There's a 6 ft wall. Support beam is 1 foot less than 3 times the length of the ground. The support beam goes from the top of the wall to the ground. What is the length of the beam? I got 30 ft... is this correct? I came up with the equation 3x(3x-1) = 6 and then converted that to 9x^2 - 3x - 6 and then worked from there....Did I do this wrong?

Can anyone please tell me why long wires provie more resistance than short wires in as much scientific detail as possible? Ignoring thickness. I'm confused... is it because more electrons collide with more atoms, increasing the energy transfer form kinetic energy to thermal energy? S.O.S

A space station consists of a circular tube which is set rotating about its center (like a tubular bicycle inner tube). The circle formed by the tube has a inner diameter of 1.5 km and an outer diameter of 1.6 km.

-- Where will the people inhabit this space station?

-- What must the rotation speed be if an effect equal to Earth’s gravity at the surface is to be felt by its occupants?

-- What torque must be applied to the station if it is to attain this speed from rest in two hours and the mass of the station is 187,016 kg?


can someone help? thanks

:-)
