From the following statements about mechanical waves, identify those that are true for transverse mechanical waves only, those that are true for longitudinal mechanical waves only, and those that are true for both types of waves. A. In longitudinal waves, the particles of the medium move parallel to the direction of the flow of energy. B. Many wave motions in nature are a combination of longitudinal and transverse motion. C. In transverse waves, the particles of the medium move perpendicular to the direction of the flow of energy. D. All of the above

D all of the above

Explanation:

All of the statements in the options are the character's exhibited by both longitudinal amd transverse waves.

Examples of transverse waves are water waves, light waves, radio waves, and also waves produced in strings and ropes.

Examples of longitudinal waves includes : vibrating turn fork,, drum head etc

answer; (arch); good luck

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.
