The suspended 2.68 kg mass on the right is moving up, the 2.8 kg mass slides down the ramp, and the suspended 9 kg mass on the left is moving down. There is friction between the block and the ramp. The acceleration of gravity is 9.8 m/s^2 . The pulleys are massless and frictionless. Required:
What is the tension in the cord connected to the 8 kg block?

Suppose a diode consists of a cylindrical cathode with a radius of 6.200×10^−2 cm , mounted coaxially within a cylindrical anode with a radius of 0.5580 cm . the potential difference between the anode and cathode is 260 v . an electron leaves the surface of the cathode with zero initial speed (v initial=0). find its speed vfinal when it strikes the anode.
