D. a and c

Explanation:

To make a generator out of a bicycle, Devon will need two magnets and coil of wire.

There is a close knit relationship between magnetism and electricity. Electricity can be generated by a wire changing flux in the presence of a magnetic field.

  • The magnets provide magnetic field for the process.
  • The coil of wire is placed in between the magnetic field generated by the magnets.
  • The bicycle pedal is connected to the set up to turn the wire in between the magnetic fields.
  • This way, electricity is produced.

The perimeter of a rectangle can be found using the equation P = 2L + 2W, where P is the perimeter, L is the length, and W is th
sweet [91]

Answer:

The perimeter of the rectangle is 60 units.

Explanation:

The perimeter of a rectangle is given by the equation P = 2L + 2W. With W = 12 units and L = 18 units, substituting the values in the equation above:

P = 2(18 units) + 2(12 units)

P = 36 units + 24 units

P = 60 units

What's a difference between mercury and oxygen?<br> (They both are elements)
borishaifa [10]

--  There are 80 protons in the nucleus of every atom of Mercury,
but only 8 of them in the nucleus of an atom of Oxygen.

-- Mercury must be warmer than 357°C in order to boil, but Oxygen
must only be warmer than -183°C.

--  Mercury must be colder than -39°C in order to freeze, but Oxygen
must be colder than -219°C.

--  Oxygen is required for human life.  Mercury is a deadly poison.

A metal wire is bent into a square and carries auniform current throughout it. The net magneticfield at the center of this squar
belka [17]

Answer:

The statement that the net magnetic field at the center of this square is zero is false.

The net magnetic field inside a conductor must be zero - This is a true statement

Explanation:

The net magnetic field at the center of this square is not equal to  zero.

The net magnetic field at the center of this square is given by the equation below:

B = 2√2μ₀I/πₐ

Where a = the side of the loop, and I is the current.

Thus, the statement that the net magnetic field at the center of this square is zero is false.

The net magnetic field inside a conductor must be zero - This is a true statement because the total charge on the conductor must be equal to zero.
