Answer:
Explanation:
By definition, the momentum is given by:
p=m*v
Where,
m: car mass
v: speed of the car
Substituting the values in the given definition we have:
p=3*154
Answer:
the momentum of the car is:
4620g * cm/s
Yes they do if that was your question
Answer:
4.0 moles
Explanation:
The following data were obtained from the question:
Volume (V) = 12L
Pressure = 5.6 atm
Temperature (T) = 205K
Gas constant (R) = 0.08206 atm.L/Kmol
Number of mole (n) =?
Using the ideal gas equation: PV = nRT, the number of mole of the gas can be obtained as follow
PV = nRT
5.6 x 12 = n x 0.08206 x 205
Divide both side by 0.08206 x 205
n = (5.6 x 12)/(0.08206 x 205)
n = 4.0 moles
Therefore, the number of mole of the gas is 4.0 moles
Yeah what the other person said ^
