a 100g ball on a 60cm long string is swung in a vertical circle about a point 200cm above the floor. The string suddenly breaks when it is parallel to the ground and the ball is moving upward. The ball reaches a height 600cm above the floor . what was the tension in the string the instant before it broke?

in this lab we used a glidder so I wandering how tog et force friction if we have mass, distance, time, final velocity, acceleration, F=ma, Fg=mg.

How do you get Force Friction?

How can any one believe in the big bang for looking at the colors you can see the imagations behind it? I mean if it was just throw together like in the big bang then the grass would not be green it would be yellow or any other color.

I need alot of information on these minerals: Viluite, moss agate, Ocean Jasper, which is also known as Orbicular Jasper, and Wiluite.
I need to add information to the articles on Wikipedia. Thanks!

Be honest. This is a deep question you can remove or add laws. You can take and/or give. I just ask that you really think before you answer.

A weak monoprotic acid (HA) solution consisting of 8.169 grams of the weak acid and 100ml of water has a freezing point of -0.384 degrees celsius. The acid was determined to ionize in the solution to 50%, meaning that 50% of the acid molecules ioniaed to H+ and A- anion. The acid was determined to consist of 14.70% carbon, 65.09% chlorine, 19.59% oxygen and 0.62% hydrogen. What is the molecular formula of this weak acid?

if the symbol for an element is [small number at the top]238[small number at the bottom]92[element]U

[im really sorry if that makes no sense theres no way to type it on here!]

i dont understand what the numbers mean
i think the bottom number is protons
then the top number is the mass number
and the number of neutrons is mass number-protons
so how do you find electrons?

im doing a Force and acceleration lab. I need to collect data for force friction. If I already have mass, distance, time, final velocity, acceleration, force(f=ma), (Fg=mg).

How do I solve for Force friction? What do i need in that list.

Question 2 (if possible)
How do you get Force myu (u) if I have mass, Fg, Ff(kinetic), and F.

How do you get Force myu in this case?
Thanks for your help

One website said that the advantage of a series circuit is that you can add more power devices, such as more batteries, and increase the force of the output. What does that actually mean?
