Answer:Thus, if each of the charges were reduced by one-half, the repulsion would be reduced to one-quarter of its former value. Also In electrostatics, the electrical force between two charged objects is inversely related to the distance of separation between the two objects. ... And decreasing the separation distance between objects increases the force of attraction or repulsion between the objects.
Hope this helps have a awesome night/day❤️✨
Explanation:
Nothing, until those two objects physically touch each other; contact aligns polarity among the now single shared mass.
(Your question never states if both objects are unique or similar polar charges, so I just assumed they were both neutral objects existing within an electric field.)
So a better question would then be, what is gravity’s relationship with an electric field?
You could solve this with the following: confine the electric field’s volume to a set variable (never increasing nor decreasing in size or shape); density is variable and easily definable. This creates the limit to build upon. This density has to be fluid and has electron mass (full of electrons at rest mass, so with substance but no movement). Within, create a closed system (the hard part in this equation; outside interference like ambient light will eschew results) where each variable of kinetic energy then is accounted for or measurable (including heat and light, and the physical movement of the two objects)
Determine the mass for both objects, calculate gravity for both and each body’s inertia on the other as a sum over distance. record results. Polarity is shared across the masses until there is no longer inertia (one mass or contact).
i dont understand ..............
Take the upward and to-the-right directions to be positive (so down and to-the-left are negative).
The vertical forces acting on the object cancel, 6 N - 6 N = 0.
The horizontal forces exert a net force of 20 N - 3 N = 17 N. This net force is positive, so it points to the right. So the answer is A.
Solids, liquids, and gases are very often depicted as groups of particles inside containers of fixed shape and dimension.

A
The physical properties of this phase of matter are that the particles take the shape of the container, do not fill the entire volume, and are very strongly attracted to each other.
B
The physical properties of this phase of matter are that the particles take the shape of the container, do not fill the entire volume, and are strongly attracted to each other.
C
The physical properties of this phase of matter are that the particles take the shape of the container, they fill the entire volume of the container, and are strongly attracted to each other.
D
The physical properties of this phase of matter are that the particles do not take the shape of the container, they fill the entire volume, and are weakly attracted to each other.

what physical properties dose plutonium
Answer:
Explanation:
Plutonium-239 is one of the two fissile materials used for the production of nuclear weapons and in some nuclear reactors as a source of energy. The other fissile material is uranium-235. Plutonium-239 is virtually nonexistent in nature. It is made by bombarding uranium-238 with neutrons in a nuclear reactor. Uranium-238 is present in quantity in most reactor fuel; hence plutonium-239 is continuously made in these reactors. Since plutonium-239 can itself be split by neutrons to release energy, plutonium-239 provides a portion of the energy generation in a nuclear reactor.

how can understanding velocity help to prevent a mid-air collision
Answer:
To maintain enough time to prevent a collision, a system operating in air traffic where aircraft speed does not
fall below 100 km/h (most medium-sized UAVs and GA aircraft) will need to be able to detect obstacles which
subtend an arc-width of as small as 0.125 mra

8. How do you know that
the bicyclists in the first
panel above are moving
at a constant velocity?
Answer:
Constant velocity means that the object in motion is moving in a straight line at a constant speed. You know this as in the first panel each arrow representing each second is the same width apart, therefore you know the cyclists are moving at a constant velocity. Compare this to the second box representing changing speed. The arrows are different lengths meaning each second the cyclists are moving at a different speed and are not moving at a constant velocity.

Explanation:
What is the total energy of a system with KE = 1368 J and a PE = 5782J? Express your answer in kJ.
Answer:
7.150 KJ
Explanation:
The total energy of a system is the sum of the potential and kinetic energy in the system. According to this question, the kinetic energy (KE) = 1368 J and a potential energy (PE) = 5782J.
Total energy of the system will be PE + KE as follows;
1368J + 5782J
= 7150J
However, the question demanded that the answer be in kJ (kilojoules), which is higher than the joules.
Since 1kJ = 1000J
7150J = 7150/1000
= 7.150kJ
Please help, it’s the last question and I’m bad at Physics
Answer:
The end velocity of the sculpture is 7.00 m/s²
Explanation
The equation needed here is v = √(2gh). Let's do it:
v = √(2 × 9.8m/s² × 2.5m)
v = √(49.0 m²/s²)
v = 7.0m/s
Funny enough the numbers given don't have the accuracy demanded. We're given is 2.5m which is only accurate to the tenths, and 30kg which is only accurate to the nearest integer. Also, presumably the acceleration due to Earth gravity that's provided is only 9.8m/s², so that's still only the nearest tenth. So taking those and asking to find the answer to the nearest hundredth is pointless.
But whatever. The given answer is correct to the nearest hundredth. 7.00m/s² To be sure, I plugged it into a form on a physics page that does exactly that, and the answer they gave was 7.0023745972349, so we have it rounded correctly.
