A uniform beam of mass 3.20 kg and length 3.40 m is held up by Support A and Support B. A mass of 24.6 kg is placed 0.2 m from Support A and a mass of 37.1 kg is placed 0.6 m from Support B. All distances are shown in the diagram

Ahot-air balloonist, rising vertically with a constant speed of 5.00 m/s releases a sandbag at the instant the balloon is 40.0 m above the ground. after it is released, the sandbag encounters no appreciable air drag. compute the velocity of the sandbag at 0.250 s after its release.

When does your body conduct current more readily?

Wave functions describe orbitals in a hydrogen atom. each function is characterized by 3 quantum numbers: n, l, and ml. if the value of n = 2: the quantum number l can have values from to . the total number of orbitals possible at the n = 2 energy level is .
