Answer:

(B) the increase in the car's potential energy is 3,660,000 J

Explanation:

Given;

mass of the car, m = 1,000 kg

height through the car was drove, h = 366 m

acceleration due to gravity, g = 10 m/s²

The increase in the car's potential energy is calculated as;

P.E = mgh

P.E = 1000 x 10 x 366

P.E = 3,660,000 J

Therefore, the increase in the car's potential energy is 3,660,000 J

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.

Six automobiles are initially traveling at the indicated velocities. The automobiles have different masses and velocities. The d
Mumz [18]

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

P_1 = m v

P_1 = (1000)(10)

P_1 = 10^4 kg m/s

Yellow Car

P_2 = m v

P_2 = (2000)(5)

P_2 = 10^4 kg m/s

Blue Car

P_3 = m v

P_3 = (500)(20)

P_3 = 10^4 kg m/s

Light Blue Car

P_4 = m v

P_4 = (1000)(20)

P_4 = 2\times 10^4 kg m/s

Green Car

P_5 = m v

P_5 = (500)(10)

P_5 = 5 \times 10^3 kg m/s

Purple Car

P_6 = m v

P_6 = (4000)(5)

P_6 = 2\times 10^4 kg m/s

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

Force = \frac{impulse}{time}

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

lilavasa [31]

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.

Two cars, a Porsche Boxster convertible and a Toyota Scion xB, are traveling at constant speeds in the same direction. Suppose,
fenix001 [56]

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 = V_{A} × t

where  V_{A} is the speed of the car and t is time

the distance travelled by car B before reaching car A will be;

x + x₀ = V_{B} × t

Now lets replace x by V_{A} × t

so

(V_{A} × t) + x₀ = V_{B} × t

x₀ = (V_{B} × t) - (V_{A} × t)

x₀ = t (V_{B} - V_{A})

t = x₀ /  (V_{B} - V_{A})

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
