<h3><u>Answers;</u></h3>

Metals can become magnetic if they have many spinning electrons that create magnetic fields.

<h3><u>Explanation</u>;</h3>
  • <em><u>Magnets are materials that have the capability of generating magnetic fields. </u></em>They repel non-magnetic materials such as wood, plastic etc. and attract magnetic material such as iron and steel.
  • <em><u>Magnetic materials such as iron and steel may be used to make magnets by the process of magnetization.</u></em> In these magnetic materials such as iron, cobalt and nickel,electrons spin in the same directions which makes the, magnetic but not yet magnets.
  • For metals to attain magnetism they have to be magnetized by having them enter the magnetic field of an existing magnet.

Find the speed of light in each of the following materials. (a) gallium phosphide m/s (b) carbon disulfide m/s (c) benzene
Oksanka [162]

Explanation:

We need to calculate the speed of light in each materials

(I). Gallium phosphide,

The index of refraction of Gallium phosphide is 3.50

Using formula of speed of light

v=\dfrac{c}{\mu}....(I)

Where, \mu = index of refraction

c = speed of light

Put the value into the formula

v=\dfrac{3\times10^{8}}{3.50}

v=8.6\times10^{7}\ m/s

(II) Carbon disulfide,

The index of refraction of Gallium phosphide is 1.63

Put the value in the equation (I)

v=\dfrac{3\times10^{8}}{1.63}

v=1.8\times10^{8}\ m/s

(III). Benzene,

The index of refraction of Gallium phosphide is 1.50

Put the value in the equation (I)

v=\dfrac{3\times10^{8}}{1.50}

v=2\times10^{8}\ m/s

Hence, This is the required solution.

Does mechanical advantage have units? Explain your answer.
motikmotik

Answer:

The mechanical advantage of a machine is the ratio of the load (the resistance overcome by a machine) to the effort (the force applied). For an ideal (without friction) mechanism, it is also equal to: There is no unit for mechanical advantages since the unit for both input and output forces cancel out.
