Hardness, color , and luster.
But since you can pick one, I would say hardness
Answer:
in the downward movement of the movement when the constant is lost
Explanation:
When the coin is on the piston it has a relationship given by
a = d²x / dt²
the piston position is
x = A cos wt
a = - A w² cos wt
the maximum acceleration is
a = - A w²
When the piston raises the acceleration of gravity and that of the piston go in the same direction, when the piston descends they relate it is contrary to gravity, therefore when the frequency increases, the point where the acceleration of the piston is greater than gravity arrives and the coin loses contact.
The point where you lose contact is
a = g
g = A w²
In short, in the downward movement of the movement when the constant is lost
negative acceleration- deceleration
Answer:
3 m/s east

I took a test a got it right
Answer:
B)
D)
Explanation:
Carnot cycle ;
This is the ideal cycle for all type of heat engine.All the process in the Carnot cycle is reversible processes ( those process does not leave any effect on the system as well as surrounding when the process is reversed is known as reversible process).It have four process in which two process is constant temperature and other two is isentropic or we can say that reversible adiabatic.
In the two process(constant temperature) only heat interaction take places and other two process(adiabatic) only work interaction take places.
So the option B and D is incorrect for Carnot cycle.
