Assuming that voltage remains constant, what happens to the current in a filament if it is replaced by a longer wire?
Elena L [17]

Answer:

Choice B: The current decreases.

Explanation:

The resistance of a conductor is proportional to its length when radius and resistivity stays the same. The resistance of the longer filament will be greater than the resistance of the initial one.

For Ohmic conductors,

\displaystyle I = \frac{V}{R},

where

  • I is the current through the conductor,
  • V is the voltage across the conductor, and
  • R is the resistance of the conductor.

Voltage here stays the same. Increasing the resistance R of the conductor will reduce the current.

The filament might heat up over time. The filament might not be an ohmic conductor. Still, a similar trend shall exist. Resistance will be greater in the longer filament, and current will decrease.

Choose the correct description, of what happens to the electron speeds in a more massive white dwarf. Choose the correct descrip
tester [92]

Answer:

As the mass of a white dwarf increases, the pressure must increase to resist gravity. To do this, the electrons must move faster.

Explanation:

A white dwarf also known as degenerate dwarf is a star or an electron degenerate matter and is as massive as the Sun but only about as large in size as planet Earth.

The maximum mass of a white dwarf is about 1.4 times the mass of the Sun.

Also, as the mass of a white dwarf increases, the pressure must increase to resist gravity and to do this, the electrons must move faster.

Answer the question with step.​
Maru [420]

Answer:

f1/f2 =W1/W2 = 1/3

.0 f2 = 3f1

As ,

1/F= 1/f1 +1/f2

...1/40 = 1/f1 - 1/3f1

f1=> 80/3 cm

... f2 = 2f1 = 3 x 80/3 = 80 cm
