If gear a rotates with a constant angular acceleration of aa = 90 rad> s2, starting from rest, determine the time required for gear d to attain an angular velocity of 600 rpm. also, find the number of revolutions of gear d to attain this angular velocity. gears a, b, c, and d have radii of 15 mm, 50 mm, 25 mm, and 75 mm, respectively.

solution:

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:

gravity
