Answer:
O So you can ask questions about steps you do not understand.
Explanation:
One of the reasons why it is encouraged that the laboratory procedure must be read at the beginning of any type of experiment is familiarize the student with the experimental procedure. Also, questions that can help make the smooth running of the experiment to proceed can be cleared.
- It is to this regard that understanding laboratory procedures is very vital.
- Students must grasp the details of each steps of the experiment before proceeding with their investigation.
- Other critical information needed to set up the experiment can also be brought into the lime light.
Answer:
Part a)
Purple car = Light Blue car > (Red car = Yellow Car = Blue car) > Green Car
Part b)
Purple car = Light Blue car > (Red car = Yellow Car = Blue car) > Green Car
Part c)
Purple car = Light Blue car > (Red car = Yellow Car = Blue car) > Green Car
Explanation:
Red car
mass = 1000 kg
speed = 10 m/s
Yellow car
mass = 2000 kg
speed = 5 m/s
Blue car
mass = 500 kg
speed = 20 m/s
Light Blue car
mass = 1000 kg
speed = 20 m/s
Green car
mass = 500 kg
speed = 10 m/s
Purple car
mass = 4000 kg
speed = 5 m/s
Part a)
Now we know that momentum of each car is product of mass and velocity
so we will have
Red Car



Yellow Car



Blue Car



Light Blue Car



Green Car



Purple Car



So the momentum is given as
Purple car = Light Blue car > (Red car = Yellow Car = Blue car) > Green Car
Part b)
Impulse is given as change in momentum so here we can say that final momentum of all the cars will be zero as they all stops and hence the impulse is same as initial momentum of the car
so the order of impulse from largest to least is given as
Purple car = Light Blue car > (Red car = Yellow Car = Blue car) > Green Car
Part c)
Force is defined as rate of change in momentum
Now let say all cars will stop in same time interval
so we will have

so we will have
force is in same order as that of impulse
so it is given as
Purple car = Light Blue car > (Red car = Yellow Car = Blue car) > Green Car

Answer: Analog transfer information quicker, example electromagnetic waves which are used in our modern day phones.
Explanation: Digital signals are a more reliable form of transmitting information because an error in the amplitude or frequency value would have to be very large in order to cause a jump to a different value. Signals are composed of infinite possible values. Signals are composed of only two possible values: 0 or 1.
Answer:
It will take 29.31 seconds for the Boxster to catch the Scion
Explanation:
Given the data in the question;
lets say Toyota Scion xB is car A and Porsche Boxster convertible is B and Toyota Scion xB is car A
the distance travelled by car A is
x =
× t
where
is the speed of the car and t is time
the distance travelled by car B before reaching car A will be;
x + x₀ =
× t
Now lets replace x by
× t
so
(
× t) + x₀ =
× t
x₀ = (
× t) - (
× t)
x₀ = t (
-
)
t = x₀ / (
-
)
so we substitute
t = 170 m / (24.4 - 18.6)
t = 170 / 5.8
t = 29.31 s
Therefore; it will take 29.31 s for the Boxster to catch the Scion
