Create a 2D graph by plotting multiple data series on the same axes, using a resolution of at least 0.1 between points. Choose your axis limits so that all three mathematical functions show at least 2 full iterations. Ensure axes are all labelled, and each data series has a different line style, marker and colour.

y = f(x) = sin(x)
y = f(x) = cos(x)
y = f(x) = tan(x)

5. b) Discuss three examples of space division multiplexing encountered in our day-to-day life.

2. b) Noise voltage from a 50 Ω resistor obtained after amplification by an amplifier with 60 dB voltage gain is 100 mV at 27º C. Calculate the bandwidth of the amplifier. What will be the noise voltage if the temperature is increased to 57º C?

how we convert an insulator to conductors?

A helium filled balloon (mass = 0.2 kg) is rising in the air with the buoyant force = Fb = [1.29e^(-1.21h)]g where h is in km.


How would I go about finding an expression for the velocity as a function of height by integrating acceleration?

A truck moving at 5 m/s is about to accelarate at the rate of 2 m/s in 3s.after 3s the driver saw a old lady about to cross the road and it took 0.8 sec before it hits the brake. If the maximum braking deceleration is 5m/s2 and its distance of the truck to the old lady is 50m. Does the old lady hit by the truck?

Decent vehicle is traveling vertical@ 5.5 m/s and has horizontal velocity of 3.5 m/s . What speed and angle is descent path ?

A mass m of 400g hangs from the rim of a wheel of radius=15cm when released from rest the mass falls 2m in 6.5 sec. Find the moment of inertia of the wheel.

- A 2.7 kg ball is thrown upward with an initial speed of 20.0m/s from the edge of a 45.0m high cliff. At the instant the ball is thrown, a woman starts running away from the base of the cliff with a constant speed of 6.0m/s. The woman runs in a straight line on level ground, and air resistance acting on the ball can be ignored .(a) At what angle above the horizontal should the ball be thrown so that the runner will catch it just before it hits the ground, (b) How far does the women run before she catches the ball

A spacecraft orbiting a planet goes out of control and starts falling towards a planet. The spacecraft falls 1200 meters in the first 10 seconds after which the retro-rocket fires and the craft starts to accelerate upwards at 0.5 g 9( 1 g = 9.81 m/s²)

a. How long after the rocket fires does the craft stop falling?
b. How much further does the craft fall before stopping?
c. How many seconds after the rocket fires does the craft reach its original point?
