Answer:
Explanation:
Volume ,V = 3 L
Initial temperature ,T₁ = 273 K
Initial pressure ,P₁ = 105 kPa
Final temperature ,T₂ = 381 K
Lets take final pressure =P₂
We know that ,If the volume of the gas is constant ,then we can say that
Now by putting the values in the above equation we get
Therefore the final pressure will be 146.53 kPa.
Answer: B
Explanation:
Newton's first law it's law of inertia.
An object at rest will remain at rest (or an object in motion in a straight line at a constant velocity will remain that way) unless it is acted by an unbalanced force.
In A for the ball to slow down and stop, an external force (like friction with air or the floor) needs to be taken in consideration.
In B we can see how we need to make a force on the wagon to make it move.
In C we have an other Newton 's law, force equals mass times acceleration (2nd law)
In D we can see how it does not move because the forces on the box are balanced.
I think it would be from the box to greg
Answer: The average force is 3934.71N
