A stationary radar device emits a pulse at 10 Gigahertz. A
vehicle is coming towards the device and reflects a signal with a
difference of 1.33 kHz. Is this signal a lower or higher frequency?
What is the speed of the vehicle?
A motorist is targeted by police radar when approaching a
traffic control post. The radar emits at the frequency f=2.5 x 109
Hz and receives the reflected wave at a frequency of 250 Hz higher.
Calculate the speed of the car.
Determine the expression of the wave equations for the electric
and magnetic fields emitted by the radar. The average intensity is
40 W/m2. The wave propagates in the direction of Y>0. The
electric field of the wave is maximum...
an L band radar operating at 1.25GH uses a peak pulse
power of 3MW and must have a range of 185.2km for objects whose
radar cross section is 1m^2. If the minimum receivable power of the
receiver could have , assuming it to be full paraboloid with k=
0.65?
Consider the situation where one IOLab device rolls into another
stationary IOlab device and they stick together and they roll off
together. When answering the following questions, answer them
specifically for this situation.
How could you calculate the total momentum before the collision?
How could you calculate the total momentum after the collision?
How could you calculate the total kinetic energy before the
collision?
How could you calculate the total kinetic energy after the
collision?

A bird is flying directly toward a stationary bird-watcher and
emits a frequency of 1380 Hz. The bird-watcher, however, hears a
frequency of 1450 Hz. What is the speed of the bird, expressed as a
percentage of the speed of sound?
A bird flying directly toward a stationary bird-watcher emits a
cry at a frequency of 1,030Hz. The bird-watcher hears a frequency
of 1120 Hz. The speed of sound on this day is 341m/s. a,What is the
speed of the bird? b, Now there are two birds emitting a cry at
1,030Hz. Both are flying east, one on each side of the birdwatcher.
One is flying at 23m/s while the other is flying at 33m/s. Is there
anything the birdwatcher can...
FOR PULSE OXIMETER:
1. The overall purpose of the device and clinical condition it
looks to diagnose or treat
2. What type of biosignal the device records and how that signal
originates in the body and where (comment on SI
units, range, variability)
3. The underlying electronic circuitry and rationale behind the
signal processing
4. Typical sensitivity/specicity performance of the device
(PLEASE BE SPECIFIC AND WRITE OUT DETAILED ANSWERS.)
Que1.Consider two balls of identical mass. If ball 1 is moving
to the right towards stationary ball 2 at 1.0 m/s and the two balls
collide elastically, what will the final velocities of both balls
be? (Hint: consider this simulation.)
Que 2.If the same two balls again undergo a collision, but this
time the collision is inelastic, what will the final velocities of
both balls be?
Que 3.What are the conditions for elastic and inelastic
collisions?
Que 4.Explain how the...

Asteroid X, speeding at 100 m/s towards an equally massive but
stationary asteroid Y, collides with a glancing blow. After
collision, X is deflected at 35 degrees from its original direction
while Y travels at 45 degrees to the original direction of X,
assume total momentum is conserved.
a. Find the speed of each asteroid after collision.
b. What fraction of the original KE is lost in the
collision?
