An athlete holds a 32.8 N pole in equilibrium by exerting an upward force U with her left hand and a downward force D
with her right hand as shown. Point C is the centre of gravity of the pole. (Let L1 = 2.25 m, L2 = 1.35 m, and L3 = 0.900 m. Due to the nature of this problem, do not use rounded intermediate values in your calculations—including answers submitted in WebAssign.)

Which force is most responsible for binding together an atom's protons and neutrons? electrostatic gravitational nuclear magnetic

Física: un futbolista patea hacia el arco con una velocidad de 15m/ah, calcular: a)el alcance para un ángulo de tiro de 25? , b) el tiempo que el balón permanece en el aire.

The chart shows the costs and shipping times for materials that a company needs to build a new product. which describes the best trade-off if the company needs to start building their product within the next two years? they should order the domestic materials because it is always best to choose the fastest shipping time. they should order the imported materials because it is always best to choose the lowest cost for materials. since the shipping time is longer, they should order the domestic materials because the additional cost is worth it to get the materials in time. even though the shipping time is longer, they should order the imported materials because they are less expensive and should arrive in plenty of time to build the product.
