Complete Question

The complete question is shown on the first uploaded image

Answer:

Explanation:

From the question we are told that

    The tension is  T  =  440 \  N

     The length of the wire is l =  0.600 \  m

     The mass is  m  =  5.60 \ g = 0.0056 \  kg

Generally the frequency is mathematically represented as

            f  =  \frac{1}{2l}  *  \sqrt{\frac{T}{\frac{m}{l} } }

=>        f  =  \frac{1}{2 * 0.600 }  *  \sqrt{\frac{440}{\frac{0.0056}{0.600} } }

=>        f = 181 \ Hz

What are the names of the 2 charged particles in an atom and what are their charges
Sholpan [36]

Answer:

Protons and electrons

Explanation:

  • The atoms are made up of protons, neutrons, and electrons.
  • The physical and chemical characteristics of an atom are determined by the number of these particle composition.
  • The protons present in the center of an atom called the nucleus is positively charged.
  • The neutrons are also located in the nucleus of an atom with no charge.
  • The electrons has a negative charge and it is placed around the nucleus having different shells and quantum state.
  • The charges of the protons and electrons are denoted by +q and -q. The quantization of these charges are +1, +2, ... and -1, -2, .... etc.

What happens to air pressure as altitude decreases
Ksivusya [100]
Pressure decreases with increasing altitude. The pressure at any level in the atmosphere may be interpreted as the total weight of the air above a unit area at any elevation. At higher elevations, there are fewer air molecules above a given surface than a similar surface at lower levels.
