Two parallel conducting plates are separated by 9.2 cm, and one of them is taken to be at a potential of zero volts.What is the

electric field strength between them in V/m, if the potential 8.8 cm from the zero volt plate is 475 V? What is the voltage between the plates in V?

Answer:

E=54V/cm

\Delta V=496.8V between the plates.

Explanation:

The equation for change of voltage between two points separated a distance d inside parallel conducting plates (<em>which have between them constant electric field</em>) is:

\Delta V=Ed

So to calculate our electric field strength we use the fact that the potential 8.8 cm from the zero volt plate is 475 V:

E=\frac{\Delta V}{d}=\frac{475 V}{8.8cm}=54V/cm

And we use the fact that the plates are 9.2cm apart to calculate the voltage between them:

\Delta V=Ed=(54V/cm)(9.2cm)=496.8V

7. A thin wire was wound 30 times closely over a boiling tube. The total length of the windings as measured was found to be 6.3m
faltersainse [42]

Answer:

Diameter of wire = 0.00021 meters

Explanation:

Given the following data;

Number of windings = 30

Length of windings = 6.3 mm to meters = 0.0063 meters

To find the diameter of the wire, we would use this mathematical expression;

Length of windings = number of windings * diameter of wire

Substituting the values into the expression, we have;

0.0063 = 30 * diameter of wire

Diameter of wire = 0.0063/30

Diameter of wire = 0.00021 meters

Select the correct location on the image.<br> Identify the magnetic north pole of Earth’s magnet.
OverLord2011 [107]

The magnetic north pole of the earth's magnet is in the geographic south pole.

  • There are two magnetic and geographic poles each, north and south
  • The two geographic poles are the locations where the earth's axis of rotation passes through which is imaginary
  • The magnetic north and south poles are not the same as the geographic north and south poles
  • In a compass, the needle points to the magnetic north pole
  • By convention, the magnetic north pole corresponds to the geographic south pole
  • The magnetic south pole corresponds to the geographic north pole
  • The magnetic field lines of a magnet start from the magnetic north pole and end at the magnetic south pole

The magnetic north pole of the earth's magnet is the geographic south pole.

Taya2010 [7]

Answer:

1) True, 2) True, 3) False, 4) False, 5) False

Explanation:

1) True. Dissipative energy cannot be recovered, in general it is a form of heat

2) True. The dissipation can be by radiation, heat

3) False. Mechanical energy is divided into K and U but not in equal parts

4) False. When there are dissipative interactions, part of the mechanical energy is set in the form of heat, so its value decreases

5) False. Mechanical energy is the sum of those two energies
