Asatellite in geostationary orbit is used to transmit data via electromagnetic radiation. the satellite is at a height of 35,000 km above the surface of the earth, and we assume it has an isotropic power output of 1.0 kw (although, in practice, satellite antennas transmit signals that are less powerful but more directional). reception devices pick up the variation in the electric field vector of the electromagnetic wave sent out by the satellite. given the satellite specifications listed in the problem introduction, what is the amplitude e0 of the electric field vector of the satellite broadcast as measured at the surface of the earth? use ϵ0=8.85×10^−12c/(v⋅m) for the permittivity of space and c=3.00×10^8m/s for the speed of light.

Explanation:

P = Power Output = 1000 W

r = Radius = 35000000 m

= Permittivity of free space =

c = Speed of light =

Intensity of Electric radiation

Intensity of Electric radiation

The amplitude of the electric field vector is

  1.the balanced   chemical equation is as below

cu +   2 ag(no)₃ → cu(no₃)₂   +2 ag

2.the   much silver   produced   is   50.9 g

step 1: find the   moles of cu

moles =   mass÷   molar mass

  from periodic table the molar mass of cu = 63.5 g/mol

moles is therefore = 15.00 g÷ 63.5 g/mol = 0.236   moles

step 2: use the mole ratio to determine the   moles of ag

from equation above   cu: ag   is 1: 2

therefore the moles of ag   =0.236   moles   x 2/1 =0.472   moles

step 3: find the mass   of ag

mass = moles x molar mass

from periodic table   the molar mass of ag =107.87 g/mol

mass   = 0.472   moles x 107.87 g/mol = 50.9 g

3.   the   much   silver   collected worth is   1.797 oz

  convert   50.9 g   to oz

that is   1 gram = 0.0353 oz

          50.9 grams =?   oz

by cross multiplication

={(50.9 grams x 0.0353 oz) / 1   gram}   =1.797 oz
