The atomic mass of an element is defined as the weighted average mass of that element’s

Physics

marishachu [46]4 years ago

Answer:

False

Explanation:

Atomic mass (Also called Atomic Weight, although this denomination is incorrect, since the mass is property of the body and the weight depends on the gravity) Mass of an atom corresponding to a certain chemical element). The uma (u) is usually used as a unit of measure. Where u.m.a are acronyms that mean "unit of atomic mass". This unit is also usually called Dalton (Da) in honor of the English chemist John Dalton.

It is equivalent to one twelfth of the mass of the nucleus of the most abundant isotope of carbon, carbon-12. It corresponds roughly to the mass of a proton (or a hydrogen atom). It is abbreviated as "uma", although it can also be found by its English acronym "amu" (Atomic Mass Unit). However, the recommended symbol is simply "u".

<u> The atomic masses of the chemical elements are usually calculated with the weighted average of the masses of the different isotopes of each element taking into account the relative abundance of each of them</u>, which explains the non-correspondence between the atomic mass in umas, of an element, and the number of nucleons that harbors the nucleus of its most common isotope.

Looking at systems is important in science because
Vikentia [17]

Answer:

systems help identify parts and simplify solutions.

Explanation:

Systems are very important in science because they are made up of many parts and can help simplify solutions better.

A system is made up of several parts that are interacting together as a whole. They are very important in solving scientific problems and looking introspectively into a problem.

The parts that makes up the system are equally important as the whole. Systems are typified by what transpires at the level of their parts. Viewing a problem from a system wide angle helps scientists have better knowledge and can be vital in solving scientific problems.

A nonmechanical water meter could utilize the Hall effect by applying a magnetic field across a metal pipe and measuring the Hal
Serga [27]

Answer:

The velocity is  v =2.455 \  m/s

Explanation:

From the question we are told that  

   The diameter of the pipe is  d =  4.25 \ cm  = 0.0425 \ m

    The magnetic field is  B  =  0.575 \  T

     The hall voltage is  V_H =  60.0 mV  =  60 *10^{-3} \  V

Generally the average fluid velocity is mathematically represented as

          v = \frac{V}{ B  *  d }

=>       v = \frac{60*10^{-3}}{ 0.575   *  0.0425  }

=>       v =2.455 \  m/s

Answer:

Option A

Measures light from distant objects

Explanation:

A spectroscope is used to measure the use of light from a distant object to work out the object is made of.

It could be the single-most powerful tool astronomers use.

Professor Fred Watson from the Australian Astronomical Observatory says that "It lets you see the chemicals being absorbed or emitted by the light source"
