Achild (approximately 4 years old) takes her metal “slinky toy” (a flexible coiled metal spring) and does various tests to determine that the slinky has an inductance 130 µh, when it has been stretched to a length of 3 m. the permeability of free space is 4π × 10−7 n/a 2 . if a slinky has a radius of 4 cm, what is the total number of turns in the slinky?

Aforce of 34.5 newtons is applied to an object at an angle of 45 º with the horizontal. what is the force acting on the object in the horizontal direction?

What was the first instrument to ever record an earthquake?

Choose a realistic problem for which these are the correct freebody diagrams. be sure that the answer that the problem requests is consistent with the diagrams shown. choose a realistic problem for which these are the correct freebody diagrams. be sure that the answer that the problem requests is consistent with the diagrams shown. a 1.0 kg block is placed on top of a 2.0 kg block. a horizontal rope pulls the 2.0 kg block across a frictionless floor with a force of 21.0 n. the coefficient between the two blocks is 0.75. does the 1.0 kg block on top slide?
