Answer:
230.4 N
Explanation:
Applying,
F = kqq'/r²..................... Equation 1
Where F = Electric force, k = Coulomb's constant, q = charge in the ballon, q' = charge in the denium, r = distance between the charges.
From the question,
Given: q = -8.0×10⁻⁶ C, q' = +8.0×10⁻⁶ C, r = 0.05 m
Constant: k = 9×10⁹ Nm²/C²
Substitute these values into equation 1
F = (9×10⁹×8.0×10⁻⁶×8.0×10⁻⁶ )/0.05²
F = (576×10⁻³)/0.0025
F = 230.4 N.
Answer:
A force that resists motion between two objects that are in contact; rubbing together of two objects = <em>Friction</em>
<em />
The tendency of an object to float = <em>Buoyancy</em>
<em />
A push or pull; any quantity that produces or is capable of producing motion = <em>Force</em>
<em />
A universal force that every mass exerts on every other mass; this keeps us down on earth = <em>Gravity</em>
<em />
A free body diagram is a diagram that labels all the forces acting on an object. This allows us to find the net force on an object = <em>Free body diagram</em> (it literally says it in the definition lol)

Answer: Liquefaction occurs when the structure of a loose, saturated sand breaks down due to some rapidly applied loading.
As the structure breaks down, the loosely-packed individual soil particles attempt to move into a denser configuration. Liquefaction most often occurs when three conditions are met:
loose, granular sediment or fill
saturation by groundwater
strong shaking
Newton's First Law: An object in motion stays in motion, an object at rest stays at rest unless an unbalanced force acts upon it. For example, when zipping down the zip line you will stay in motion unless an outside force interferes. ... The more mass the more force needed.
