I'd say A. because an inference is a guess/estimate. You can assume that the egg rolled off the kitchen but you know that C and D are true.
If both waves have the same wavelength, then the amplitude of
their sum could be anything between 1 cm and 9 cm, depending
on the phase angle between them.
If the waves have different wavelengths, then the resultant is a beat
with an amplitude of 9 cm.
m = 43.2 kg
Explanation:
volume of sphere = (4/3)pi(r)^3
= (4/3)(3.14)(2 m)^3
= 33.5 m^3
density = mass/volume
or solving for mass m,
m = (density)×(volume)
= (1.29 kg/m^3)(33.5 m^3)
= 43.2 kg
-Slow down
-Speed up
-Turning

The problem is most likely that the commutator brushes bounces as the motor shaft rotates.
<h3>What is a DC motor?</h3>
This is referred to a device which converts direct current electrical energy into mechanical energy.
if the commutator brushes bounces as the motor shaft rotates over different materials, the ticking sound is heard.
