rocks

Explanation:Google

Most of Earth's carbon—about 65,500 billion metric tons—is stored in rocks. The rest is in the ocean, atmosphere, plants, soil, and fossil fuels. Carbon flows between each reservoir in an exchange called the carbon cycle, which has slow and fast components.

Calculate the electric field (in V/m) between two parallel plates connected to a 45 V battery if the plates are separated by a)

Sonja [21]

Answer:

Explanation:

Given

Voltage of battery $V=45\ V$

electric field(E) is given by

$E=|-\frac{dV}{dx}|$

i.e. Change in Potential over a distance x

(a)When Plate are separated by 3 cm apart

$E=|\frac{45}{3\times 10^{-2}}|$

$E=1500\ V/m$

(b)When Plates are 5 cm apart

$E=|-\frac{45}{5\times 10^{-2}}|$

$E=900\ V/m$

Force on electron is given by

$F=charge\times Electric\ Field$

$F=q\times E$

For case a

$F=1.6\times 10^{-19}\times 1500$

$F=24\times 10^{-17}\ N$

(b) $F=1.6\times 10^{-19}\times 900=14.4\times 10^{-17}\ N$

An unfortunate 18 kg monkey falls from a 40 m tall tree. What is the monkeys final velocity just befor he impacts the ground.? a

zalisa [80]

The correct answer is c) 28 m/s.
Let's find the step-by-step solution. The motion of the monkey is an uniformly accelerated motion, with acceleration equal to $g=9.81 m/s^2$ . The initial velocity of the monkey is zero, while the distance covered is S=40 m. Therefore, we can use the following relationship to find vf, the final velocity of the monkey:
$2aS=v_f^2-v_i^2=v_f^2$
from which
$v_f= \sqrt{2aS}= \sqrt{2\cdot 9.81 m/s^2 \cdot 40 m}=28 m/s$

Write a speech about bringing back fidget toys because they're banned in school

12345 [234]

I believe that fidget toys should not be brought back in school, reason being is because fidget spinners were originally made for students with example: Autism . Who actually needed them. Now that people who don't need them are buying them and playing with them in the classroom, it causes a complete distraction and is not being used for its original purpose whatsoever .
