A T.V. tower has a height of 100 m. How much population is covered by T.V. broadcast, if the average population density around the tower is 1000 / km2 ?
Correct answer: A. 39.5 x 10^5
- A. 39.5 x 10^5
- B. 19.5 x 10^6
- C. 29.5 x 10^7
- D. 9 x 10^4
Explanation
This is the following solution:Radius of the area covered by T.V.telecastd=√2hRe Total population covered=πpd2×population density= 2πhRe × population density =2×3.14×100×6.4×10⁶×(1000/10⁶)=39.503×10⁵

About Alternating Current
Alternating current varies periodically, so phase relationships become essential when current passes through a resistor, capacitor or inductor. The chapter distinguishes resistance from capacitive and inductive reactance, explains phase lead and lag, and connects changing electric and magnetic fields with the production and properties of electromagnetic waves.
