b. state 2 properties of electromagnetic radiation (emr)
c. an emr makes one complete oscillation in 12 seconds. if the frequency of oscillatien is
0.0833hz calculate the following:
(i) wavelength (ii) angular velocity (iii) photon energy of the radiation
(c = 3.0 x 109 m/s, h = 6.626 x 102).s, n = 22 of 3.142)

answer is a

explanation:

c)red bank

explanation:

red bank is a borough in monmouth county, new jersey, incorporated in 1908 and located on the navesink river, the area's original transportation route to the ocean and other ports.

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
