Explanation:
The biggest reason is radioactive wastes. Nuclear power generated radioactive wastes like Uranimum, plutonium and amercium that inhibits gene expression and causes cancer to the environment. Nuclear plants use to release these wastes into the oceans, and it causes fishes to exhibit gender change, 3 eyes, 2 tails etc. The impact on human shows signs of serious blood, liver and lung cancers.
There are currently no way to get rid of these wastes as they take hundred thousands of years to decompose.
Another reason is they cause a small amount of green gas emission. Releases CO2 to the sky. They exhibit radioactive gas emission as well (causes cancer) .
Answer: The frequency of this light is 
.
Explanation:-
To calculate the frequency of light, we use the equation:
where,
= wavelength of the light =
c = speed of light = 
= frequency of light = ?
The frequency of this light is .
Answer:
E to F
Explanation:
We know that v = dx/dt
and a = d²x/dt²
Decreasing velocity means deceleration or negative acceleration,
therefore d²x/dt²<0
i.e the portion where the graph is having its curvature downwards like an inverted u, from graph E to F portion looks like that.
Therefore in the portion E to F velocity decreases.
