Awave traveling in water has a frequency of 250 hz and a wavelength of 6.0m. what is the speed of the wave?

Spend time observing or thinking about events that involve matter and energy. which events can you explain? which events can’t you explain?

Which type of wave can travel without a medium

Electromagnetic induction. a coil of wire contains n turns and has an electrical resistance r. the radius of each turn is a. initially, inside the coil there exists a uniform magnetic field of magnitude b0 parallel to the axis of the coil. the magnetic field is then reduced slowly. the current induced in the coil is i. how long does it take for the magnitude of the uniform field to drop to zero?
