<h3><u>Answer;</u></h3>

<em>Placing a magnetically hard material in a strong magnetic field</em>

<h3><u>Explanation</u>;</h3>
  • <em><u>Magnets</u></em> are those materials that generate magnetic field. Materials may either be <em><u>magnetic materials or non-magnetic materials</u></em>. <em><u>Non magnetic materials</u></em> are those materials that can not be attracted by a magnet while <em><u>magnetic materials</u></em> are those that can be attracted by a magnet.
  • <em><u>Magnetic materials</u></em> may be classified as either soft magnetic materials or hard magnetic materials based on the ease of magnetization. <em><u>Soft magnetic materials </u></em>are those materials that are easily magnetized and easily demagnetized while <em><u>hard magnetic materials </u></em>are hard to magnetize and demagnetized.
  • <em><u>Hard magnetic materials</u></em> are used to make permanent magnets. This is done by placing them in a strong magnetic field.

) A 0.10-kg ball, traveling horizontally at 25 m/s, strikes a wall and rebounds at 19 m/s. What is the magnitude of the change i
deff fn [24]

Answer:

The magnitude of the change in the momentum of the ball during the rebound is 4.4 kg-m/s.

Explanation:

Given that,

Mass of the ball, m = 0.1 kg

Initial speed of the ball, u = 25 m/s

Final speed of the ball, v = -19 m/s (the ball rebounds so it will be negative)

We need to find the magnitude of the change in the momentum of the ball during the rebound. The change in momentum of the object is equal to the difference of final and initial momentum.

\Delta p=m(v-u)

\Delta p=0.1\ kg\times (-19-25)\ m/s

\Delta p=-4.4\ kg-m/s

or

|\Delta p|=4.4\ kg-m/s

So, the magnitude of the change in the momentum of the ball during the rebound is 4.4 kg-m/s. Hence, this is the required solution.

A lever has a 36cm input arm and a 6cm output arm. find MA.
Nady [450]

6

Explanation:

The mechanical advantage is a factor that measures how input force increases using a machine.

A lever is a simple machine with the fulcrum at the center.

To calculate the mechanical advantage M.A of levers we use the expression below;

M. A = \frac{F_{b} }{F_{a} } = \frac{a}{b}

F_{a} = input force

F_{b} = output force

a is the distance of the input force from the fulcrum

b is the distance of the output force from the fulcrum

Given

a = 36cm

b = 6cm

M.A = \frac{36cm}{6cm} = 6
