What would be true of the values for initial velocity and final velocity if the acceleration were zero?
A change in velocity can be effected only by acceleration. Therefore, if the acceleration is zero, there is no change, so final velocity equals initial velocity.
How do you find the distance if only the final velocity and the acceleration is given?
If you take initial velocity(Vi) to be zero and the final velocity (Vo) to be a known. Puting the knowns into a triganonomical equation and solving for the value of D would give an answer
How do you get the volume of an irregularly shaped object?
Using a graduated beaker, add water sufficent to totally immerse the object. Note the initial volume of the water without the object. Put the irregularly-shaped object in the beaker and note the final volume. The difference between the final and initial readings is the volume of the object. This is only possible if the object is not soluble in water. If it is, use some other fluid in which it is not soluble.
What is the force repulsion if each sphere is charged double the above amount and the distance between them is halved?
It's very fortunate that the answer doesn't depend on the amount of the original charge, because I'm really having a lot of trouble reading the above amount. The answer only depends on the changes, and following the changes you've described, the force of repulsion between the spheres is unchanged. If the initial force is marked there in the book you copied the question from, then the final force is exactly the same number.
When two bodies having same momentum collide what will be the result?
There are two possible results. However, they cannot move in the same direction after the collision.Total initial momentum = p - p = 0where p represent the momentum of each object.From the principle of conservation of momentum;Total initial momentum = Total final momentumThus, Total final momentum = 0There are only two possibilities for this:1. Kinetic energy is conserved. (the collision is perfectly elastic)In this case, they would move away from each other with the same magnitude of initial momentum.2. Kinetic energy is not conserved. (the collision is inelastic)In this case, they would either remain at rest or they will move away from each other with a smaller magnitude of initial momentum each had.Note that if both bodies had moved in the same direction, there would be a net momentum in this direction and momentum would not have been conserved. (Momentum is ALWAYS conserved provided there is no external force acting on the system)
How do you find final and initial velocities with the average velocity?
You can't.You only know what half the sum of (initial + final) is, (it's the average), but you don't know what the initial and final are.
Work done is not a state function?
In mechanics,work done(work=force.displacement of body) by a body is independent of path.It only depends on the initial and final state of the body.However in thermodynamics,the work done by an ideal gas(work=pressure.change in volume of gas) depends on the path taken(isochoric,isothermal,isobaric,adiabatic)
How do you find displacement when you only have acceleration initial velocity and final velocity?
Kinematics. Final velocity squared = initial velocity squared + 2(gravitational acceleration)(displacement)
How do you find the time given only the distance and the initial and final velocity?
Average speed = 1/2 (initial speed + final speed) Time = (distance)/(average speed)
When nitrogen stored at 6000 psi is released into the atmosphere what is it's temperature?
The final temperature will depend not only on the initial and final pressures, but also on the initial temperature and whether the expansion is adiabatic.
How do you find the final velocity given only distancetimeand initial velocity?
v = 2s/t - u where u=initial velocity, v=final velocity, s = distance and t = time
What would be true if the values for initial velocity and final velocity if the acceleration were zero?
A change in velocity can be effected only by acceleration. Therefore, if the acceleration is zero, there is no change, so final velocity equals initial velocity.

How do you find acceleration falling object with only speed and distance?
a = (v2 - u2)/2s where a is the acceleration between the initial point in time and the final point in time, u is the initial velocity v is the final velocity s is the distance travelled
Is it true that to calculate acceleraltion you need to know both the final and the initial velocity of an object?
No. That's only one of several possibilities. -- with initial velocity, distance, and time, you can calculate acceleration -- with final velocity, distance, and time, you can calculate acceleration -- with force and mass, you can calculate acceleration -- with initial and final momentum, you can calculate acceleration -- with initial and final kinetic energy, you can calculate acceleration -- with mass, velocity at either end, and kinetic energy at the other end, you can calculate acceleration And I'm sure there are several more that I've missed.
How do you find the initial velocity given only the distance and the time traveled?
You can't. You need either the final velocity or the acceleration of the object as well, and then you can substitute the known values into a kinematics equation to get the initial velocity.
How potential energy independent of path traveled?
It is independent of the path travelled. Its depend only on initial and final position and is a example of conservative force.
