Mine tailings be stored and disposed of carefully since they
contain a lot of chemicals that are very toxic that leaches into aquifers, and
they also runoff in the rainwater into streams and lakes.
Tailings, also
called mine <span>dumps, culm dumps, slimes, tails, refuse,
leach residue or slickens, are the materials left over after the process of
separating the valuable fraction from the uneconomic fraction (gangue) of an
ore.</span>
Answer:
the pearls have an electrical charge induced by contact with the ions of the solution and these charges are attracted by the electrode by a force electric
Explanation:
The pearls are suspended in a solution, when connecting the power source, it is subjected to an electric shock, the pearls have an electrical charge induced by contact with the ions of the solution and these charges are attracted by the electrode by a force electric

Answer:
a) The trajectory will be a helical path.
b) θ = 2*π rad
Explanation:
a) Since the initial velocity of the particle has a component parallel (x-component) to the magnetic field B
, the trajectory will be a helical path.
b) Given
t = 2*π*m/(q*B)
We can use the equation
θ = ω*Δt
where
θ is the angular displacement
ω is the angular speed, which is obtained as follows:
ω = q*B/m
then we have
θ = (q*B/m)*2*π*m/(q*B)
⇒ θ = 2*π rad
