Two synchronized microwave sources, a and b, are emitting waves of wavelength 4.0 cm. source a is located on the x-axis at x = 0, source b can be moved along the x-axis, and a microwave receiver is fixed on the x-axis at x = 94 cm. for each of the following positions of source b determine whether the waves from the sources will reach the receiver in phase (constructive interference), out of phase (destructive interference), or with a phase difference of π/2 rad.

when the velocity of a mass on a spring is zero, the acceleration is at a maximum .

0.3x0.21x0.08kg=mass 1 sheet

mass 500 = 500xmass 1

volume pile = 0.3x0.2x0.048

density=mass/volume= 500xmass 1/0.3x0.2x0.048

explanation:

duh.

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
