Compared with the amount of current in the filament of a lamp, the amount of current in the connecting wire is a. definitely less. b. often less. c. actually more d. the same.

D. the same.

Explanation:

The amount od current that flows through the filament of a lamp is actually the same that it would be compared with the amount of current that is flowing though the connecting wire, unless the lamp has a kind of resitor where it downgrades the amount of current befor it passes through the filament of the lamp, the currecnt should be the same.

c)as speed changes, wavelength and frequency change.

everything changes!

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.
