Answer:

Signal the driver behind you when it is safe to pass by turning on your four-way emergency flashers.

Avoiding casualties is the top priority when driving, the other choices given do not put whether there are cars in the other lane into consideration, therefore making them incorrect. Signaling the driver when it is safe gives you the time and them the gateway to pass, making a nice interaction keep you both alive.

What are the two types of furnaces used in steel production?
Kobotan [32]

Explanation:

The two types of furnaces used in steel production are:

<u>Basic oxygen furnace </u>

In basic oxygen furnace, iron is combined with the varying amounts of the steel scrap and also small amounts of the flux in the Blast Furnace. Lance is introduced in vessel and blows about 99% of the pure oxygen causing rise in temperature to about 1700°C. This temperature melts scrap and the impurities are oxidized and results in the liquid steel.

<u>Electric arc furnace</u>

Electric arc furnace reuses existing steel. Furnace is charged with the steel scrap. It operates on basis of electrical charge between the two electrodes providing heat for process. Power is supplied through electrodes placed in furnace, which produce arc of the electricity through scrap steel which raises temperature to about 1600˚C. This temperature melts scrap and the impurities can be removed through use of the fluxes and results in the liquid steel.

A high-voltage transmission line carries 1 000 A at 700 kV for a distance of 100 miles. If the resistance per length in the wire
mamaluj [8]

Answer:

50 MW

Explanation:

We are given;

Current = 1000A

Voltage = 700 KV

Resistance per length = 0.5 Ω/mile

Length = 100 miles

The total resistance would be;

R=0.5 Ω/mile x 100 miles = 50Ω.

Now, the current is the same throughout the wire, but the voltage is only at the beginning of the line, and thus the current for the power equation is;

P = I²R

So;

P=(1000A)² x 50Ω.= 50,000,000W = 50MW

What is the relationship between mechanical stress inside of a cylindrical part with a given force applied to it
Oliga [24]

The relationship between mechanical stress inside of a cylindrical part with a given force applied to it is stress = force/area.

<h3>How is pressure associated with strain?</h3>

The utility of pressure offers upward thrust to strain, however now no longer the opposite manner around. A pressure is a push or pull upon an item attributable to the item's interplay with some other item while Stress is an inner resistance to supplied through the frame itself each time it's far beneath a few type of deformation.

Stress is denoted through σ. It is represented as N/m2. Stress formulation is made use of to locate carried out on any given frame if pressure and region on which pressure is exerted is given withinside the problem.
