Suppose that two boys pull a sled with forces of 2.0 x 104 N at a 15° angle to the left of the center of the sled, and 1.8 x 104 N at an angle of 25° to the right of the center of the sled, respectively. What is the net pulling force vector on the sled?

A. 2.1 x 104 N at 80°

B. 2.1 x 104 N at 110°

C. 3.6 x 104 N at 86°

D. 3.6 x 104 N at 102°

The experiment was repeated many years later but the gases were mixed in a different type of container. a white solid was obtained which was xenon fluoride. predict whether you think 1) krypton and 2) radon will react with fluorine. explain reasons for your predictions

An athlete is holding 24 lb of weights at a height of 6 inches above the stack as shown. to lower the weights, she applies a constant force of 5 lb to the handle. determine the velocity of the weights immediately before they hit the stack.

Consider a production line with five stations. station 1 can produce a unit in 9 minutes. station 2 can produce a unit in 10 minutes. station 3 has two identical machines, each of which can process a unit in 12 minutes (each unit only needs to be processed on one of the two machines. station 4 can produce a unit in 5 minutes. station 5 can produce a unit in 8 minutes. which station is the bottleneck station?
