Answer: D. 332n
Explanation: I took the quiz and that was the correct answer
Answer:
Distance, d = 0.049 meters
Explanation:
It is given that,
Mass of the pile, m = 2500 kg
It is dropped through a height of 8.0 m on each stroke, h = 8 m
The resisting force of the ground,
The work done in each stroke is equal to the potential energy of the pile driver such that,
Work done due to resistive force is :
So,
d is the distance covered by the post driven in on each stroke.
d = 0.049 meters
So, on each stroke the post driven is 0.049 meters far. Hence, this is the required solution.
This question is incomplete, the complete question is;
The Figure shows a container that is sealed at the top by a moveable piston, Inside the container is an ideal gas at 1.00 atm. 20.0°C and 1.00 L.
"What will the pressure inside the container become if the piston is moved to the 1.60 L mark while the temperature of the gas is kept constant?"
Answer:
the pressure inside the container become 0.625 atm if the piston is moved to the 1.60 L mark while the temperature of the gas is kept constant
Explanation:
Given that;
P₁ = 1.00 atm
P₂ = ?
V₁ = 1 L
V₂ = 1.60 L
the temperature of the gas is kept constant
we know that;
P₁V₁ = P₂V₂
so we substitute
1 × 1 = P₂ × 1.60
P₂ = 1 / 1.60
P₂ = 0.625 atm
Therefore the pressure inside the container become 0.625 atm if the piston is moved to the 1.60 L mark while the temperature of the gas is kept constant
Answer:
At point A, the cart has high potential energy. At point b, the cart is pulled down by gravity. At point c, the cart gains its highest kinetic energy. At point d, the cart returns back to the same state but with lower potential energy.
