If during an process no flow of heat takes place from system to surrounding for example isolated system then it said to be adiabatic process
The force advantage of the direction changing pulley shown is 1. The correct option is b.
<h3>What is force advantage?</h3>
Force is the mechanical physical quantity. The force advantage is equivalent to the mechanical advantage equal to the ratio of output to the input force.
In the single fixed pulley, there is only one rope segment that pulls up on the load, so,
The force advantage is
F.A = 50 N / 50 N = 1
Thus, the force advantage of the direction changing pulley shown is 1. The correct option is b.

Answer:
I = - m 16 the two impulses are the same,
Explanation:
The impulse is given by the relationship
I = Δp
I = p_f - p₀
in this case the final velocity is zero therefore p_f = 0
I = -p₀
For driver A the steering wheel impulse is
I = - m v₀
I = - m 16
For driver B, the airbag gives an impulse
I = - m 16
We can see that the two impulses are the same, the difference is that in the air bag more time is used to give this impulse therefore the force on the driver is less
Answer: Buildings, walking or cycling
Explanation: Building would slide off of their foundations. If you were cycling then it just wouldn’t work, but if it was in the middle of moving then the brakes most likely won’t work.
