Two positively charged particles are 0.03 m apart. The first particle has a charge of 8.1 C, and the second a charge of 2.6 C. Which change would lead to the smallest increase in the electric force between the two particles? A. Decrease the charge on each particle by 1.0 C. B. Decrease the charge on the first particle by 1.0 C. C. Increase the charge on the first particle by 3.0 C. D. Increase the charge on each particle by 2.0 C.

There are weak or strong attractive forces between atoms of liquids with a high viscosity

(a) assume the equation x = at^3 + bt describes the motion of a particular object, with x having the dimension of length and t having the dimension of time. determine the dimensions of the constants a and b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.) (b) determine the dimensions of the derivative dx/dt = 3at^2 + b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.)

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.
