A traffic policeman hiding behind a signboard detects a car
speeding past him with a constant speed of 150 km/h. He starts his
motorcycle 3.0 seconds later and carried out a pursuit,
accelerating uniformly at 12 m/s2. Calculate the largest separation
in meters between the car and the motorcycle before the
interception
consider the conceptual physics behind the visual
process. explain how the curves of the cornea and the lens relate
to the angle of light waves projection.
describe some of the changes or problems in the eye
structure that can cause a problem with vision.
describe some of these problems and the way they alter
or block like ways for example, cataracts obstruct light waves,
thereby causing problems with vision.
describe the role of photoreceptors and their location
in the eye....
Describe Density Waves in traffic
Imagine you are driving one such car. Describe what happens
before you encounter the truck, as you wait behind it, and after
you pass it. Address your speed, and the "density" of the traffic
around you.
A car is going at 11.2 m/s on a horizontal straight road. When
the traffic light is 30 m away, it turns red.
The reaction time of the driver is 0.3 s.
The car stops just before the traffic light with constant
deceleration when the break is applied.
Find the time it takes for the car to stop, from the moment the
light becomes red.
Plot speed of the car on y-axis and the time on the x-axis,
taking t=0...
A grocery store is trying to predict how many packages of toilet
paper rolls will be purchased over the next week. They know from
their records that each customer has a 60% chance of buying 0
packages, a 30% chance of buying 1 package, an 8% chance of buying
2, and a 2% chance of buying 25. They expect about 150 customers
per day.
(a) What is the expected number of packages sold in one day? (b)
What is the...

Describe the mechanism behind the expression of an eukaryotic,
post-translational polypeptide that is repressed when the gene
producing it is turned off due to a threshold concentration being
reached.
