Why water flows in a continuous stream in a vertical pipe where as it breaks into drops when falling freely?
Water flows in a continuous stream in a vertical pipe due to the cohesive forces between water molecules that keep them together, along with the pressure exerted by the surrounding fluid. In contrast, when water falls freely, gravity causes the stream to accelerate downward, but surface tension and air resistance can disrupt the flow, leading to the formation of drops. The balance of these forces results in the continuous stream in the pipe and the breakup into droplets during free fall.
What else can I help you with?
What is freely body?
A freely body is the body which is freely falling under the force of gravity i.e. an acceleration of 9.8 m/s2
Where does the law of gravity operate?
Freely falling bodies
What are the factors affecting freely falling bodies?
force and gravity
Does an object that is freely falling have mass?
Yes, an object freely falling still has mass. Mass is a measure of the amount of matter in an object, and it remains constant regardless of the object's motion. The force of gravity acting on the object is what causes it to fall.
What is the direction of the acceleration of a freely falling body?
9.8 m/s2
What is a freely falling projectile?
A freely falling projectile is an object that is only acted upon by gravity, moving through the air in a parabolic path while falling towards the ground. It does not have any initial horizontal force or acceleration other than gravity acting upon it.
The sumof the kinetic and potential energies of a freely falling body is?
The sum of the kinetic and potential energies of a freely falling body is constant and equal to the total mechanical energy. This is a result of the conservation of energy principle, where the body's potential energy is converted into kinetic energy as it falls, keeping the total energy constant.
What is the effect of mass of a freely falling body on the gravitational accelaeration?
None whatsoever.
What are some freely falling objects?
The moon, Earth's artificial satelites, etc.
Does the velocity of an object increase when its falling freely in a vacuum?
It accelerates at a higher rate
What is the formula for calculating the vertical distance an object falls?
The vertical distance an object falls can be calculated using the formula ( d = \frac{1}{2} g t^2 ), where ( d ) is the distance fallen, ( g ) is the acceleration due to gravity (approximately ( 9.81 , \text{m/s}^2 ) on Earth), and ( t ) is the time in seconds that the object has been falling. This formula assumes that the object is falling freely under the influence of gravity, with no air resistance.
What is the period of a simple pendulum 80 cm long a- on earth and b- when it is in a freely falling elevator?
none. when there is gravity T=2pi square root of L/g but in a freely falling elevator, there is no accelerate so it doesn't have period the answer is none
