    What is the radius of the circle?

    I know. It was a case of me trying to turn a simple problem into a more complex one. For some reason, I was thinking i had to convert the 1.8 radians into something else. Simple things smack me in the face. :)

    What is the radius of the circle?

    Nevermind...think I figured it out. Radius of 1.666666667 feet, or 20 inches sound right?

    What is the radius of the circle?

    "Use the formula s = rθ ( "θ" is NOT an 8) to solve the following problem. An arc of 3 feet subtends a central angle of 1.8 radians. What is the radius of the circle?" How do I do this problem?

    Physics Problems: Rainfall Power, Gravitational Force, and Lever Efficiency

    The problem asks me to find the gravitational force and the centripetal acceleration. Does an acceleration of 1.13 x 10^-17 sound right?

    Physics Problems: Rainfall Power, Gravitational Force, and Lever Efficiency

    F = ma, so do I find the acceleration of the electron by dividing the force of gravitation by the mass of the electron?

    Physics Problems: Rainfall Power, Gravitational Force, and Lever Efficiency

    Since the formula for centripetal acceleration requires a radius, do I use the distance between the proton and electron as the radius? What do I use for "v"? Using only 0.01m as the distance, the output is 98 N*m. Input is 350 N*m if I am correct in using a radius of 1.11xxxx to find the...

    Physics Problems: Rainfall Power, Gravitational Force, and Lever Efficiency

    I still do not have a clue how to calculate the centripetal acceleration for problem 2 so moving onto problem 3: The end of the lever of a tire jack travels 7 m for every centimeter that it lifts the car. If the car has a mass of 1000 kg and a force of 50 N is needed to lift the car, what is...

    Physics Problems: Rainfall Power, Gravitational Force, and Lever Efficiency

    Back to problem 1: Is the answer to problem one 68,055,555 watts? Here is my process: 2.5 x 10^10 cc = 2.5 x 10^10 g = 25,000,000 kg * 9.8 N/kg = 245,000,000 N (245,000,000N)(1,000m)/(3600 seconds) = 68,055,555 N*m/sec = 68,055,555 watts Can someone please just tell me if I am right...

    Physics Problems: Rainfall Power, Gravitational Force, and Lever Efficiency

    You are just confusing me even more. Problem 2: Without looking it up, I assume the formula a = mv^2/r is such that m = mass, v = velocity, and r = radius. Where in the problem do I find the radius and velocity?! Problem 3: I "think" I have already figured half of the information...

    Physics Problems: Rainfall Power, Gravitational Force, and Lever Efficiency

    Problem 1: I need you to check the first problem. The answer makes me think I may have done something wrong. 1) A quantity of water equal to 2.5 x 10^10 cc falls from a rain cloud that is 1000 m high. If this rain falls in just 1 hour, how much power is generated? The formula I used...
