Ocean tides are waves that have a period of 12 hours, an amplitude (in some places) of 1.50 m, and a speed of 750 km/hr. what is the distance between adjacent crests of these waves?

distance between adjacent crests = 9000 km

Explanation:

given data

time period = 12 hours

amplitude = 1.50 m

speed = 750 km/hr

solution

we get here distance between adjacent crests that is express as

distance between adjacent crests = speed × time 1

put here value and we get

distance between adjacent crests = 750 × 12

distance between adjacent crests = 9000 km

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.

explanation:

it becomes positively charged by charging it
