Digital information is converted and transmitted in certain numbers that create a pattern. Analog data is transmitted in continuous waves. Old records contain analog data but can be converted to digital recordings.

What acceleration will you give to a 25kg box if you push it with a force of 85N

Lightning occurs when there is a flow of electric charge (principally electrons) between the ground and a thundercloud. assume that the rate of charge flow in a lightning bolt is about 24000 c/s and this lasts for 105 µs or less.

If F1 = 390 N and F2 = 550 N, determine the angle θ (0∘≤θ≤180∘) between them, so that the resultant force has a magnitude of FR = 780 N. Express your answer to two significant figures and include the appropriate units.
