There is 260g block on a 50cm -long string swings in a circle on a horizontal frictionless table at 50rpm What is the speed of the blockWhat is the tension in the string?

The linear speed will be: v = 2 * pi * r * f, where r is circle radius, f is rotations per second. To calculate tension, we can use formula for centripetal force, which is: F = mv2 / r. This centripetal force will be the tension in the string.


Why does the length of a string on a pendulum change the number of swings?

The length of the string has nothing to do with the number of swings. Itdetermines the time that each swing takes. That has no connection withthe number of swings, unless you're in a hurry and can't wait around.


What affects the rate at which a pendulum swings?

the legth of the string. the longer the string the longer it will swing for where as if it's really short it stops at a short time.


What you change in your swinger that might change the number of swings in 15 seconds?

make the string longer


Does changing the mass of the pendulum affect the number of swings?

No. Only the length of the string and the value of g does.


How do the mass of a pendulum affect the numbers of swings?

Not at all, as long as the mass of the 'bob' is large compared to the mass of the string.


A father swings his child around in a circle The source of the centripetal force that keeps the child moving in a circle is friction or weight or gravity?

The source of the centripetal force that keeps the child moving in a circle is tension in the rope or the father's grip. This force is directed towards the center of the circular motion and prevents the child from flying off tangentially. Gravity and weight also play a role in the overall forces acting on the child but are not the direct source of the centripetal force in this scenario.


How do you make a pendulum that constantly swings back and forth?

You can attach any object - a small stone, for example - to a piece of string.


Does the string that supports a pendulum bob do work on the bob as it swings to and fro?

No. Work is force times displacement. Even though the pendulum moves, it has zero displacement in the direction of the force imparted by the string.


What is dutty wine?

Dutty wine is a popular dance in Jamaica in which a girl swings her hair wildly in a circle.


What is the relationship between the length of the string of a pendulum and the number of swings?

There's no relationship between the length of the pendulum and the number of swings.However, a shorter pendulum has a shorter period, i.e. the swings come more often.So a short pendulum has more swings than a long pendulum has in the same amountof time.


What to do when in the deck circle on a softball game?

When you are in the on deck circle, it means you are next to be at bat. Therefore you need to be ready by having your helmet on and if you need/want batting gloves they should be on too. While in the on deck circle, you should be watching the pitcher and trying to time your swings. Take a few practice swings as he or she pitches so you can be prepared when you are actually up to bat.
