Which part of the manufacturing process involves heating and rolling blocks of steel into flat sheets and bars?

faltersainse [42]

A. Forming

Explanation:

Metal forming is a metallurgical process which involves heating and rolling blocks of steel into flat sheets and bars.

Metal forming is the process of working metals and utilizing its properties to form different shapes.

Metal forming is made possible by metallic bonds in metals.
The bulk of the physical properties of metals can be attributed to these bond types.
In metal forming, metals are shaped into different substances.
Metal forming preserves the mass of the metallic body and the shapes modified by force.

When a 4-μf capacitor has a potential drop of 20 v across its plates, how much electric potential energy is stored in this capac

Genrish500 [490]

Thew energy stored in a capacitor of capacitance $C$ and voltage between the plates $V$ is

$E=\frac{1}{2} CV^2$ .

Substituting numerical value

$E=\frac{1}{2}(4*10^{-6}) (20)^2\\ E=800\; \mu J$

Average amount of time wind machines operate

Rasek [7]

The wind machine on an average operates for a time of about $\boxed{3-4\text{ hours}}$ .

Explanation:

The wind energy is the method of using the energy carried by the wind to generate the power. The wind energy is the considered as the conventional and clean source of energy.

The wind machines require the high power winds to rotate the blades of the windmill and produce power using the energy of the moving wind.

The winds blow at such high speed for a very small time during the day, the wind machine cannot be expected to work for a longer time during the whole day.

The wind energy can be obtained form a wind mill for a limited time unlike the other form of energy like thermal energy or even the solar energy. The thermal energy can be obtained at anytime due to burning of fuel whereas the solar energy can at least be obtained during the whole day time.

Thus, the wind machine on an average operates for a time of about $\boxed{3-4\text{ hours}}$ .

A wire carries a current of 6.91 A in a direction that makes an angle of 19◦ with the direction of a magnetic field of strength

g100num [7]

Answer:

4.454 N.

Explanation:

The force on a current carrying conductor in a magnetic field is given as,

F = BILsinФ................... Equation 1

Where F = magnetic Force, B = magnetic Field, I = current, L = Length of the wire, Ф = The angle between the conductor and the Field.

Given: B = 0.289 T, I = 6.91 A, L = 6.7 m, Ф = 19°

Substitute into equation 1

F = 0.289(6.91)(6.7)sin19

F = 0.289×6.91×6.7×0.33

F = 4.454 N.

Hence the magnetic force = 4.454 N.
