Increases untill the distance becomes greater than the force of Attraction..
Answer:
105 mg
Explanation:
The following data were obtained from the question:
Original amount (N₀) = 420 mg
Half life (t½) =20 days
Time (t) = 40 days
Amount remaining (N) =..?
Next, we shall determine the rate constant K, for the disintegration.
This can be obtained as follow:
Half life (t½) =20 days
Rate constant (K) =?
K = 0.693/ t½
K = 0.693/20
K = 0.03465 /day
Finally, we shall determine the amount remaining after 40 days as follow:
Original amount (N₀) = 420 mg
Rate constant (K) = 0.03465 /day
Time (t) = 40 days
Amount remaining (N) =..?
Log(N₀/N) = kt/2.3
Log (420/N) = (0.03465 x 40)/2.3
Log (420/N) = 1.386/2.3
Log (420/N) = 0.6026
420/N = antilog (0.6026)
420/N = 4
Cross multiply
420 = N x 4
Divide both side by 4
N = 420/4
N = 105 mg
Therefore, the amount remaining after 40 days is 105 mg.
The gas cylinder only contains pure ammonia and so it is a pure chemical substance and a compound.
What is a compound?
compound refers to a chemical substance that is made up of several similar molecules containing elements from multiple elements. Most noteworthy, the bounding of these molecules takes place by chemical bonds. A chemical formula gives an indication of the number of atoms of each element existing in a compound molecule.

Answer:
Possible options are:
A. It will move toward the large ball because like charges repel.
B. It will move toward the large ball because like charges attract.
C. it will move away from the large ball because like charges repel.
D. it will move away from the large ball because like charges attract.
Answer: C. it will move away from the large ball because like charges repel.
Explanation:
All things are made up of charges. Opposite charges attract each other (negative to positive). Like charges repel each other (positive to positive or negative to negative). Most of the time positive and negative charges are balanced in an object, which makes that object neutral.
Static electricity is the result of an imbalance between negative and positive charges in an object. These charges can build up on the surface of an object until they find a way to be released or discharged. One way to discharge them is through a circuit.
In The RGB color model, colors are described in numerical codes which are written in brackets and separated by commas.
<h3>What is RGB model ?</h3>
RGB model is a color ( additive ) which enables the addition of RED, Green and Blue colors which are the primary colors of light in various ways to produce different colors.
In RGB model the RGB values gets to display different colors when used on different devices hence it can not be described as a reference point for RED, Green and Blue colors.
Hence we can conclude that In The RGB color model, colors are described in numerical codes which are written in brackets and separated by commas.
