If you removed air resistance would objects fall with constant acceleration?

Yes. Neglecting the effects of air resistance, all objects near the surface of the earth fall with the same constant acceleration, regardless of their mass/weight.

A sentence for negative acceleration?
Yes, negative acceleration is slowing down. Take the example of a car going from 0 to 60 mph this would be positive acceleration. If once it reaches 60 mph the foot is removed from the petal the car will continue to move but due to friction and wind resistance it will begin to slow down, while slowing down it is in negative acceleration.
What is an object that continoues to move when an unbalenced force is removed?
Any moving object continues to move, in a straight line and at constant speed,when all forces are removed from it.
Why are objects seen more clearly in a distance after rain?
This is because the dust particles are removed after rain
Do objects of the same mass but of different shapes fall at the same rate?
All objects are equally influenced under the effect of gravity, no matter what size 'surface area', what mass or shape. All objects accelerate at 9.8 m/s assuming there is no air resistance. However every object is differently affected under the influence of air resistance. e.g. objects with greater surface would have slower speed through the air.
Why do objects accelerate during free fall?
Earth's gravity pulls all objects toward its center of mass, or in most cases toward the surface. Gravity is a property of matter,and causes every mass to exert a force on every other mass. In this case, the Earth's gravity applies a force to every object on it, and that force will accelerate an object toward the Earth's center, unless it is prevented by some intervening mass. It will still have the potential to accelerate again if the intervening mass is removed.

Do air molecules affect the speed of falling objects?
Yes. It's called wind resistance and is the reason why paper falls slower than a rock. If two objects are put in a perfect vacuum, where all of the air is removed, a feather will fall as fast as a one ton weight. Gravity effects all objects in the same way, and wind resistance is the only reason they fall at different rates.
Why the load must be removed when to conduct the insulation and resistance testing?
explain why all the load must be removed when to conduct the insulation and resistance testing
When one load is removed from a parallel circuit the total resistance decreases?
No, the total resistance increases.
Conflicting ideas of Galileo and Aristotle about motion?
af Example: a hammer falls faster than a feather Galileo: Proved that an objects mass has no effect on its rate of acceleration as it falls. What causes things to fall at different rates here on earth is air resistance. Aristotle: Believed that heavier objects fall faster than lighter object af Example: a hammer falls faster than a feather Galileo: Proved that an objects mass has no effect on its rate of acceleration as it falls.

Do all objects accelerate the same when they are dropped?
If we are to neglect air resistance, then yes. There is a video of the Apollo 15 astronauts putting this to the test on the moon, using a feather and a hammer. When the astronaut drops the objects, they hit the ground at the same time. The video is on YouTube.
What happens to the current in a circuit if a 10 ohm resistor is removed and replaced by a 20 ohm resistor?
Voltage, current, and resistance can be related by this formula. V = iR, where I is the current. Assuming that the voltage stays constant, current will decrease. Hope this helps!
How maximum output power obtained?
when all the resistance removed from the circuit
When the resistor removed from a parallel connection of the circuit whether the resistance increase or decrease?
if we remove a resistor from the parallel connection the effective resistance value will be increased.
In a series circuit is resistance constant?
current
What is an object that continoues to move when an unbalenced force is removed?
Any moving object continues to move, in a straight line and at constant speed,when all forces are removed from it.
What do after having your appendix removed?
When the appendix is removed it is usually due to appendicitis. The doctor will recommend that you do not lift heavy objects for 6 weeks, and not allow the stitches to get wet.
