The magnitude of electric field is produced by the electrons at a certain distance.
E = kQ/r²
where:
E = electric field produced
Q = charge
r = distance
k = Coulomb Law constant 9 x10^9<span> N. m</span>2<span> / C</span><span>2
Given are the following:
Q = </span><span>1.602 × 10^–19 C
</span><span>r = 38 x 10^-9 m
Substitue the given:
E = </span>
E = 998.476 kN/C
Answer:

Explanation:
The period of a simple pendulum is given by:

where
L is the length of the pendulum
g is the acceleration of gravity
From this equation we can write

Taking the square of this equation, we get:

So we see that
is proportional to L and inversely proportional to g. So, we can write:

So the only correct option is

For the first one, trees are organisms, so it’s B.
The second one,, the heavy percolation and strong winds come from hurricanes. So it’s hurricanes
Ok I don’t know the answer I’m in 5th grade but 2431 is wrong
Answer:
“A mountain of uranium” is an indefinable amount of uranium. If it means uranium ore as found in nature, then the concentration of uranium is orders of magnitude too low for any type of reaction.
