13/2 = 6.5 Km/h
That’s 6500/3600= 1.8 m/s
The answer should be c....
Answer:
the answer would be A and B
Explanation:
acceleration = change in velocity / change in time
a = v2-v1
- - - - - -
t
V1 = 0 ( since she stopped)
V2 = 9 m/s
t =15s
a = 9 - 0
- - - -
15
= 0.6m/s^2
Answer:
P = 359.8 atm
Explanation:
The van der Waals' equation relates the properties of a gas, introducing constants "a" and "b" in order to consider gases as real gases. The equation is:

where,
P: pressure
a: correction factor for intermolecular forces
V: volume
b: correction factor for molecules' volume
n: moles
R: ideal gas constant
T: absolute temperature
