Tarik winds a small paper tube uniformly with 189 turns 189 turns of thin wire to form a solenoid. The tube's diameter is 7.99 mm 7.99 mm and its length is 2.19 cm 2.19 cm . What is the inductance, in microhenrys, of Tarik's solenoid?

Modify the equation fδt=δ (mv) to find the force of friction.

The 10-kg double wheel with radius of gyration of 125mm about o is connected to the spring of stiffness k = 600 n/m by a cord which is wrapped securely around the inner hub. if the wheel is released from rest on the incline with the spring stretched 225 mm, calculate the maximum velocity v of its center o during the ensuing motion. the wheel rolls without slipping

Select light for the type of wave, adjust the wavelength so that the light is red, and increase the amplitude of the light to the max. then, select the start button at the source location to begin producing the waves. light is a form of electromagnetic wave, containing oscillating electric and magnetic fields. the wave amplitude detector mentioned above shows how the electric field oscillates in time at the location of the probe. the amplitude of the wave at the location of the probe is equal to the maximum electric field measured. how does the amplitude of the wave depend on the distance from the source?
