Asteel wire of diameter 1 mm can support a tension of 0.24 kn. suppose you need a cable made of these wires to support a tension of 24 kn. the cable should have diameter of what order of magnitude?

Calculate the first and second velocities of the car with four washers attached to the pulley, using the formulas v1 = 0.25 m / t1 , and v2 = 0.25 m / (t2 – t1) where t1 and t2 are the average times the car took to reach the 0.25 and the 0.50 meter marks. record these velocities, to two decimal places, in table e.
