A pendulum clock that works perfectly on Earth is taken to the Moon. Assume that the free-fall acceleration on the Moon is 1.63 m/s2.?
(a) Does it run fast or slow there? fast slow Neither, it runs the same as on Earth. Correct: Your answer is correct. (b) If the clock is started at 12:00 midnight, what will it read after 13.9 h? (Enter the time to the nearest minute.)
You need to know the height of a tower, but darkness obscures the ceiling. You note that a pendulum extending?
You need to know the height of a tower, but darkness obscures the ceiling. You note that a pendulum extending from the ceiling almost touches the floor and that its period is 20 s. The acceleration of gravity is 9.81 m/s 2 . How tall is the tower? Answer in units of m
Help with a pendulum problem?
A man enters a tall tower, needing to know its height. He notes that a long pendulum extends from the ceiling almost to the floor and that its period is 15.5 s. (a) How tall is the tower? (b) If this pendulum is taken to the Moon, where the free-fall acceleration is 1.67 m/s2, what is the period there?
You need to know the height of a tower, but?
You need to know the height of a tower, but darkness obscures the ceiling. You note that a pendulum extending from the ceiling almost touches the floor and that its period is 28 s. The acceleration of gravity is 9.81 m/s2 . How tall is the tower? The equation for the period of a pendulum : Time = 2 * π * (L/g)^0.5 L = length of pendulum in meters g = 9.81 m/s^2 28 = 2 * π * (L/9.81)^0.5 square both sides 28^2 = 4 * π^2 * L ÷ 9.81 multiply both sides by 9.81, and divide both sides by (4 * π^2) 28^2 * 9.81 ÷ (4 * π^2) = L solve for L
Is the Earth flat? I need someone to give me rock hard evidence against individuals who believe the Earth is flat so that I can get them off of my back.
Here are a couple ways to prove to yourself that the Earth is not flat. None of these methods rely on any authority figures, textbooks, astronomical observations, etc. These are things you can do yourself so long as you go to a place with little topography.Go hike to the top of a tall mountain overlooking a prairie by at least 1000 meters**. Bring a long ruler or meter stick. When you are at the top of the mountain, close one eye and hold out the ruler in front of you to try to line up the ruler along the horizon. Can you do it? Or does the horizon bend away from the edges of the ruler? Why would that be?Find a very long, straight road on a prairie on a clear day***. Have a friend go with a second car and tell him to start driving. Using binoculars or a telescope, tell him to keep driving until you can no longer see him. Zero the odometer on your car and then go drive to him. How far did you drive? Repeat as necessary. I’m guessing you drove between 4 and 6 km each time. Why would that be? And why can I give you an estimate of how far you will drive?If you have access to decent survey equipment, then go find some prairie or salt flat and try to walk 5 km North, then 5 km East, then 5 km South and then 5 km West****. Did you end up where you started? If you surveyed it correctly, you should end up about 1 to 2 m east of your starting spot. Why is that? And why can I give you an estimate of how far off you will be from your starting point?**An excellent place to do this is the Front Ranges of the Canadian Rockies. For example, Mount Yamnuska, Mount Burke, Moose Mountain, etc. I’m assuming there are good locations in the Front Ranges of the American Rockies too.***An example where this can be done is between Calgary and Edmonton, Alberta. There is a 40 km stretch of straight road which only varies by about 10 m elevation along the entire stretch. I’m assuming there are also many other similar township and range roads throughout the North American prairies.****This is a much more difficult test to perform than the other two because you would need access to high quality survey equipment and you would need to know how to use it. However, it can be done.
