What is the acceleration of the stone if it is dropped from the top of a tower?
The acceleration will be equal to the acceleration due to gravity. Unless otherwise stated, one can assume this to be 9.81 meters/seconds It has nothing to do with the mass of the stone.
Which would fall with greater acceleration in a vacuum a leaf or a stone?
Assuming by 'fall' we mean undergo the effects of gravity. If the two objects are falling toward the same large mass (ie falling towards Earth) then they would both accelerate at the same rate. This rate happens to be about 9.8 meters per second squared. It is the acceleration due to gravity on earth.
Do you agree with the statement an object with a zero velocity can have an acceleration greater than yero?
Of course. Toss a stone straight up. -- From the moment it leaves your hand until the moment it hits the ground, it has constant acceleration ... the acceleration of gravity, around 10 meters per second2. The number isn't important, only the fact that the acceleration of the stone is not zero until it hits the ground. -- Velocity-wise: The stone starts out with some upward velocity, which steadily decreases until it's at the top of its arc, then the velocity becomes downward and increases until the stone hits the ground. -- At the very top of the arc, there is a point where the velocity changes from upward to downward. In order for that to happen, there must be an instant when the velocity is zero. -- But the acceleration is constant and not zero, even at that instant when the velocity is zero.
Can an object have zero velocity and non-zero acceleration?
Yes, an object can have have zero velocity and non-zero acceleration. This happens when an object is at rest and when a force is applied on it such as gravity. But this isn't always true. A good example of another situation is when you throw an object vertically up into the air. Such an object will be acted upon by the constant acceleration of gravity. Due to this acceleration, it will slow down, then it will reverse direction, and finally it will fall back to the ground. At the exact point at the top of its path before falling back down, the object will have zero velocity. Yet it will still be accelerating towards the ground the whole time. The object is being accelerated by the force of gravity throughout its entire journey.
What is the difference between apparent specific gravity and absolute specific gravity and bulk specific gravity?
Dry Bulk Specific Gravity does not take into account for anything getting into the permeable or impermeable voids of say a stone by water for instance. Saturated Surface Dry Bulk Specific Gravity takes into account for anything getting into the permeable voids only of say a stone by water. Apparent Specific gravity takes into account for the volume of the impermeable voids and not anything getting into the permeable voids of say a stone by water.

What is the action and reaction in case of a stone suspended by a string?
Downward force on the stone ===> force of gravity. Upward force on the stone ===> tension in the string. Downward force is equal to the upward force. Total (net) force on the stone is zero. Acceleration of the stone is zero. It just hangs there.
A falling stone has zero acceleration?
Only if it has enough wind resistance to cancel out gravity.
When is meant by accleration due to gravity?
Dropping a stone from a tall building is an example of acceleration due to gravity. The stone's speed will increase as it falls until it reaches terminal velocity.
What are the units of gravitational pull?
Acceleration of gravity is equal to negative 9.8 metres per second squared.The so-called "pull" of gravity is a force. The only difference between the 'pull'of gravity and the 'pull' of a rope is the direction. They're both forces.Here are some widely used units of force:-- newton-- pound-- ton-- stone-- ounce
Why does a stone of mass of 5 grams falling from a height of 100 meters causes more danger than a stone of mass 10 grams falling from a height of 1 meter?
Both stones have the same acceleration (gravity) but the the 5 gram stone falls over 100 meters and builds up higher speed; and although the 10 gram stone s heavier the energy is much higher at impact for the 5 gram stone. The energy is simply E = mgh wher m = mass; g = gravity acceleration and h = distance. Since both have same gravity acceleration, you can see that energy is higher for the 5 gram stone; mgh = 500 g for 5 gram stone mgh = 10 g for 10 gram stone
A stone falls from rest how fast is it falling after 10 seconds?
Speed = (acceleration) times (time)Acceleration = gravity = 9.8 meters (32.2 feet) per second2Speed = 10g = 98 meters (322 feet) per second
Can an object with a constant acceleration reverse its direction of travel?
Of course. Anything you toss with your hand has constant acceleration after you toss it ... the acceleration of gravity, directed downward. If you toss it upward, it starts out with upward velocity, which reverses and eventually becomes downward velocity.
Which would fall with greater acceleration in a vacuum a leaf or a stone?
Assuming by 'fall' we mean undergo the effects of gravity. If the two objects are falling toward the same large mass (ie falling towards Earth) then they would both accelerate at the same rate.

Stone is dropped from the top of tower one second later another stone is thrown verticaly downward from th same point with velocity of 14ms.if they hit th ground together find the height of the tower?
It would take too long to explain all the math, so here are some answers:If you use acceleration due to gravity = -10m/s^2:height = 25.3125mIf you use acceleration due to gravity = -9.81m/s^2:height = 25.1640625m

What is A 0.25 kg stone tied to a 0.5 m string whirls at a speed of 4 m s What is the centripetal acceleration acting on the stone?
Centripetal acceleration = V2/R = (4)2/(0.5) = 32 meters/sec2The centripetal acceleration doesn't depend on the stone's mass.(The centripetal force does.)The centripetal acceleration doesn't "act on" the stone.(The centripetal force does.)The centripetal force acting on the stone is F = M A = (0.25) (32) = 8 newtons.
