Honeybees accumulate charge as they fly, and they transfer charge to the flowers they visit. honeybees are able to sense electric fields; tests show that they can detect a change in field as small as 0.77 nc. honeybees seem to use this sense to determine the charges on flowers in order to detect whether or not a flower has been recently visited, so they can plan their foraging accordingly. as a check on this idea, let's do a quick calculation using typical numbers for charges on flowers. if a bee is at a distance of 24 cm, can it detect the difference between flowers that have a +30 pc charge and a +40 pc charge?

What is the primary force that suspension bridges use cables to hold their spans up? a. tension force b. resistance force c. normal force d. elastic force e. applied force

Click the game tab at the bottom of the simulation and select level 1. (there is no seesaw balance for this part of the activity.) balance the first equation, and click check to see if you got it right. if you can’t balance it in the first try, you can try again. work through the five equations for level 1. click continue to go on to level 2, and later level 3. each level is more difficult than the one before. keep trying until all the equations are balanced. in one or two sentences, describe how you did in the balancing game. in a few more sentences, explain one strategy you learned for balancing more complex equations.

State the following: boyle's law and charle's law
