Out of all given choices, “Different samples have different properties” is not a characteristic of a compound

Answer: Option A

<u>Explanation: </u>

A substance which comprises of more than one element chemically linked together at a fixed weight ratio usually referred as compound. The relationship arises due to the result of the chemical reactions between the components of the elements.

The property of the compound vary from the property of its elements to which it gets formed. For example: Water (H_{2} O) is a combination of two elements, hydrogen and oxygen, chemically bonded in a constant 1: 8 weight ratio .

Two charged particles are a distance of 1.62 m from each other. One of the particles has a charge of 7.10 nc, and the other has
k0ka [10]

Answer:

A. F=107.6nN

B. Repulsive

Explanation:

According to coulombs law, the force between two charges is express as

F=(Kq1q2) /r^2

If the charges are of similar charge the force will be repulsive and if they are dislike charges, force will be attractive.

Note the constant K has a value 9*10^9

Hence for a charge q1=7.10nC=7.10*10^-9, q2=4.42*10^-9 and the distance r=1.62m

If we substitute values we have

F=[(9×10^9) ×(7.10×10^-9) ×(4.42×10^-9)] /(1.62^2)

F=(282.4×10^-9)/2.6244

F=107.6×10^-9N

F=107.6nN

B. Since the charges are both positive, the force is repulsive
