What is the wavelength of a wave that has a speed of 30 m/s and a frequency of 5.0 Hz? INCLUDE THE CORRECT UNIT!

Aplane flies directly between two cities, a and b, which are separated by . from a to b, the plane flies into a headwind. on the return trip from b to a, the wind velocity is unchanged. the trip from b to a takes less than the trip from a to b. what is the airspeed of the plane, assuming it is the same in both directions

At what time would the magnitude of the velocity reach 36.00 km/hr

Why does the liquid rise up through the dip tube when the valve is open
