At tt 0 a very small object with mass 0.275 mg mg and charge 9.00 μCμC is traveling at 125 m sm s through the origin in the xx direction The charge is moving in a uniform electric field that is in the y y direction and that has magnitude EE 895 N CN C The gravitational force on the particle can be neglected

Work = force × a. work b. energy c. distance d. momentum

Rank the six combinations of electric charges on the basis of the electric force acting on q1. define forces pointing to the right as positive and forces pointing to the left as negative. rank positive forces as larger than negative forces. q1,q2,q3 = positive(+) q1 = + q2 = + q3 = - q1 = + q2= - q3= + q1= - q2= + q3= + q1= + q2= - q3= - q1,q2,q3 = negative

Asynthetic fiber used in manufacturing carpet has tensile strength that is normally distributed with mean 75.5 psi and standard deviation 3.5 psi. how is the standard deviation of the sample mean changed when the sample size is increased from n equals 8 to n equals 47
