The answer is:
All the above
The explanation:
The volume and the temperature and the number of particles will affect the pressure of an enclosed gas.
because according to boyle's law when the temperature constant so the pressure and volume of a gas have an inverse relationship, when temperature is constant.
when:
PV = nRT
when p is the pressure
V is the volume
n is number of moles
T is temperature
from this law we can know that there is a relation between P and V and when n has a relation with the number of particles so:
volume , temperature and number of particles affect the pressure of an enclosed gas.
A mass movement that involves the sudden movement of a block of material is called a B.slide.

Answer:
The factors that affect an object's gravitational potential energy are its height relative to some reference point, its mass, and the strength of the gravitational field it is in.
Answer:
1) p₀ = 45000 N / s
, p₀ '= 1800
, b) I = -45000 N s
, I = 1800 Ns
Explanation:
Impulse equals the change in momentum
I = Δp
1) the initial moment of the car
p₀ = M v
p₀ = 1500 30
p₀ = 45000 N / s
the change at the moment is
Δp = 45000
because the end the car is stopped
moment of the person
P₀ ’= m v
p₀ '= 60 30
p₀ '= 1800
D₀ '= 1800
2) of the momentum change impulse ratio
car
I = Δp
I = -45000 N s
person
I = Δpo '
I = 1800 Ns
3) the object that give the momentum to stop the wall motoring
The person is stopped by the impulse given by the car
a) This area is the one that absorbs most of the vehicle impulse
be) If using a safety painter, the time during which the greater force will act, therefore the lessons decrease
c) The air bag helps reduction in the speed of the person relatively quickly.
