Answer: The correct answer is D.

Explanation:

When the iron is placed in the magnetic field then it will magnetize and behave like a temporary magnet. The domains of the iron will align.

Magnetically soft material: It is an temporary magnet which is made from a material that is magnetized. It creates its own magnetic field. For example, magnetically soft material is an electromagnet. The direction of this material can be changed easily.

In the given problem, a magnetically soft material is placed in a strong magnetic field. The domains of the magnetically soft material are already aligned but when this material is placed in the magnetic field then the domains will easily realign.

Therefore, the magnetically soft material will become a temporary magnet because the domains will easily realign.

A 0.5 kg mass on a spring undergoes simple harmonic motion with a total mechanical energy of 12 J. If the oscillation amplitude
Darya [45]

Answer:

The frequency of the oscillation is 2.45 Hz.

Explanation:

Given;

mass of the spring, m = 0.5 kg

total mechanical energy of the spring, E = 12 J

Determine the spring constant, k as follows;

E = ¹/₂kA²

kA² = 2E

k = (2E) / (A²)

k = (2 x 12) / (0.45²)

k = 118.519 N/m

Determine the angular frequency, ω;

\omega = \sqrt{\frac{k}{m} } \\\\\omega =  \sqrt{\frac{118.519}{0.5} } \\\\\omega = 15.396 \ rad/s

Determine the frequency of the oscillation;

ω = 2πf

f = (ω) / (2π)

f = (15.396) / (2π)

f = 2.45 Hz

Therefore, the frequency of the oscillation is 2.45 Hz.

Which of these is not an example of
prohojiy [21]

Answer:

A) The process that give us day  and night.

Explanation:

From the answer choices provided the one that is not an example of this is the process that give us day  and night. This is because, the day/night cycle occurs as the Earth spins on it's axis. This cause one side of the Earth to be facing the Sun, which is the side that is currently experiencing day time while the other side is experiencing night time. As the Earth spins the cycles repeat. This is not an example of revolving.
