Design a circuit which takes two inputs and outputs a 1 if and only if the two inputs are the same signal. You may only use two
Ivan

Answer:

Q = A ⊕ B = (A AND B) + ( not(A) AND not(B) )

Explanation:

AND gates : only output 1 when both inputs are 1

OR gate:  only output 1 when either or both of the inputs are 1

NOT gates: takes only one input ad output the opposite of the input

The required circuit should takes two inputs and outputs a 1 if and only if the two inputs are the same signal.

The two possible scenarios : both input are 1's or 0's

Q = A ⊕ B = (A AND B) + ( not(A) AND not(B) )

A  B  not(A) not(B)  A AND B    not(A) AND not(B)   Q

0  0     1          1            0                      1                       1

0   1      1         0            0                     0                       0

1    0     0        1             0                     0                       0

A horizontal disk with a radius of 23 m rotates about a vertical axis through its center. The disk starts from rest and has a co
lys-0071 [83]

Answer:

time is 0.42 sec

Explanation:

Given data

radius = 23 m

angular acceleration = 5.7 rad/s²

to find out

time

solution

we know that radius is constant so that

tangential acceleration At = angular acceleration × radius   ............. 1

tangential acceleration =  5.7 × 23 = 131.1 m/s²

and

radial acceleration Ar =  (angular velocity)² × radius    ........................2

we consider angular velocity = ω

this is acting toward center

so

compare 1 and 2

At = Ar

5.7 r =ω³ r

ω = √5.7 = 2.38746 rad/s

so

ω = 5.7 t

2.387 = 5.7 t

t =  2.387 / 5.7

t = 0.4187

time is 0.42 sec

A student uses a microwave oven to heat a meal. The wavelength of the radiation is 8.97 cm. What is the energy of one photon of
krek1111 [17]

Answer:

The energy of one photon is 2.21x10⁻²⁴ J. Multiplied by 10²⁵ is 22.10 J.

         

Explanation:  

The energy (E) of a photon is:

E = h\frac{c}{\lambda}

Where:

h: is the Planck's constant = 6.62x10⁻³⁴ J.s

λ: is the wavelength of the radiation = 8.97 cm

c: is the speed of light = 3.00x10⁸ m/s

E = h\frac{c}{\lambda} = 6.62 \cdot 10^{-34} J.s\frac{3.00\cdot 10^{8} m/s}{8.97 \cdot 10^{-2} m} = 2.21 \cdot 10^{-24} J

Hence, the energy of one photon is 2.21x10⁻²⁴ J.

Now, if we multiply the answer by 10²⁵ we have:

E = 2.21 \cdot 10^{-24} J \cdot 10^{25} = 22.10 J

I hope it helps you!

A roadway for stunt drivers is designed for racecars moving at a speed of 40 m/s. A curved section of the roadway is a circular
Fynjy0 [20]

Answer:

Bank angle = 35.34o

Explanation:

Since the road is frictionless,

Tan (bank angle) = V^2/r*g

Where V = speed of the racing car in m/s, r = radius of the arc in metres and g = acceleration due to gravity in m/s^2

Tan ( bank angle) = 40^2/(230*9.81)

Tan (bank angle) = 0.7091

Bank angle = tan inverse (0.7091)

Bank angle = 35.34o
