Answer:

-At 1000°C, liquid phase at 68 wt% Zn

-At 760°C, liquid+γ phase, liquid at 74 wt% and 66 wt% γ phase

-At 600°C, γ phase

-At 400°C, γ phase

Explanation:

The phase diagram will be used for the combination of the copper-zinc alloy, first 68% by weight of Zn will be located on the axis corresponding to the composition. Draw a vertical line upwards and go through the temperatures given by the exercise 1000, 760, 600 and 400 ° C. Later you have to know the phases for each of the temperatures. Draw a horizontal line within each phase and look at the adjacent phases and the composition of the alloy. For each of the temperatures, the phases are in response and the drawings are attached to the image.

Gina is about to use a fire extinguisher on a small fire. What factor determines the
Effectus [21]

Answer:

Each portable fire extinguisher should only be used for its specific type of fire. Class A extinguishers could cause a Class B fire to spread or electrocution in a Class C fire. A Class B extinguisher could fail to completely extinguish a Class A fire, causing the flame to re-ignite later.

Which of the following impulse responses correspond(s) to stable LTI systems? (a) h1(t) = e-(1-2j)ru(t) (b) h2(t) = e-r cos(2t)u
Illusion [34]

Answer:

LTI system is stable if Impulse response is finite.

so the correct answer is "b"

(b) h2(t) = e-r cos(2t)u(t)

Can anyone solve this for me?sequential circuit ,flipflop
andrezito [222]

Explanation:

We assume the T flip-flop changes state on the rising edge of the clock input.

The first stage is connected to the clock. The second stage clock is connected to the inverse of the Q output of the first stage, so that when the first stage Q makes a 1 to 0 transition, the second stage changes state.
