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 magnitude of the tension in the cord?
Tension = mass(acceleration) + force of gravity Force of gravity equals mass times gravity (9.8m/s2)
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 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
What is the net force of gravity tension friction and air tension?
The net force refers to the vector sum of the individual forces.
How the tension can be greater than gravity yet the elevator is moving downwards?
The extra tension depends not on the velocity of the elevator, but on its acceleration.
Why does surface tension and capillary action occur in water?
because of the gravity
Liquid surface disturbance not caused by surface tension?
Gravity Wave?
What two forces act on you while you are in a moving elevator?
Gravity and tension
