A radio wave is generated by a transmitter and then detected by a receiver. An antenna allows a radio transmitter to send energy into space and a receiver to pick up energy from space. Transmitters and receivers are typically designed to operate over a limited range of frequencies.

Answer:
SI unit of density - Kilogram per cubic metre (Kg/m³)
CGS unit of density - gram per cubic centimetre (g/cm³)
Angles at a point make 180° at a straight line.
Lx = 180° - (90+90)
Lx is 70°
Lx = 180° -(64+71)
= 180° - 13J°
= 45°
By using sine law
21/siny = length of pole/ sin 64
∴Length of pole = 21 sin 64/sin u5 = 26.69
Then the length of pole = 27ft
Weight is force.
The CGS unit of force is the dyne.
The SI unit of force is the Newton.
The formula we use
here is:
radial acceleration =
ω^2 * R <span>
110,000 * 9.81 m/s^2 = ω^2 * 0.073 m
<span>ω^2 = 110,000 * 9.81 / 0.073
ω = 3844.76 rad/s </span></span>
<span>and since: ω = 2pi*f --> f = ω/(2pi)</span><span>
f = 3844.76 / (2pi) = 611.91 rps = 611.91 * 60 rpm
<span>= 36,714.77 rpm </span></span>
