Amplitude.

The amplitude A is the maximum elongation of each point of the wave with respect to the  central or equilibrium position.

In a sinusoid wave is the maximum distance in the absolute value of the curve measured from the x axis, can be represented as y(t) = A sen (ωx + φ).

Example:

y(t) = 10 sin (2πx), Where the amplitud of the sine wave is A = 10

A represents the amplitude of the wave. This measures the sound wave's intensity, or volume.  Pls mark brainliest. Have a nice day!

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:

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever
