to unstable state and also according to the definition of torque‚ applied forces multiplied by level arm. In balancing‚ I observed that the pan containing bigger mass will positioned closer to the axis of rotation while the pan containing smaller mass will positioned farther to the axis of rotation so that the amount of the torques that we may get in the two pans will be equal if equate them both. Also‚ when the beam is balance‚ the equilibrium is established‚ the weight and the perpendicular distance

rotational motion of a particle. It is also called the moment of force. It is always specified with regard to the axis of rotation. On the experiment the axis of rotation serves as the model balance. This means that as much as torque is directly proportional with the force applied on a particle‚ it is also dependent on the perpendicular distance of the applied force to the axis of rotation. On the first activity we need to determine the weight of the pans. At first we had a difficulty or rather error on

fall. The farm supports two types of livestock: dairy cows and laying hens‚ as well as three crops: soybeans‚ corn‚ and wheat. (All three are cash crops‚ but the corn also is a feed crop for the cows and the wheat also is used for chicken feed.) The crops are harvested during the late summer and fall. During the winter months‚ John‚ Eunice‚ and Grandpa make a decision about the mix of livestock and crops for the coming year. Currently‚ the family has just completed a particularly successful harvest

Many wild animals are potential competitors to humans for food resources or threats to human life.

The Effects of ECB on Corn Crop Yield Abstract In this experiment we explore the infestation of ECB (European Corn Borer) on different types of corn and how it effects the corn crop yield. The corn is grown in a controlled environment with the only changing variables being the type of corn and the concentrations of the infestation of the ECB. Varying levels of infestation are tested on a corn crop throughout a 140 day growing season‚ at the end of the season the crops are then measured for yield

Abstract: In this investigation‚ a mass was attached to a string and was swung horizontally for certain number of rotations (ten). The sole goal for this investigation was to find and verify the relationships between Centripetal Force‚ Frequency and Radius of circular path. In order to get relationships between the variables mentioned above‚ this experiment was divided into two parts. In Experiment A‚ the radius of the path (length of the string)‚ along with the mass was kept constant‚ and the relation

This particular potato‚ however was overcome by a disease called late blight. Eventually almost the entire potato crop had become diseased leaving behind infertile soil for new crops to grow. With no potatoes the people starved which then caused the population in Ireland to crash (Kniss). No good comes out of taking up crazy amounts of land to plant one crop over and over again. When crops are repeatedly planted in the same place‚ the soil becomes nutrient deficient. The way to introduce these nutrients
