Three warehouse workers are moving a heavy crate from the warehouse to the truck. Looking at them from a top-down view, worker A pulls the box to the North with a force of 10N, worker B pulls the box to the West with a force of 17N, and worker C pulls the box to the South with a force of 20N. The box moves a total of 18m, 20° S of W with the force of the workers. What is the work done by Worker C?

The equivalent resistance of two resistors R1 and R2 is given by 𝑅𝑒𝑞 = 𝑅1 + 𝑅2 and 𝑅𝑒𝑞 = 𝑅1𝑅2 𝑅1+𝑅2 when they are connected in series and parallel respectively. If 𝑅1 = 22.0 Ω ± 5% 𝑎𝑛𝑑 𝑅2 = 47.0 ± 5% , find the maximum error in the calculation of their equivalent resistance when they are connected in series and parallel.

a velocity of magnitude 40 m/s is directed at an angel of 40 east of north draw a vector on pepera to represent this velocity
