The current density inside a long, solid, cylindrical wire of radius a = 3.4 mm is in the direction of the central axis and its magnitude varies linearly with radial distance r from the axis according to J = J0r/a, where J0 = 300 A/m2. Find the magnitude of the magnetic field at a distance (a) r=0, (b) r = 2.6 mm and (c) r=3.4 mm from the center.

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.

explanation:

wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves.

true tan speed = ang vel x radius
