Answer:
Equilibrium
Explanation:
An object is in equilibrium when the vector sum of the force acting on the object is equal to zero.
A body in equilibrium is at state of rest of rest or in motion with no external force acting on it.
- The resultant of all forces acting on the body is zero.
- In this case there is no net force and the body will be at rest.
Answer:
Work: 4.0 kJ, heat: 4.25 kJ
Explanation:
For a gas transformation at constant pressure, the work done by the gas is given by
where in this case we have:
is the pressure
is the initial volume
is the final volume
Substituting,
The 1st law of thermodynamics also states that
where
is the change in internal energy of the gas
Q is the heat absorbed by the gas
Here we know that
Therefore we can re-arrange the equation to find the heat absorbed by the gas:
Well if you had either the velocity or distance traveled i could tell you. But since you haven't all i can say for sure is that the water slowed the bullet down to 13m/s so lets say you knew the distance you would calculate how many meters it traveled and you would have your answer because in this situation, meters (height) =how many seconds spent going into the air.
Answer:
B object at rest
Explanation:
object at rest means it wouldn't be moving, like a parked car or sleeping person therefore, B is the correct answer
