Answer:
For anyone who needs this answer in the future the answer is "The government agency responsible for monitoring water safety"
Explanation:
I took the quiz and got it right! It is that answer because the people who's profession is monitoring water safety would be the most reliable to ask this question. Hope this helps.
<span>We can use the equation for the force of gravity to solve this question.
F = G M1 M2 / R^2
Let R be the radius of the planet.
f0 = G M1 M2 / (2R)^2
f0 = (1/4) x (G M1 M2 / R^2)
We can find an expression for f2.
f2 = G M1 M2 / (4R)^2
f2 = (1/16) x (G M1 M2 / R^2)
We can express f2 in terms of f0:
f2 = (4/16) x f0
f2 = 0.25 f0</span>
Answer:
a) FE = 0.764FG
b) a = 2.30 m/s^2
Explanation:
a) To compare the gravitational and electric force over the particle you calculate the following ratio:
(1)
FE: electric force
FG: gravitational force
q: charge of the particle = 1.6*10^-19 C
g: gravitational acceleration = 9.8 m/s^2
E: electric field = 103N/C
m: mass of the particle = 2.2*10^-15 g = 2.2*10^-18 kg
You replace the values of all parameters in the equation (1):

Then, the gravitational force is 0.764 times the electric force on the particle
b)
The acceleration of the particle is obtained by using the second Newton law:

you replace the values of all variables:

hence, the acceleration of the particle is 2.30m/s^2, the minus sign means that the particle moves downward.
Gravity..? I don't know, but you need to clear up your question a bit. I'm sure it's gravity though.
It’ll be 200 meters West because 500-300=200 and The west direction has the greatest force you could say ... Anytime you have a question asking about displacement you subtract then use the direction with the greatest number ..
