Answer:

The answer to your question is below

Explanation:

Data

m = 3 kg

vo = 6 m/s

vf = -8 m/s

Process

a= Initial kinetic energy

    Eko = (1/2)mv²

    Eko = (1/2)(3)(6)²

    Eko = 54 J

b) Final kinetic energy

    Eko = (1/2)(3)(-8)²

    Eko = 96 J

c) Initial momentum

   pi = (3)(6)

   pi = 18 kg m/s

d) Final momentum

   pf = (3)(-8)

   pf = -24 kg m/s

A car driving at a constant speed of 64 mi/h travels 68 miles. How many hours did this take?
babymother [125]
64 miles/hour
Therefore 1/64 hours/mile
68 miles * 1/64 hours/mile (notice how miles cancels out)
Therefore the answer is 68/64 hours = 1.0625 hours = 1 hour 3min and 45sec.

I would like to know why this is the correct answer
Marta_Voda [28]

Answer:

see below

Explanation:

First, the obvious, as you press the gas pedal harder the acceleration goes up as well.  Conversely, is you do not press the pedal, you will not accelerate.  This determines that is I press the gas pedal, it will CAUSE the car to accelerate.  This proves causation.

Now, correlation.  The definition of correlation in statistics is any statistical relationship between two random variables or data.  This simply means that these two events are connected to one another.  A POSITIVE correlation is when two correlated events move in the same direction as one another.  I have added a graph to help visualize this.  In this problem as the gas is pressed harder, the acceleration increases.  If the pressure on the pedal was decreased, then the acceleration also decreases.  If the pressure on the pedal is constant, the the acceleration is constant.

I hope this helps!

A 24 liter tank contains ideal helium gas at 27 degrees C anda pressure of 22 atm. How many moles of gas are in the tank?
frozen [14]

Answer:

d)21.5 moles

Explanation:

Given that

L = 24 L

T = 27 °C = 300 K

P = 22 atm

We know that ideal gas equation

P V = n R T

P=Pressure ,V= Volume ,n=Moles ,R=Universal gas constant ,T=Temperature

Now by putting the values

22 x 24 = n x 0.08206 x 300

n= 21.447 moles

n= 21.5 moles

Therefore the number of moles will be 21.5 moles.

The answer is "d".
