Main Answer: The NOR gate is universal, which means that it can be used to implement any other logical function. This can be demonstrated by showing how to build the AND, OR, and NOT functions using a two-input NOR gate.
Supporting Answer: To build an AND gate using a two-input NOR gate, we can take the output of the NOR gate and pass it through an inverter (a NOT gate) to obtain the AND function. Specifically, we connect the two inputs of the NOR gate together to create a single input, and then we connect this input to the input of an inverter. The output of the inverter is then the AND function.
To build an OR gate using a two-input NOR gate, we can connect the inputs of the NOR gate to the inputs of two inverters (NOT gates). The outputs of the inverters are then connected together to create a single input for the NOR gate. The output of the NOR gate is then the OR function.
To build a NOT gate using a two-input NOR gate, we simply connect one input of the NOR gate to the output of the gate, leaving the other input disconnected. The output of the gate is then the inverted input.
Therefore, we have shown that a two-input NOR gate can be used to implement the AND, OR, and NOT functions, and therefore, the NOR gate is universal.

Elevators being hoisted up by a pulley
Using nylon ropes in rock climbing
Running a race around a track
Plane taking off from a runway
Impulse is important because it is the force that changes an object's momentum.
What is momentum?Momentum is a physical concept that describes the movement of an object due to the product of its mass and velocity. Momentum is a vector quantity, meaning it has both a magnitude and a direction. In classical mechanics, momentum is conserved, meaning that the total momentum of a system remains constant over time.
In the examples given, impulse is what allows the elevator to be hoisted up, the nylon ropes to hold a climber's weight, the runner to move around the track, and the plane to take off from the runway. Without impulse, none of these activities would be possible.

Air flows steadily along a streamline from point (1) to point (2) with negligible viscous effects. The following conditions are measured: At point (1) z1 = 2 m and p1 = 0 kPa; at point (2) z2 = 10 m, p2 = 20 N/m2 and V2 = 0. Determine the velocity at point (1). Also calculate the change in each form of energy in the Bernoulli equation and describe, in words, the energy gain or loss by each form as the air flows from point (1) to point (2).
The velocity of the air flow at point (1) is 13.8 m/sec. The gravitational potential energy is increasing from point(1) to point(2) by 94.176 joules. The pressure head increased by 1.7 m of air column. Kinetic energy head is decreased by 9.71 m of air column.
Datum head at point (1), z₁ = 2 m

Pressure at point(2) p₂ = 20 N/m²
Velocity at point(2) v₂ = 0
Velocity at point(1) v₁ = ?
The density of air, ρ = 1.2 kg/m³
By applying Bernoulli's equation,
z₁ + p₁/ρg + v₁²/2g = z₂ + p₂/ρg + v₂²/2g
2 + 0 + v₁²/2g = 10 + 20/(1.2×9.81) + 0

= 94.176 Joules
Increase in the pressure head = p₂/ρg - p₁/ρg
= 1.7 - 0
= 1.7 m (of air column)
Change in the kinetic energy head = v₂²/2g - v₁²/2g
= 0 - v₁²/2g

When do a 1000kg car and a 2000kg truck have the same momentum?
When a car has double the speed of the truck
Momentum is calculated by multiplying the mass by the velocity. And we have masses of 1000 kg and 2000 kg and to make the momentum equal velocity needs to be inversely proportional.
Let the velocity of the car be x m/s
momentum (p) = mass * velocity
then momentum is 1000*x
1000x kgm/s
So lets the velocity of the truck be y m/s
the momentum of the truck will be 2000*y
so 2000y kgm/s
by the condition 1000x = 2000y
so on solving
x= y/2
which shows the car has double the velocity of the truck.
So we can conclude to greater momentum we need either velocity or mass needs to be greater or both can be also large to get higher momentum.

A car leaves a city with a speed of 90 mph. Three hours later and out of the same city another car in pursuit of the first leaves with a speed of 120 mph. Find the time it takes for the second car to reach the first.
Answer:
9 hours
Explanation:
When the 2nd car catches up to the first, both cars will have gone the same distance.
Distance = rate x time
Distance car 1 traveled when car 2 catches up = 90 mph(3 hr + t)
Distance car 2 traveled when it catches up to car 1 = 120t
90(3 + t) = 120t
270 + 90t = 120t
30t = 270
t = 270/30 = 9 hrs
Therefore, 12 hours after car 1 leaves the city and 9 hours after car 2 leaves the same city, they meet up.
To prove it:
90(12) = 120(9) = 1080 Car 2 catches up to Car 1 1080 miles from the city

A convex mirror forms an image of half the size of the object. When it is moved 15 cm away from the object, the size of the image becomes 2/5 times the size of object. Find the focal length of convex mirror. Answer is 30.
Answer:
focal length = 30 cm
Explanation:
You want the focal length of a convex mirror when moving the mirror an additional 15 cm away from the object causes its image size to decrease from 1/2 to 2/5 the size of the object.
Mirror equationThe relation between focal length (f), object distance (do) and image distance (di) is ...
1/f = 1/do +1/di
The ratio of heights is the same as the ratio of distances:
hi/ho =di/do
ApplicationIf we let do represent the original object distance, then (1/2)do = di, the original image distance. This gives one equation we need:
1/f = 1/do +1/(1/2do) = 3/do
Moving the mirror increases the object distance to (do+15). Now, the equation becomes ...
1/f = 1/(do+15) +1/(2/5(do+15)) = 7/(2(do+15))
SolutionSubstituting for 1/f, we have ...
3/do = 7/(2(do +15))
6(do +15) = 7do . . . . . . . . . cross multiply
90 = do . . . . . . . . . . . . subtract 6·do
Then the focal length is ...
1/f = 3/do
f = do/3 = 90/3 = 30
The focal length of the mirror is 30 cm.

If a 40 kg object has a momentum of 400 Kgm/s, how fast is it traveling
The object is traveling at 10 m/s.
Momentum is defined as the product of an object's mass and velocity. The formula for momentum is:
p=mv
where,
p = momentum
m = mass
v = velocity
We can use this formula to find the velocity of an object given its momentum and mass. To solve for velocity, we can divide both sides of the equation by mass:
velocity = momentum/mass
In this case, the object has a mass of 40 kg and a momentum of 400 Kgm/s, so we can plug in these values to find the velocity:
velocity = 400 Kgm/s / 40 kg = 10 m/s

The minimum value of the coefficient of static friction is 1.33.
What is the coefficient of static friction?To calculate the minimum value of the coefficient of static friction, we need to determine the force of static friction acting on the block. The force of static friction is equal to the force of gravity acting on the block (mg) multiplied by the coefficient of static friction (µs
m = 14.26kg
θ = 41°
g = 9.8 m/s²
The force of gravity acting on the block is given by the formula:
Fg = mg
where,
m = (mass of the block)
g = (acceleration due to gravity)
Fg = 14.26kg *9.8 m/s²
Fg = 139.75 N
The force of static friction can be found using the formula:
Fstatic = µs * N
where,
µs = coefficient of static friction (unknown)
N = Normal force acting on the block
The normal force acting on the block is equal to the force of gravity acting on the block perpendicular to the ramp.
N = mg * cos(θ)
where,
θ = 41 degrees (incline of the ramp)
N = 14.26kg * 9.8 m/s² * cos 41°
N = 105.47 N
So,
Fstatic = µs * (mg * cos(θ))
making µs subject of the formula and substituting already calculated vaues we get,
µs = Fstatic
(mg * cos(θ))
µs = 139.75 N

The distance moved by an object when it acted by a net force 1 N and time 3s is found to be 0.9m
Why is mass acceleration due to net force?According to this, an object's rate of change in velocity is directly proportional to the force used and moves in the direction of the applied force. The equation: summarises it. Mass (kg) times acceleration (m/s2) equals force (N). A constant mass item will therefore accelerate in direct proportion to the force exerted.
F = ma
acceleration = F/m => 1/5
v= u + at, u=0 (initially at rest);
v=at = distance/t = at;
S = distance => ut + 1/2at^2
=> 0 + 1/2 x 1/5 x 9 => 0.9m
the distance traveled by object in the given time 3s = acceleration x t2
How is acceleration calculated?The acceleration is determined by dividing the net force by the mass. An object's acceleration doubles if the net force exerted on it also doubles. Increased mass will result in a halving of acceleration. If the mass and net force are both doubled, the acceleration will remain constant.

The Earth's gravitational pull on the satellite is 651.8 N. Consequently, the satellite's gravitational pull on Earth is 651.8 N. As a result, the spacecraft accelerates at a rate of 1.5 m/s2.
Why does a satellite in a circular orbit not feel the effects of gravity?Centripetal force is used to maintain an object moving in a circle due to gravity. Since gravity always behaves perpendicular to motion, it has no effect on an item in a circular orbit.
Calculation:Mass of Telescope= 8410 kg
revolution in minutes = 927
G = 6.67 × 10-11 N ∙ m2/kg2
Mass of earth = 6.0 × 1024 kg
