Answer:

A resistor

Explanation:

A diode is an electrical device that allows current to pass through it only in one direction. When a diode is forward biased, it allows current to flow through it in direction but when it is reverse biased, it stops current from flowing through it.

The maximum forward current is the maximum current allowed to flow through the diode when conducting in the forward bias condition. If the maximum forward current is exceeded, it leads to heat which causes damage to the diode.

A resistor is conducted in series to the forward biased diode to limit the current flowing through it thereby ensuring that the current is below the maximum forward current.

Give the approximate temperature (in K) at which creep deformation becomes an important consideration for each of the following

andrezito [222]

Answer:

691K, 543K, 725K, 1473K, 240K, 373K

Explanation:

Creep deformation of any metal is the transformational tendency of a metal to distort rapidly or slowly when attacked by any form of mechanical stress. The temperature significant for a metal to deform is gotten by the division of the actual temperature of the metal by its melting point. This is termed homologous temperature which is 0.4 or higher. It is calculated by the equation:

0.4Tm

Therefore for the listed metals...

For Nickel, 0.4Tm = 0.4 ×(1455 + 273) = 691 K

For Copper, 0.4Tm = 0.4 ×(1085 + 273) = 543 K

For Iron, 0.4Tm = 0.4 ×(1538 + 273) = 725 K

For Tungsten, 0.4Tm = 0.4 ×(3410 + 273) = 1473 K

For Lead, 0.4Tm = 0.4 × (327 + 273) = 240 K

For Aluminium, 0.4Tm = 0.4 ×(660 + 273) = 373 K

If coolant is mixed 50-50 with water, what is the freezing point?

sashaice [31]

Answer:

-35 degrees F

When mixed in equal parts with water (50/50), antifreeze lowers the freezing point to -35 degrees F and raises the boiling temperature to 223 degrees F. Antifreeze also includes corrosion inhibitors to protect the engine and cooling system against rust and corrosion.

Question 6: Which of the following is NOT true if you are changing into a

baherus [9]

Answer:

You should activate your signals 100 feet before you turn, becuase of that you should not wait until you are turning to turn on your signals. If you do not have working lights use your hands. So the answer that is inccorect is B.

You should activate your signals when you get into the turn lane is <u>NOT true</u>

Because you are supposed to single beforhand not while you're in the lane.

Im taking my drivers ed too. :)
