A boy is swinging a yo-yo with mass 0.5 kg in a circle with radius 1.5 m at a speed of 6 ms. What is the tension in the string connecting the yo-yo to the boy's finger disregarding gravity?

How many microliters are in one drop?
The size of a drop depends on the surface tension of the liquid (and gravity). A standard medicinal drop 50 microlitres.
What is the tension in a rope that is supporting a 4.2 kg bucket?
There are two forces acting on the bucket which are the Tension and the Weight. Tension is directed upward and Weight is directed downward. Since the bucket is either moving at constant velocity, or if its remaining still, the Tension would have to equal in magnitude to the weight. Weight = Fg = Mass(in kgs) times Gravity= 4.2 kg x 9.8 m/s^2=41.46 Newtons Tension would be equal to Fg, which means that Tension would also be 41.46 Newtons.
What is the force of gravity on the mass of 0.5 kg hanging on a string in a beaker of water?
The force of gravity acting on it is 4.9 newtons (1.102 pounds), provided the beaker is in a lab on Earth. We don't know the buoyant force on it, because we don't know its volume. Whatever its volume is, you can subtract the weight of an equal volume of water, and the result is the tension in the string.
What is the maximum depth a water spill will be on a flat surface?
Any, depending on the volume of water spilt and the area of the flat surface. The specific height is also constrained by the surface tension of the water, the atmospheric pressure above it, and the gravity below it.
What is a tension graph?
no idea
What causes a pendulum to continue swinging?
Gravity and the tension in the string.
What forces cause a pendulum to continue swinging?
Gravity and the tension in the string.
What is the name of the force when a swing is swinging?
The force that keeps a swing swinging is primarily gravity. The swinging motion is a result of the interplay between gravity pulling the swing downward and the tension in the chains or ropes supporting the swing.
Does the tension in the string of a swinging pendulum do any work?
No, the tension in the string of a swinging pendulum does not do any work. The tension force acts perpendicular to the direction of motion, so it does not apply a force in the direction of displacement. This means that no work is done by the tension force on the pendulum.
What forces and motion are in a pendulum swing?
The main forces at play in a pendulum swing are gravity and tension. Gravity pulls the pendulum bob downward while tension in the string keeps it swinging back and forth. The motion of the pendulum is an example of simple harmonic motion, where the pendulum swings back and forth with a constant period.
What forces do you feel on a swing set?
You feel gravity and the normal force from the seat of the swing which is applying a force due to the tension from the chains of the actual swing. The tension and normal force is greater than your weight which is why u don't go through the seat and break it. Since u are going in a circular fashion when u swing u also feel centripetal force which is due to the tension of the swing overpowering gravity and keeping u swinging.
What does swinging have to do with physics?
Swinging involves the interplay of various physical forces such as gravity, tension, and centripetal force. The motion of swinging objects can be described using principles of mechanics, including conservation of energy and the relationship between force, mass, and acceleration. In swinging activities like a pendulum or a playground swing, physics concepts are essential to understand and predict the motion of the object.
How the tension can be greater than gravity yet the elevator is moving downwards?
The tension can be greater than gravity when the elevator is accelerating downwards, causing a net force that exceeds the force of gravity acting on the elevator. This creates a situation where the tension in the elevator cable is greater than the force of gravity, allowing the elevator to move downwards.
What enables a pendulum to swing back and forth in a grandfather clock?
The pendulum in a grandfather clock swings back and forth due to the force of gravity. When the pendulum is pushed to one side, gravity pulls it back towards the center. The swinging motion continues because of this repeated force from gravity.
What are the five forces that act upon bridges?
1.compression 2.tension 3.torsion 4.shear 5.gravity
What happens if droplets of condensation become to big?
The force of gravity from the growing mass of the droplet will overcome the force of tension between the droplet and the surface the water tension is "holding" it to. Once gravity is larger than tension, the droplet falls to the ground.
In surface tension what makes the water rise?
because of gravity
