The electrostatic force between two charged objects is given by

where
k is the Coulomb's constant
q1 is the charge of the first object
q2 is the charge of the second object
r is the separation between the two objects
In our problem:



So if we plug these numbers into the equation, we can find the electrostatic force between the two objects:
The distance is just the perimeter of the rectangle:
P = 2(411) + 2(475)
P = 822 + 950
P = 1772m
Answer: B
Baking soda has unique properties. It can be used in multiple ways, like cleaning. Productive means something produces a lot of something. Baking soda does not produce anything. Baking soda does not have distinguishable properties, other things can substitute baking soda.
Hope this answer helps you!
De-celleration because speed is lower as time goes on
Answer:
g = 5 m/s square
Explanation:
Weight(W), Mass(m), Gravity(g)
W = mg
1,000N = 200g
g = 1000/200
g = 5 m/s square
