How many neutrons does element X have if its atomic number is 48 and its mass number is 167?

Physics

Llana [10]3 years ago
8 0
If its atomic number is 48, then it has 48 protons in the nucleus
of each atom.  Any more mass than that is supplied by the neutrons
that are mixed in there with the protons.

If the mass is 167, and 48 of those are protons, then there are

             (167 - 48)  =  119 neutrons

in each nucleus.

Answer:

Magnitude is 144N .

Explanation:

a²+b²=c²

120N²+80N²=c²

14400+6400=c²

\sqrt{20800}   =  \sqrt{c} ^{2}

  • Length=l=4m

\\ \rm\rightarrowtail T=2\pi\sqrt{\dfrac{l}{g}}

\\ \rm\rightarrowtail T=2\pi\sqrt{\dfrac{4}{9.8}}

\\ \rm\rightarrowtail T=2\pi(0.63887)

\\ \rm\rightarrowtail T=1.27774\pi

\\ \rm\rightarrowtail T=4.012s

How is power defined? Question 4 options: the quantity of work accomplished the direction of the work the total distance an obje
GarryVolchara [31]

Power can be defined as the rate at which work is accomplished.

Option D is the correct answer.

<h3></h3><h3>Power </h3>

The work done by an object in a given time interval is called the power of that object.

Suppose an external force F is applied to any object for the time interval T seconds. Due to this external force, the object will perform some amount of work for the time T seconds. This work W done by the object for the time interval T seconds is called the power of that object.

Power can be defined in mathematical term which is given below.

P = \dfrac {W}{T} \;\rm Watts

Thus the power can also be defined as the work done by the object per unit time interval.

Hence we can conclude that option D is the correct answer.

To know more about power, follow the link given below.
