vesna_86 [32]

Answer:True

Explanation: External factors are factors outside of an organisation or an institution that has the capacity of either adversely or positively affect the institution or the Organisation.

For an institution to prosper and perform optimally in an economy.or a country, such Institution must put into cognisance the possible external threats that are capable of affecting it, when Organisations or Institution put strategies in place to control or mitigate such externalities,the institution or Organisation will sure Prosper.

Final naïve case: If the highest-pitch string on the piano is made of spring steel (density = 7800 kg/m3) with a diameter of 1/3
oksano4ka [1.4K]

Answer:

The linear density is  K  =  3.863 *10^{-3 } \  kg/m

Explanation:

From the question we are told that

     The density of  steel is  \rho =  7800 \  kg/m^3

      The diameter of the string is  d = 0.794 \ mm =  7.94 *10^{-4} \ m

       The  radius of  the string is  evaluated as  r =  \frac{D}{2}  =  \frac{7.94 *10^{-4}}{2} = 3.97*10^{-4} \ m

The volume of the string is  mathematically evaluated as

       V  = \pi * r ^2 *  L

Now assuming that the length of the string is  L = 2 m  

      So  

         V  =  3.142 *  (3.97 *10^{-4})^2 * (2)

        V  = 9.9041 *10^{-7} \ m^3

Then the mass of the string would be  

       m  = \rho *  V

substituting value  

       m  =  7800*9.904 14 *10^{-7}

      m  =  7.73*10^{-3} \ kg

Looking at the question we see that the unit of the linear density is  \frac{kg}{m}

Hence the linear density is evaluated as

        K  =  \frac{m}{L}

substituting value  

        K  =  \frac{7.73 *10^{-3}}{2}

        K  =  3.863 *10^{-3 } \  kg/m

Define the unit of current. Name the device which is used to measure
Free_Kalibri [48]

Answer:

The ampere, symbol A, is the SI unit of electric current. It is defined by taking the fixed numerical value of the elementary charge e to be 1.602 176 634 x 10-19 when expressed in the unit C, which is equal to A s, where the second is defined in terms of ΔνCs.

the device used to measure current in a circuit is ammeter
