Explanation:
.Flame retar,dant plastic additi,ves are compounds added to plastics and other materials to inhibit, suppress or de,lay combustion. These compounds are useful in impending burning in the ign,ition phase of fire. They do not prevent char,ring or melting nor do they increase the heat resistance of a material
Answer:
(b) both the temperature and pressure of the gas decrease.
Explanation:
An ideal gas undergoes an adiabatic expansion, a process in which no heat flows into or out of the gas. As a result, both the temperature and pressure of the gas decrease.
Gay Lussac states that when the volume of an ideal gas is kept constant, the pressure of the gas is directly proportional to the absolute temperature of the gas.
Mathematically, Gay Lussac's law is given by;
Also, according to the first law of thermodynamics which states that energy cannot be created or destroyed but can only be transformed from one form to another. Thus, the ideal gas does work on the environment with respect to the volume and temperature.
The relationship between the impulse and the momentum allows to find the result for the question about the contact time is:
-
The contact time on the floor is t = 0.60 s
The impulse is the push force on a body and is related to the variation of the amount of momentum.
I = ∫ F. dt = Δp
p = mv
where I is the momentum, F the force, t the time, p the amount of momentum and m the mass .
They indicate the average force F = 330 N, the jump height is y = 12.0 cm = 0.120 m.
F. t = m v_f - m v₀
Let's search with kinematics for the initial speed of the jump.
v² = v₀² - 2 g y
At the highest point the velocity is zero.
0 = v₀² - 2ay
Let's calculate.
v₀ = 1.53 m / s
Suppose that the jumps are elastic, that is, that the speed with which it reaches the ground is equal to the speed with which it leaves, but in the opposite direction.
Let's calculate.
t = 0.60 s
In conclusion using the relationship between impulse and momentum we can find the result for the question about the contact time is:
The contact time on the floor is t = 0.60 s
