**Answer:**

remain the same constant

**Explanation:**

if a small gear is making 5 rpm turning a big gear thats making 1 rpm the bug gear is making lots of torque but if its going the opposite way its much harder to turn the big gear 1 rpm just to make the little gear do 5 rpm and it makes way less torque if thre both the same size there ging to stay the same speed

**Truth Table:**

let A = SW3, B = SW2, C = SW1, D = SW1

1. The truth table is attached in mage below. abcdefg are the 7 outputs of seven segment display.

2. K-maps of all 7 outputs is also attached as image to this response.

3. Outputs of seven segment display as SOP are as follows =

a = ~B~D + C + BD + A

b = ~B + ~C~D +CD

c = ~C +D +B

d = ~B~D + ~BC + B(~C)D + C(~D) + A

e = ~B~D + C~D

f = ~C~D + B(~C) +B(~D) + A

g = ~BC + B(~C) + A + B(~D)

**Answer:**

Pulser switch :-

Advertisements. A Switch is a device that makes or breaks a circuit or a contact. As well, it can convert an analog data into digital data.

Data switch :-

A switch box that routes an input signal to an output line; for example, to connect two computers to one printer. Manual data switches have dials or buttons. Automatic switches test for signals on the input lines and provide first-come, first-served switching.

**Answer:**

the percent increase in the velocity of air is 25.65%

**Explanation:**

Hello!

The first thing we must consider to solve this problem is the continuity equation that states that the amount of mass flow that enters a system is the same as what should come out.

m1=m2

Now remember that mass flow is given by the product of density, cross-sectional area and velocity

(α1)(V1)(A1)=(α2)(V2)(A2)

where

α=density

V=velocity

A=area

Now we can assume that the input and output areas are equal

(α1)(V1)=(α2)(V2)

Now we can use the equation that defines the percentage of increase, in this case for speed

Now we use the equation obtained in the previous step, and replace values

the percent increase in the velocity of air is 25.65%
