Answer:
The ban was intended to prevent the imminent extinction of ospreys, peregrine falcons, and bald eagles, our national bird, among other species; they were vulnerable because DDT caused a fatal thinning of eggshells, which collapsed under the weight of the parent incubating them.
Explanation:
The hidden cost was to control pests was washing off into rivers and streams, poisoning fish, birds, and even humans with toxic chemicals.
Hope this helps
Answer:
Positive z-direction
Explanation:
According to Fleming's right hand rule, point the fingers of your right hand in the direction of Electric field E ( positive x-direction), and curl your fingers toward magnetic field B (positive y-direction), and your thumb points in the direction of propagation of wave (positive z-direction).
Therefore, the correct option will be positive z-direction.
Answer:
C) specific heat capacity
Explanation:
As we know that heat given to the system to change the temperature is given as
here we know that
Q = thermal energy given to the system
s = specific heat capacity of the system
= change in temperature
so here we know that
here we know that heat given to the two cubes is of same amount as well as the mass is same but the final temperature is different because of the specific heat capacity (s)
So correct answer would be
C) specific heat capacity
Answer:
In metallic bonds, the valence electrons from the s and p orbitals of the interacting metal atoms delocalize.
On the left, you have
while on the right, you have
To get a balanced equation, you'll need 6 KBr on the right, which would require 2 AlBr3 and 3 K2SO4 on the left, so you end up with
