How would the velocity of the book change if the applied force were equal to the sliding friction force?
The book slides with constant velocity.
Objects moving at a constant speed in a straight are said to be in?
Objects moving at constant speed in a straight line are said to be in equilibrium. That is there is no force acting on them. If a force was acting there would be aceleration and the velocity would change.
Is an object in motion if the acceleration is zero?
Acceleration just means that something is getting faster at a constant pace. If the object was at rest it would have a constant velocity. If the object was then acted upon by and unbalanced force, the velocity would change and no longer be constant. However if an object is just moving along (balanced force of air resistance, gravity, and friction) then it would be at a constant velocity, also. In motion or at rest and object can have zero acceration.
What is the net force on an object with constant velocity?
If the object is moving in a straight line, then the net force on it is zero. If the object is not moving in a straight path, then there is some non-zero net force acting on it even if its speed is constant. We don't have enough information to describe the magnitude or direction of the force.
What is constant volume?
The constant Volume process, also known as Isovolumetric, is where the volume is constant and does not change. In a P, V, Diagram this should be where volume is constant where Pressure is increased. The work done (area under the curve) would be = to 0 in this case.
How would pressure change if area is doubled keeping the force constant?
Since P = F/A, PA = F So, if area is doubled, pressure is halved.
Can you produce a lower pressure by decreasing the area a force acts on?
No, in fact you would be increasing the pressure. What you would have to do is increase the area while keeping the force constant which then would decrease the pressure.

Would swimmming fish in a tank change the weight distribution of the whole tank or is the weight constant throughout?
The weight distribution is constant because fluids transmit pressure evenly.
What is the volume of air in the tank of capacity 1500cc if you pump only 500cc?
Assuming the tank was not in a vacuum, the VOLUME stays constant. The volume is the total area inside the tank. The pressure would change when 'pumped up'. The volume would not. The pressure inside would also change based on the temperature, relative to the outside pressure.

If you slide a hockey puck across a frictionless ice rink these must be a horizontal force on it too keep it in the motion?
F=ma constant speed would mean 'a' acceleration is zero thus force zero. The puck would be in equilibrium, and the force would be zero at constant motion. Constant motion is constant velocity including the constant zero velocity.
What does pressure times volume equal?
As pressure is force per unit area (Newtons/m2) and volume is m3, then PV would simplify to Newtons*meters which is joules.
What is the net force on an object with constant velocity?
If the object is moving in a straight line, then the net force on it is zero. If the object is not moving in a straight path, then there is some non-zero net force acting on it even if its speed is constant. We don't have enough information to describe the magnitude or direction of the force.
At a constant temperature what is the impact to volume if the pressure is increased?
Volume & pressure are inversely proportionate, if temperature stays constant volume would decrease at a factor proporionate to the increase in pressure.
What happens to volume when temperature of gas is decresd at constant pressure?
If the temperature of the gas is decreasing, then in order to maintain constant pressure, you would have to compress it in volume.
