Hhhe meee fast!pplss Calculate the diameter of a 3.9-cm length of tungsten filament in a small lightbulb if its resistance is 88 . If 62mA current flows through the filament, find the potential difference across the source. (a) the diameter of the wire (in m) =
(b) Potential difference across the source in V =​

Which law represents the thermodynamic statement of the conservation of energy of a system? a. the fourth law b. the first law c. the second law d. the third law

The electric potential v is constant everywhere within a certain region of space. which statement below is true? the choices are: the electric field is also constant (but not zero) within the region. a charged particle placed within the region will experience an electric force. the electric field is zero everywhere within the region. the electric field varies from place to place within the region.

Does the distance travelled by an oscillating mass between times t=0 and t2 equal the displacement of the particle over the same time period if t2> t/2? hint: consider a sine wave starting at t1=0, then consider a closing wave starting at t1=0, for your explanation.
