A machine weighing 2600 lb is mounted on springs of stiffness 10000 lb/in. Inside the machine a piston that weighs 60 lb moves up and down at a speed of 600 RPM and a stroke of 15 in. The motion of the piston is a sine wave. What is the magnitude of the forced transmitted to the foundation

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:

frequency or wavelenth of em radiation in a vacuum
