Homework Statement a.) What is the lowest number represented by a 12-bit machine using Sign Magnitude? b.) What is the largest? c.) What decimal number does the bit pattern "101001010010" represent?Homework Equations For a and b: Signed integer ranges for N bits (I don't know if this is...

In my food and culture/biology class, our teacher played an audio file about untapped maple trees exploding, but after it was over, she told us it was an April Fool's prank. However, I am curious to know. Why don't untapped maple trees explode?

I meant .57m for radius. Would that be right, or would I use 1.14 for the distance/radius in the equations? How would I find the force then if it doesn't make sense?

I need to figure this question out. I have to find the tension on the rope (1.14m) after swinging an airplane (.115kg) in the air for 1.49s. Any help? I did it like this. I found the velocity (v=d/t) using .82m as the distance (radius) (or should I have used 1.14m instead?). The velocity...

And v^2 is just the velocity squared? I didn't get the parabola for the Fc vs. V graph.

I have to find the centripetal force and velocity of an object being swung around on a string that is attached to a weight (starting at 200 grams up to 1100 grams). The length of the string (radius) that is swinging the object is .5 meters. I have the times for each mass (200g-1100g). How...

How would I find the tension of a rope that is attached to an object being swung around in a circle? If I find the centripetal force would that be the same thing as the tension?

What I'm asking is should the static coefficient of friction always be less than the kinetic and the kinetic always be less than rolling?

What is the relationship between static, kinetic, and rolling? Is static supposed to be less than kinetic and kinetic less than rolling? Can someone help me out?

Which way is closer to the actually velocity of a car rolling down a ramp and falling off a desk to the floor? Finding the final velocity (Vf) or finding the horizontal velocity (Vx)? Why?

Do I have to do Viy=Vi*sin(X) repeatedly until the equation is Viy=Vi*sin(70)? Do you have a screen name so we can talk one-on-one?

Find the dx for an object projected at 100 m/s from 20 degrees to 70 degrees in 5 degree intervals. How would you exactly do this? Would you use the equation Ay = A sin X?
