How do objects become negatively charged using the contact method

Physics
1 answer:
Kamila [148]3 years ago
7 0

If a negative object is used to charge a neutral object, then both objects become charged negatively. In order for the neutral sphere to become negative, it must gain electrons from the negatively charged rod. A metal sphere is electrically neutral. It is touched by a positively charged metal rod.

Use the diagram to help answer these questions.
Arada [10]
The correct answers are as follows:
1. The wave with the larger frequency IS THE ONE AT THE TOP.
The frequency of a wave refers to the number of waves that is passing through a point in a certain time. The unit of frequency is Hertz. Looking at the diagrams above you will notice that the number of waves occurring per time in the top diagram is more that of the diagram below.

2. In the bottom wave, there are two complete wavelengths between 0 and 25 on the X axis.  The first wavelength starts from the point where one is written on the Y axis and end at the opposite end of 1, the second wavelength starts from that point and end at the location corresponding to the top of figure 25 on the X axis.

Why the formation of sand is a physical change.
Neko [114]
This is a physical change because there isn’t a change in composition of the substance, sand. It is only changing the shape, not having a chemical reaction of any sort.

A thin-walled vessel of volume V contains N particles which slowly leak out of a small hole of area A. No particles enter the vo
LuckyWell [14K]

Answer:

    \frac{V}{2av}

Explanation:

From the question we are told that

Volume V

Contains N particles

Leaks from a small hole of area A

Generally the equation for Flow rate is given as

Volume Flow Rate  V_r = A * v

Mathematically we find the  time taken to flow half way which is given by

          \frac{(V/2)}{A*v}

Therefore the  time taken is

           \frac{V}{2av}
