Answer:
0.81452 atm
Explanation:
= Initial pressure = 1.43 L
= Volume
= Initial temperature = (28+273.15) K
= Final temperature = (-35+273.15) K
= Final pressure
From the ideal gas law we have
The pressure in the cylinder is 0.81452 atm
Answer:
The value of the centripetal forces are same.
Explanation:
Given:
The masses of the cars are same. The radii of the banked paths are same. The weight of an object on the moon is about one sixth of its weight on earth.
The expression for centripetal force is given by,
where, is the mass of the object, is the velocity of the object and is the radius of the path.
The value of the centripetal force depends on the mass of the object, not on its weight.
As both on moon and earth the velocity of the cars and the radii of the paths are same, so the centripetal forces are the same.
Can you put the answers, if there are any?
Once you do, Ill respond with a answer asap!

The statement that best describes Keisha errors is an object in either state of equilibrium must have no net force acting on it.
<h3>What is an object at dynamic equilibrium?</h3>
An object is said to be on a dynamic equilibrium when it moves at a constant speed, and all the forces on the object are balanced.
An object is also said to be on static equilibrium when it is unable to move because all the forces which act on it compensate for one another.
Therefore, the statement that best describes Keisha errors is an object in either state of equilibrium must have no net force acting on it.
