shows a circular region of radius R = 3.50 cm in which an electric flux is directed out of the plane of the page. The flux encircled by a concentric circle of radius r is given by ΦE, enc = (0.819 V·m/s)(r/R)t, where r ≤ R and t is in seconds. What is the magnitude of the magnetic field that is induced at radial distances (a)2.50 cm and (b)7.00 cm

a. B = T

b. B = T

Explanation:

Given that:

the flux  ΦE,enc =

radius R = 3.50 cm = 0.0350 m

when r = 2.50 cm = 0.0250 m

Let B be the strength of the magnetic field inside then:

the magnitude of the magnetic field  that is induced at radial distance of 2.50 cm is:

B = T

Let B be the strength of the magnetic field outside then:

the magnitude of the magnetic field  that is induced at radial distance of 7.00 cm is:

B = T

weather forecasts are done by collecting data about the current state of the atmosphere mainly the temperature, humidity and wind and using meteorology, to determine the atmosphere that evolves over time. the h and l mean the high and low pressure. the red strip is a warm front. the blue strip is a cold front. the blue and red strip is a stationary front. the purple strip is a occluded front.
