When you lift an object by moving only your forearm, the main lifting muscle in your arm is the biceps. suppose the mass of a forearm is 1.40 kg . if the biceps is connected to the forearm a distance dbiceps = 2.50 cm from the elbow, how much force fbiceps must the biceps exert to hold a 1000 g ball at the end of the forearm at distance dball = 33.0 cm from the elbow, with the forearm parallel to the floor? how much force felbow must the elbow exert? draw the vectors starting from the point of application of each force. the location and orientation of the vectors will be graded. the length of the vectors will not be graded?

(science)study the following ocean currents map. an ocean currents map is shown. on the map the locations for san diego, california and savannah, georgia are marked. there is a looping current from the north past san diego and a looping current from the south near savannah which statement is most likely correct about the average temperatures in san diego, california as compared to savannah, georgia? it is higher in savannah because of the cool ocean currents from the south. it is higher in savannah because of the warm ocean currents from the north. it is lower in san diego because of the warm ocean currents from the south. it is lower in san diego because of the cool ocean currents from the north.
