Answer:

Yes,

NO,

Yes,

No.

Explanation:

CASE: A wire is moved through the field of a magnet

As the wire is moved through the field of a magnetic the magnetic flux through the circuit loop changes,; therefore current is induced.

CASE: A magnet is held close to a wire

There needs to be relative motion between the wire and the magnet for the current to be induced; therefore, simply holding a magnet close to a wire will not induce current in the circuit.

CASE: A magnet is moved into a coil of wire

As the magnet is moved into a coil of wire, the magnetic flux through the coil changes, and therefore, the current is induced.

CASE: A magnet is moved out of coil of wire

Moving a magnet out of coil of wire also changes the magnetic flux through the coil; therefore, the current is induced.

CASE: A magnet rests in coil of wire

There needs to be relative motion between the coil of wire and the magnet for the current to be induced; therefore, a magnet resting in the coil of wire will no induce any current in the coil.

Dahasolnce [82]

<span>A substance that accelerates the rate of chemical reaction is called a catalyst. It serves as an alternative pathway for the reaction product. The increase of rate of chemical reaction is because catalyst has low activiation energy than the original pathway. The low activation energy will increase the amount of molecules that can benefit in the energy created by the catalyst.</span>

Answer:

a) yield strength

$\sigma_y = \dfrac{F_y}{A} = =\dfrac{48000}{100} = 480 MPa$
