Benzene was a ring of six carbon atoms! This was the structure that made him well known around the world
P = IV
I = P/V = 30 / 120 = 0.25 A.
Current = 0.25A
The freezing point ..... :)
Answer:
835.29 Hz
Explanation:
When moving towards the source of sound, frequency will be given by
f*=f(vd+v)/v
Where f is the freqiency of the source, vd is the driving speed, v is the speed of sound in air, f* is the inkown frequency when moving forward.
Substituting 800 Hz for f, 340 m/s for v and 15 m/s for vd then
f*=800(15+340)/340=835.29411764704 Hz
Rounded off, the frequency is approximately 835.29 Hz
Explanation:
(a) Frequency of radar energy, 
The relation between frequency and wavelength is given by :
or
(b) If wavelength, 
or
f = 1.2 GHz
Hence, this is the required solution.
