kg is moving at a speed of 40 km/h on an incline of 1 in 50. The total constant rolling and wind resistance is 600 N. The efficiency of the drive from the engine trough the gearbox to the wheels is 80 % and the gear ratio causes a final engine to wheel velocity ratio of 4:1. The effective wheel diameter is 500 mm. Calculate the engine power to maintain this speed.

Twenty sprint cyclists were randomly selected to be in a study designed to test the effectiveness of 4 weeks of creatine supplementation on performance. Ten cyclists received a creatine supplement for 1month while the other ten received a powdered supplement with the same color and texture that has no physical effect for 1 month. The cyclists did not know which pill they were taking but the researcher did. After 1 month, the researcher switched the creatine and non-creatine groups. The original creatine group became the non-creatine group and visa-versa, while they each went through 1 more month of protocol. This study utilized a placebo.

When a mesh in a circuit contains an independent or dependent current source, this leads to a special case of mesh-current analysis. As you can see, there is only one current source in this circuit: the 50 mA source. When a current source is a component in only one of the circuit's meshes, that current source defines the value of the current in that mesh. What is the value of the current ia?
