What part of a tidal power plant is the tidal water pushed through to generate electricity a. turbine b. barrage c. boat d. dam

a. Turbine

The turbine converts the kinetic energy of falling water into mechanical energy.

Answer : Turbine is used to generate electricity in tidal power plant.

Explanation :

In tidal power plant, the kinetic energy of moving water is used to generate electricity. It is one of the renewable source of energy.

The turbine is a part of the tidal power plant which is used to generate electricity. It is kept on the floor of the sea where there is a very strong tidal flow.

The turbines used in tidal power plant is very expensive as compared with the wind turbines.

Hence, the correct option is (a) " turbine ".

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.
